High expression level of homocitrulline is correlated with seborrheic keratosis and skin aging

Abstract Backgroud Homocitrulline (Hcit), is involved in the pathological processes of some diseases. However, the role and function of Hcit (CBL) in human skin remains largely obscure. Objective To investigate the correlation of the level of Hcit in seborrheic keratosis, skin aging, and its clinical significance. Methods Immunohistochemistry was used to analyze the level of Hcit in skin lesions of seborrheic keratosis (SK), unaffected skin (distant 0.5 centimeters from SK lesion), and normal skin of healthy subjects in the control group. ELISA test was used to detect the serum level of CBL in SK patients and healthy subjects of different ages. Results Hcit was mainly localized in the nucleus of epidermal cells. In healthy control skin, the expression of Hcit increased with age and showed a positive correlation with age (the correlation coefficient was 0.806, p = 0.0002). The expressional level of Hcit in SK lesions was higher than that in healthy control skin (Z = −3.703, p = 0.0002). The serum level of CBL in healthy subjects and in SK patients increased with age (the correlation coefficient were 0.5763, p = 0.0032; 0.682, p = 0.004. respectively). The serum level of CBL in SK patients was higher than that in healthy subjects (Z = −2.19, p = 0.030). Study limitations The small serum sample size in the study. Conclusion The high expressional level of Hcit is correlated with seborrheic keratosis and skin aging. HCit may be one of the potential biomarkers of skin aging.

A promising alternative for mature skin: the effects of phytoestrogens on human skin and its topical use / Alternativa promissora para peles maduras: os efeitos dos fitoestrógenos na pele humana e seu uso tópico

Skin quality deteriorates with age for various reasons, including hormone deficiencies. In women, the decline in estrogen levels during menopause plays an important role in skin degeneration, with consequent atrophy, collagen reduction, loss of elasticity, and impaired wound healing. Research has demonstrated the beneficial effects of topical phytoestrogen in preventing and repairing skin aging, with localized action and without side effects. The objective of this study was to review the relevant literature, demonstrating that this can be a safe and effective alternative for treating the skin of perimenopausal women.

A qualidade da pele deteriora-se com a idade por vários motivos, incluindo as deficiências hormonais. Nas mulheres, o declínio dos níveis de estrógeno, durante a menopausa, tem papel importante na degeneração cutânea, com consequente atrofia, redução do colágeno, perda de elasticidade e deficiência da cicatrização de feridas. Pesquisas têm demonstrado efeitos benéficos do fitoestrogênio tópico na prevenção e reparação do envelhecimento cutâneo, com ação localizada e sem efeitos colaterais. O objetivo deste estudo foi revisar a literatura pertinente ao assunto, demonstrando que esta pode ser uma alternativa segura e eficaz para o tratamento da pele de mulheres na perimenopausa.

Aplicação do ultrassom microfocado no rejuvenescimento facial: uma revisão da literatura / Application of microfocused ultrasound in facial rejuvenation: a literature review

Introdução: O aumento da expectativa média de vida leva a população a buscar, com maior frequência, tratamentos estéticos que visem o rejuvenescimento da face e do pescoço. O Ultrassom microfocado (MFU) é descrito como uma opção de tratamento não-invasiva para a flacidez facial e o envelhecimento. Objetivo: Revisar a literatura científica quanto ao uso do MFU no processo de rejuvenescimento facial e correção da flacidez da pele. Metodologia: Trata-se de uma revisão narrativa da literatura, baseada na pesquisa de artigos científicos nas bases de dados PubMed e Biblioteca Virtual em Saúde realizada durante o mês de março de 2022, através da seguinte estratégia de busca: "Microfocused Ultrasound AND Facial Rejuvenation AND Skin Laxity Treatment". Um total de 19 manuscritos foram incluídos em síntese qualitativa. Desenvolvimento: O MFU pode ser aplicado no tecido subcutâneo, produzindo pequenos pontos de coagulação térmica dentro da camada reticular média a profunda da derme e subderme. A aplicação de calor nesses discretos pontos de coagulação térmica faz com que haja neossíntese de colágeno e consequente enrijecimento da pele. Estudos recentes evidenciaramresultados promissores quanto a aplicação do MFU em regiões de sulco nasolabial, linha da mandíbula, sobrancelhas, região infraorbital, palpebra inferior e ligamentos de retenção zigomático-bucais. Considerações finais: O MFU tem se mostrado uma técnica segura, sendo considerado eficaz, não-invasiva, bem tolerada pelos pacientes e viável para a prática clínica médica e odontológica.

Introduction: The increase in average life expectancy leads the population to seek, with greater frequency, aesthetic treatments aimed at rejuvenating the face and neck. Microfocused ultrasound (MFU) is described as a non-invasive treatment option for facial sagging and aging. Objective: To review the scientific literature regarding the use of MFU in the process of facial rejuvenation and correction of sagging skin. Methodology: This is a narrative review of the literature, based on the search for scientific articles in the PubMed and Virtual Health Library databases carried out during the month of March 2022, using the following search strategy: "Microfocused Ultrasound AND Facial Rejuvenation AND Skin Laxity Treatment". A total of 19 manuscripts were included in a qualitative synthesis. Development: MFU can be applied to the subcutaneous tissue, producing small points of thermal coagulation within the middle to deep reticular layer of the dermis and subdermis. The application of heat to these discrete points of thermal coagulation causes collagen neosynthesis and consequent skin tightening. Recent studies have shown promising results regarding the application of MFU in regions of the nasolabial sulcus, jaw line, eyebrows, infraorbital region, lower eyelid and zygomatic-buccal retention ligaments. Final considerations: MFU has been shown to be a safe technique, being considered effective, non-invasive, well tolerated by patients and viable for clinical medical and dental practice.

Neuromuscular Electrical Stimulation in Facial Aging: an Integrative Literature Review / Estimulación Eléctrica Neuromuscular en el Envejecimiento Facial: Revisión Integradora della Literatura / Estimulação Elétrica Neuromuscular no Envelhecimento Facial: uma Revisão Integrativa da Literatura

ABSTRACT Despite of being a natural physiological process, aging is considered a degenerative process with evident effects on aging skin, such as reduced elasticity, wrinkles, reduced facial fat and muscle tone, sagging, changes in facial contour, and sarcopenia on the face. These changes can generate social stigma, suffering, and psychological discomfort for the patient. Thus, this study aimed to evaluate the effectiveness of Neuromuscular Electrical Stimulation (NMES), a technique used in physical therapy for muscle training, in attenuating the signs of facial aging. For this purpose, a scientific survey of publications indexed on the Medline (PubMed), CINAHL, Embase, PEDro, Lilacs, ERIC, Scopus, Web of Science, and Google Scholar databases was conducted and, based on pre-established criteria, two relevant publications for the topic were selected for discussion. The scientific literature regarding the use of NMES to attenuate the signs of aging is still very scarce. The survey showed the need to discuss the current state of knowledge. Our results suggest that, theoretically, NMES could be a promising method to attenuate the signs of aging; however, there are still no conclusive results regarding the clinical effectiveness of using NMES in the facial muscles since few studies relate NMES to facial rejuvenation. More studies are needed, with greater methodological rigor and low level of bias, using precise techniques in the evaluation and allowing to interpret with greater scientific commitment of the physiological mechanism of the muscular stimulus and its interrelation with the integumentary system, proving its effectiveness in the improvement of skin appearance.

RESUMEN El envejecimiento es un proceso fisiológico natural, aunque se considera un proceso degenerativo. Sus efectos son evidentes en la piel envejecida, que presenta disminución de la elasticidad, grasa y tono muscular, así como arrugas, flacidez, cambios de contorno y sarcopenia. Estos cambios pueden generar un estigma social y malestar psicológico para el portador. En ese contexto, el objetivo de este estudio fue evaluar la efectividad del uso de la estimulación eléctrica neuromuscular (NMES), una técnica utilizada en Fisioterapia de entrenamiento muscular para atenuar los signos del envejecimiento facial. Para ello, se realizó un relevamiento de las publicaciones indexadas en las plataformas MEDLINE (PubMed), CINAHL, Embase, PEDro, LILACS, ERIC, Scopus, Web of Science y Google Scholar, y, con base en criterios preestablecidos, se seleccionaron dos publicaciones relevantes sobre el tema. La literatura científica sobre el uso de NMES en la atenuación de los signos del envejecimiento es aún escasa. La búsqueda reveló la necesidad de una discusión sobre el estado actual del conocimiento. Los resultados de esta revisión sugieren que la NMES puede ser un método prometedor de entrenamiento muscular cuando se aplica para atenuar los signos del envejecimiento. Sin embargo, todavía hay poca evidencia con respecto a la efectividad de NMES en los músculos faciales, ya que pocos estudios relacionan NMES con el rejuvenecimiento facial. Son necesarios estudios con mayor rigor metodológico para minimizar sesgos y el uso de técnicas de evaluación precisas, que permitan dilucidar el mecanismo fisiológico del estímulo muscular y su interrelación con el sistema tegumentario y que permitan probar la eficacia de la NMES en la mejora del aspecto de la piel del rostro.

RESUMO Embora seja um processo fisiológico natural, o envelhecimento é considerado degenerativo. Seus efeitos são evidentes na pele envelhecida, que apresenta redução de elasticidade, gordura e tônus muscular, assim como rugas, flacidez, alteração de contornos e sarcopenia. Tais mudanças podem gerar um estigma social e desconforto psicológico para o seu portador. Nesse contexto, objetivou-se avaliar a eficácia do uso da estimulação elétrica neuromuscular (EENM), uma técnica utilizada na Fisioterapia para o treinamento muscular, visando à atenuação dos sinais do envelhecimento facial. Para isso, foi realizado um levantamento de publicações indexadas nas plataformas MEDLINE (PubMed), CINAHL, Embase, PEDro, LILACS, ERIC, Scopus, Web of Science e Google Scholar e, a partir de critérios preestabelecidos, foram selecionadas duas publicações relevantes sobre o tema. A literatura científica sobre o uso da EENM na atenuação dos sinais do envelhecimento ainda é escassa. O levantamento revelou a necessidade de uma discussão a respeito do estado atual do conhecimento. Os resultados desta revisão sugerem que a EENM pode ser um método promissor de treinamento muscular quando aplicado à atenuação dos sinais de envelhecimento. Contudo, ainda há poucas evidências quanto à eficácia da EENM na musculatura da face, visto que poucos estudos relacionam a EENM ao rejuvenescimento facial. São necessários estudos com maior rigor metodológico, a fim de minimizar vieses, e utilização de técnicas precisas de avaliação, permitindo a elucidação do mecanismo fisiológico do estímulo muscular e sua inter-relação com o sistema tegumentar e possibilitando a comprovação da eficácia da EENM na melhoria da aparência da pele facial.

Introducción: Al ocupar la piel una posición de frontera con el mundo exterior y ser un órgano sensible a agresiones ambientales crónicas, es preciso el conocimiento detallado de los cambios que se producen en ella con el paso de los años, para manejar de manera adecuada los procesos relacionados con su envejecimiento. Objetivo: Caracterizar la dermis papilar sana, en pacientes de diferentes edades y sexo, al tener en cuenta indicadores morfométricos. Métodos: Se realizó un estudio de una serie de casos constituida por 12 pacientes con carcinoma basocelular, diagnóstico confirmado por el servicio de Anatomía Patológica del Hospital Provincial Vladimir Ilich Lenin, a los que se les realizó biopsia escisional de la lesión y de márgenes anchos de piel sana alrededor de la misma. La densidad de área de células y de matriz extracelular amorfa de la dermis papilar sana fueron los indicadores morfométricos estudiados. Resultados: En el estudio cualitativo de la dermis papilar, se observaron con menor frecuencia los núcleos de fibroblastos que en los patrones de piel joven y de forma general, la matriz extracelular mostró una mayor densidad. En la morfometría se precisó que en la dermis estudiada existe una disminución de la celularidad y de la sustancia amorfa. Conclusiones: La densidad del área de células tiende a decrecer con la edad y fue de manera significativa diferente entre los sexos, mayor en el sexo femenino. La densidad de área de sustancia amorfa decrece; en el sexo masculino con el paso de los años, mientras que en el sexo femenino, no mostró diferencias significativas.

Introduction: As the skin occupies a frontier position with the outside world and it is an organ sensitive to chronic environmental aggressions, detailed knowledge of the changes that occur in it over the years is necessary to adequately manage the related processes with its aging. Objective: To characterize the healthy papillary dermis, in patients of different ages and sex, taking into account morphometric indicators. Methods: A study of a series of cases was carried out, it consisted of 12 patients with basal cell carcinoma, a diagnosis confirmed by the Pathological Anatomy service of the Vladimir Ilich Lenin Provincial Hospital, the patients underwent excisional biopsy of the lesion and wide margins of healthy skin around it. Cell area density and amorphous extracellular matrix of the healthy papillary dermis were the morphometric indicators studied. Results: In the qualitative study of the papillary dermis, fibroblast nuclei were observed less frequently than in young skin patterns, and in general, the extracellular matrix showed a higher density. In the morphometry, it was specified that in the dermis studied there is a decrease in cellularity and amorphous substance. Conclusions: Cell area density tends to decrease with age and was significantly different between the sexes, being higher in females. The areal density of amorphous substance decreases; in the male sex over the years, while in the female sex, it did not show significant differences.

Biotransformed soybean cream as a new nutraceutical for skin care: collagen stimulation in vitro and ex vivo

Treatments that attenuate the effects of hypoestrogenism in menopausal women have been gaining visibility. This study investigated the skin response to a phytoestrogen-enriched cosmetic formulation created by incorporating a biotransformed soybean extract (BE) into a cream-like matrix. Collagen-I expression was analyzed both in vitro (fibroblast cells) and ex vivo (skin explants). The results revealed an increased amount of collagen-I both in fibroblasts and human skin when treated with BE and BE-incorporated cream. Also, this collagen-I overexpression was inhibited by PHTPP, indicating a dependence on estrogen hormone receptor beta (ERβ) signaling. Moreover, BE was not harmful to skin microbiota, showing a promising nutricosmetic potential. Thus, this work presented a fully functional cream-like formulation that was shown to be safe and effectively increase collagen-I levels both in vitro and ex vivo.

Caracterización morfométrica nuclear de la epidermis sana en pacientes de diferentes edades y sexo

Introducción : La piel es un órgano complejo altamente vulnerable al envejecimiento, fenómeno que biológicamente provoca cambios a nivel tisular y celular. De manera usual los elementos histológicos que la caracterizan se describen con un enfoque cualitativo, sin tener en cuenta la edad, sin embargo, desde el punto de vista cuantitativo, aspecto este que lo posibilita la morfometría no ha sido abordado en todas sus potencialidades. Objetivo : Caracterizar el comportamiento de indicadores morfométricos como perímetro, área, volumen nuclear en las células de la capa espinosa de la epidermis sana, según edad y sexo. Métodos : Se realizó un estudio de serie de casos con 12 pacientes con diagnóstico histopatológico de carcinoma basocelular atendidos en Centro Oncológico del Hospital Provincial Universitario Vladimir Ilich Lenin de Holguín, en el año 2019 y a los cuales se les extirpó el tumor mediante una biopsia escisional que incluía la lesión y un borde amplio de piel sana. Se emplearon métodos teóricos y empíricos, estos últimos basados en técnicas morfométricas, luego se realizó análisis estadísticos de los datos obtenidos y se reflejaron en tablas. Resultados : A medida que avanza la edad el perímetro, el área y el volumen nuclear disminuyen en ambos sexos. Conclusiones : Tanto el perímetro, como el área y el volumen nuclear disminuyen en las células de la capa espinosa de la epidermis sana en ambos sexos a medida que avanza la edad, lo que traduce disminución del tamaño nuclear.

Introduction: The skin is a complex organ highly vulnerable to aging, a phenomenon that biologically causes changes at the tissue and cellular level. Usually the histological elements that characterize it are described with a qualitative approach, without taken age into account, however from the quantitative point of view, this aspect that morphometry makes possible has not been addressed in all its potentialities. Objective: To characterize the behavior of morphometric indicators such as perimeter, area, nuclear volume in the cells of the spinous layer of the healthy epidermis, according to age and sex. Methods: A case series study was carried out with 12 patients diagnosed with histopathology of basal cell carcinoma treated at the Oncology Center of the Provincial University Hospital Vladimir Ilich Lenin of Holguin, in the year 2019 and to which the tumor was removed by means of an excisional biopsy that included the lesion and a broad border of healthy skin. Theoretical and empirical methods were used, the latter based on techniques morphometric, then statistical analysis of the data obtained was performed and were reflected in tables. Results: As age advances the nuclear perimeter, area, and volume decreased in both sexes. Conclusions: Both the perimeter, the area and the nuclear volume decrease in the cell of the spinous layer of the healthy epidermis in both sexes as age advances, which translates into a decrease in nuclear size.

Collagen peptides against chronological skin aging: mechanisms of action and related clinical studies / 中华皮肤科杂志

In recent years, collagen peptides (CP) have become a research hotspot in delaying chronological skin aging. Animal experiments have shown that CP can repair chronologically aged animal skin by promoting collagen synthesis, inhibiting collagen degradation, and increasing antioxidant enzyme activity. Cell experiments showed that CP can promote proliferation of fibroblasts and synthesis of collagen and elastin by stimulating nuclear factor-κB signaling pathway and transforming growth factor-β/drosophila mothers against decapentaplegic signaling pathway. Clinical studies have demonstrated that long-term oral supplement with CP or CP in combination with other antioxidant active substances can increase the skin moisture content and reduce transepidermal water loss, improve skin wrinkles and elasticity, as well as improve the skin collagen fiber structure, dermal and epidermal quality and the overall condition of facial skin. This review summarizes recent studies on mechanisms underlying chronological skin aging and mechanisms of action of CP in repairing chronologically aged skin, in order to provide a theoretical basis for further clinical research into and application of CP in repairing chronologically aged skin.

UVB irradiation differential regulate miRNAs expression in skin photoaging

Abstract Background: UVB irradiation can cause acute damage such as sunburn, or photoaging and melanoma, all of which are major health threats. Objective: This study was designed to investigate the mechanism of skin photoaging induced by UVB radiation in mice through the analysis of the differential expression of miRNAs. Methods: A UVB irradiation photoaging model was constructed. HE and Masson special stains were used to examine the modifications in the epidermis and dermis of mice. The miRNA expression profiles of the mouse skin model exposed to UVB radiation and the normal skin of mice were analyzed using miRNA-sequence analysis. GO and Pathway analysis were employed for the prediction of miRNA targets. Results: A total of 23 miRNAs were evaluated for significantly different expressions in comparison to normal skin. Among them, 7 miRNAs were up-regulated and 16 were down-regulated in the skin with photoaging of mice exposed to UVB irradiation. The differential expression of miRNA is related to a variety of signal transduction pathways, among which mmu-miR-195a-5p and mitogen-activated protein kinase (MAPK) signal pathways are crucial. There was a significant differential expression of miRNA in the skin of normal mice in comparison with the skin with photoaging induced by UVB irradiation. Study limitations: Due to time and energy constraints, the specific protein level verification, MAPK pathway exploration, and miR-195a-5p downstream molecular mechanism need to be further studied in the future. Conclusions: UVB-induced skin photoaging can be diagnosed and treated using miRNA.

Introduction: Cutaneous xerosis presents a high frequency and can generate, in addition to discomfort, changes in the visual and sensory appearance of the skin, as well as an increased risk of injury occurrence. Upon instituting systematic and daily examination, it is possible to contribute to injury prevention by identifying risks. Objective: To map the scientific evidence on conditions related to the risk of injury occurrence in elderly people with cutaneous xerosis in the hospital setting. Methods: This is a literature review using the PRISMA tool (Preferred Reporting Items for Systematic Review and Meta-Analyses). The search for studies was carried out in September and October 2020. Articles published in English, Portuguese or Spanish within the last ten years were reviewed, combining the following descriptors and keywords with each other by the Boolean operator AND: piel seca [dry skin], envejecimiento de la piel [skin aging], enfermería [nursing], cuidado de enfermería [nursing care], and cuidados del anciano [elderly care]. Conclusions: A total of thirteen studies made up the corpus, through which the following conditions were found in the national and international literature: presence of areas with altered sensitivity and hydrogen potential, lower turgor and elasticity, immobility, high-age group, pruritus, skin cracking, friction and shearing, as well as the presence of concomitant diseases. It was possible to map the main conditions related to the risk of occurrence of lesions in the elderly people with cutaneous xerosis in the hospital setting, as well as to highlight the need for interventions by nurses to prevent the occurrence of lesions, without forgetting the contributions of the interprofessional team, because the problem has multifactorial causes(AU)

Pattern of dermatoses in the elderly population attending the dermatology clinic at a Tertiary Care Center in South-East Rajasthan

Introduction: The skin acts as the first line of defense for the body against external injuries. With aging, the architecture of the skin undergoes intrinsic changes that impair its capacity for repair. In addition, the aging skin is more susceptible to injury by external stimuli, including ultraviolet rays and environmental pollutants. The combination of these factors predisposes the elderly to a variety of dermatological disorders, including xerosis, pruritus, photoaging, eczematous disorders, and tumors. The elderly (>60 years of age) population in India accounted for 8.6% (104 million) in 2011, and the figure has been projected to increase to 19% by the year 2050. It is imperative to identify the pattern of cutaneous disorders in this population as skin care regimens aimed to improve epidermal function have been shown to be effective inthe prevention and treatment of some of these aging-associated cutaneous disorders. Objectives: The objective of the study was to identify the pattern of dermatoses among the elderly population attending the dermatology clinic at a tertiary care hospital in South?east Rajasthan. Materials and Methods: We conducted a cross-sectional descriptive study of patients above the age of 60 years who attended the dermatology clinic at a tertiary care hospital in South?east Rajasthan from May 2018 to May 2020. A combination of history, physical examination, and clinical investigations (when appropriate) were used to establish the diagnosis. Results: A total of 210 patients were included in this study. Most patients were between the age group of 60–65 years (40.47%). One hundred and thirty?eight were male (65.71%) and 72 were female (34.28%), with a male to female ratio of 1.9:1. Our study demonstrated that xerosis was one of the most common diagnoses seen in 126 cases (60%), followed by eczematous skin conditions seen in 82 cases (39%). Conclusion: The elderly constitute an important part of the population. Cutaneous disorders in the elderly range from mild disorders such as cherry angiomas to dermatological malignancies. Therefore, it is important to recognize the pattern of dermatosis in this population so that appropriate therapeutic and preventive strategies could be implemented.

Efficacy of sunscreen with photolyase or regular sunscreen associated with topical antioxidants in treating advanced photodamage and cutaneous field cancerization: a randomized clinical trial

Abstract Background Several treatments are available for skin with advanced photodamage, which is characterized by the presence of actinic keratoses (AK). Objectives Evaluate the efficacy of using sunscreen with photolyase compared to regular sunscreen, as well as to compare the combination of a topical formulation of antioxidants versus placebo in the treatment of advanced photodamage. Methods This was a randomized, double-blind, factorial clinical trial. Participants with AKs on their forearms were randomized to apply regular sunscreen (SC) or sunscreen with photolyase (SC+P) on both forearms during the day. One of the forearms in each group was randomized again to receive topical antioxidants (AOx), and the other forearm received a placebo cream (both for night application). The four groups were SC/AOx, SC/placebo, SC+P/AOx, and SC+P/placebo. The duration of treatment was 8 weeks. Primary outcomes were total AK clearance, decrease in Forearm Photoaging Scale (FPS), and AK severity scores. Secondary outcomes were reduction in AK count, partial clearance rate, and safety. Results Forty participants (80 forearms) were included. All groups showed significant improvement in outcomes at week eight. There were no significant differences between SC and SC+P for either outcome. AOx led to a significant reduction in AK count (22%; p < 0.05). Partial clearance was obtained in 18 (47.4%) forearms treated with AOx and in 9 (23.7%) treated with placebo (p < 0.05). All groups reduced the FPS score, without significant differences among them. Conclusions There is no difference in the treatment of advanced photodamage skin when comparing the use of sunscreen with photolyase and regular sunscreen, and topical antioxidants were more efficient in reducing AK count than placebo. Study limitations Short interval of follow-up and absence of re-evaluation in the absence of treatment were limitations of the present study.

Fotoenvejecimiento cutáneo y su relación con el cáncer de piel: revisión sistemática / Cutaneous photoaging and its association with skin cancer: a systematic review

Introducción. Un factor fundamental en el envejecimiento de la piel es la exposición acumulativa a la luz solar. Al avanzar el proceso de fotoenvejecimiento, el colágeno y las fibras elásticas experimentan mayores daños, generando patologías asociadas a cáncer. Se plantea como objetivo de esta revisión, analizar la evidencia que existe en relación a las diferentes situaciones del fotoenvejecimiento cutáneo y su asociación con el cáncer de piel. Metodología. Se elaboró una revisión sistemática, exploratoria, a través de una búsqueda bibliográfica en gestores de bases de datos en salud. Se seleccionaron 18 artículos completos entre los años 2019 y 2020. Resultados. Se agruparon los hallazgos de los artículos en dos matrices de información, la primera que indica los temas principales del fotoenvejecimiento y la relación con los factores asociados a cáncer de piel, y una segunda matriz que presenta la interrelación de la asociación con la conclusión más relevante del artículo. Conclusiones. El fotoenvejecimiento es un problema que crece día a día impactando en la vida del ser humano, creando repercusiones a nivel físico y mental que afectan la calidad de vida. Es necesario crear conciencia acerca de los mecanismos de fotoprotección, como el uso de bloqueadores solares, antioxidantes, evitar la luz solar y uso de lentes solares, entre otros; y, en los casos que ya exista algún daño por fotoenvejecimiento, elegir la mejor alternativa e individualizar cada paciente según su tipo de piel y enfermedades asociadas con la edad, para un mejor enfoque de tratamiento, y así impactar de manera positiva en el crecimiento exponencial que existe hoy en día en diversos tipos de cáncer de piel y lesiones precancerosas

Introduction. A fundamental factor in skin aging is cumulative exposure to sunlight. As the photoaging process progresses, collagen and elastic fibers experience greater damage, generating pathologies associated with cancer. The aim of this review is to analyze the evidence that exists in relation to the different situations of cutaneous photoaging and its association with skin cancer. Methodology. A systematic, exploratory review was prepared through a bibliographic search in database managers in health. A total of 18 articles were selected between the years 2019 and 2020. Results. The articles information were grouped into two matrix, the first one that indicates the main themes of photoaging and the relationship with the factors associated with skin cancer, and a second matrix that presents the interrelationship of these factors with the most relevant conclusion of the study. Conclusions. Photoaging is a problem that grows day by day impacting on human life, creating repercussions on a physical and mental level affecting the quality of life. It is necessary to raise awareness about photoprotection mechanisms such as the use of sunscreen, antioxidants , avoid sunlight, use of solar lenses, among others; and in cases where there is already some damage caused by photoaging, choose the best alternative and individualize each patient according to their skin type and diseases associated with age, for a better treatment approach, and thus positively impact the exponential growth that exists today in various types of skin cancer and precancerous lesions
