Consumer Preferences of Topical Vitamin C Products: A Comparative Study.

Hyperpigmentation disorders greatly impact the quality of life of many patients. Vitamin C and ascorbic acid derivatives are commonly used as topical agents to reduce the effect of facial dyschromia. The market for vitamin C topicals has greatly increased, but with little oversight, resulting in a wide variety of products with regard to purity and efficacy. In this study, we conducted an analysis of the most highly rated vitamin C-containing compounds on Amazon and Sephora. It was found that consumers for both retailers prioritized efficacy and cosmetic elegance in their rating of products. Additionally, consumers displayed no preference among vitamin C derivatives in the products available to them. This study highlights the diverse vitamin C formulations currently available as well as consumer preferences, emphasizing the importance of fully reviewing all products patients are utilizing to better counsel on treatment regimens.

Contrasting Social Media Use Between Young Adults With Inflammatory Bowel Disease and Type 1 Diabetes: Cross-sectional Study.

BACKGROUND: Social media is used by young adult patients for social connection and self-identification. OBJECTIVE: This study aims to compare the social media habits of young adults with inflammatory bowel disease (IBD) and type 1 diabetes (T1D). METHODS: This is a cross-sectional study of subjects from Boston Children's Hospital outpatient IBD and diabetes clinics. Patients above 18 years of age were invited to complete a brief anonymous survey, which asked about the various ways they use several social media platforms. RESULTS: Responses were received from 108 patients (92.5% response rate), evenly split across disease type. We found that 83% of participants spent at least 30 minutes per day on social media, most commonly on Instagram and Facebook. Although the content varied based on the platform, patients with IBD posted or shared content related to their disease significantly less than those with T1D (23% vs 38%, P=.02). Among Instagram users, patients with IBD were less likely to engage with support groups (22% vs 56%, P=.04). Among Twitter users, patients with IBD were less likely to seek disease information (77% vs 29%, P=.005). Among Facebook users, patients with IBD were less likely to post about research and clinical trials (31% vs 65%, P=.04) or for information seeking (49% vs 87%, P=.003). Patients with IBD were also less likely to share their diagnosis with friends or family in person. CONCLUSIONS: Young adults with IBD were less willing to share their diagnosis and post about or explore the disease on social media compared to those with T1D. This could lead to a sense of isolation and should be further explored.

Impact of Direct-to-Consumer Advertising of Cosmetic Procedures on Consumers.

BACKGROUND: Direct-to-consumer (DTC) advertising is a prominent type of health care communication. OBJECTIVE: This study aims to determine the impact of DTC advertisements on consumer opinion. METHODS: A total of 203 participants were recruited from dermatology clinics at an urban academic center. Participants viewed 2 cosmetically oriented DTC advertisements, and prequestionnaires and postquestionnaires were administered to assess consumer opinion. RESULTS: Postquestionnaire data highlight a 18.8% and 24.6% increase in participants reporting using commercials as an information source (p < .001) and seeking out additional medical knowledge (p < .001), respectively. After watching the advertisements, there was a 14.4% increase in participants who believed advertisements facilitate better discussions between patients and physicians (p < .001) and a 33% increase in patients reporting they would discuss the procedures with their doctors (p < .001). Of the participants, 60% believed the advertisements did not provide enough information about the possible risks of the product and 39.4% believed a physician was not required to perform cosmetic procedures. CONCLUSION: Direct-to-consumer advertisements instill meaningful information to patients and promote patient-physician communication. They also seem to exaggerate the benefits while making the procedures seem simple and without risks, suggesting trained medical professionals are not needed for administration.

Characteristics of keratinocyte carcinomas in Hispanics compared to non-Hispanic whites: A retrospective 5-year study.

BACKGROUND: Hispanics are one of the fastest growing populations in the United States. Few studies have characterized the patterns of keratinocyte carcinoma presentation in Hispanics. OBJECTIVE: The study aimed to compare the clinical and histologic characteristics of keratinocyte carcinomas in Hispanics and non-Hispanic whites. MATERIALS AND METHODS: A five-year retrospective chart review was conducted at a single academic center to identify all histologically-confirmed cases of keratinocyte carcinomas. Tumor characteristics were then compared between Hispanics and non-Hispanic whites. RESULTS: A total of 197 tumors were identified of which 76% occurred in non-Hispanic whites and 24% in Hispanics. Tumor diameter was not larger and histologic subtype was not more aggressive in Hispanics compared to non-Hispanic whites. Age of diagnosis of basal cell carcinoma was younger among Hispanics compared to non-Hispanic whites (P < .05). CONCLUSION: Hispanics were not more likely to present with more high-risk keratinocyte carcinomas compared to non-Hispanic whites in terms of tumor diameter, differentiation and subtype.

Evolving beauty-Creating and transforming inequalities.

Society has always been fascinated by beauty, an interest that has a psychological and evolutionary basis. Studies across various fields have shown that being beautiful can result in emotional well-being and privilege in one's career and personal life. However, beauty is not equally distributed in our society, leading people to pursue aesthetic treatments and procedures to meet the beauty standard. Over time and with the influence of media, the societally accepted beauty standard has evolved. It is essential for clinicians to be aware of societal implications of beauty as they may serve as a motivation for patients seeking cosmetic procedures.

Melasma pathogenesis: a review of the latest research, pathological findings, and investigational therapies.

Melasma is an acquired hyperpigmentation disorder most commonly affecting females with darker skin types. It is triggered by several factors including sun exposure, genetic influences, and female sex hormones. The pathology of melasma extends beyond melanocytes and recent literature points to interactions between keratinocytes, mast cells, gene regulation abnormalities, neovascularization, and disruption of basement membrane. This complex pathogenesis makes melasma difficult to target and likely to recur post treatment. A better understanding of the latest pathological findings is key to developing novel and successful treatment options. This review aims to provide a summary of the more novel pathological findings and latest investigational therapies.

Willingness-to-pay and Time Trade-off: The Burden of Disease in Patients with Benign Hyperpigmentation.

Objective: We assessed willingness-to-pay (WTP) and time trade-off (TTO) as methods to quantify the disease burden of benign hyperpigmentation. Design: This was a cross-sectional pilot study that included 85 adults. A paper survey was used to collect demographic and health utility information; an accompanying dermatological exam assessed disease severity. Setting: This was a single-site study performed at an urban dermatology clinic. Participants: Adults 18 years of age or older who spoke English, Spanish, or Portuguese were included. Measurements: Utility measures included WTP, TTO, and time spent concealing the condition; correlation with quality of life was also assessed. Results: Mean WTP for 25-percent improvement (WTP25) of the skin condition was $38.95; for a 50-percent improvement (WTP50), $83.18. Participants were willing to give up 1.4 hours per day to receive a therapy that would completely cure their condition. The average proportion of monthly income that participants were willing to spend on a therapy that could cure their condition was 13.3 percent. Daily concealment time was, on average, 20.8 minutes, which correlated with a worsened quality of life. Conclusion: Disease burden was high, overall, for benign hyperpigmentation conditions. Health utilities offer a patient-centered method of assessing impact on quality of life.

Sexual dimorphism and transgender medicine: appealing to a viewer's sense of beauty.

Sexual dimorphism - the phenotypic structural differences between male and female faces - has been shown to be an important universal component of beauty. This concept plays a key role in facial feminization surgery (FFS), which consists of contouring and reshaping features of the skull itself to alter the foundation of the face. FFS has been shown to improve quality of life among transgender women and therefore an understanding of the procedure and the concept of sexual dimorphism is key for plastic surgeons, dermatologists, and other healthcare providers.

Effect of stimuli on sun protective habits: A randomized double-blind controlled study.

BACKGROUND: Visual imagery has been shown to improve adherence to health messages but has scarcely been investigated in sun protection campaigns. OBJECTIVE: To determine the effectiveness of pictorial- and textual-based sun protective messages in a largely Hispanic population. METHODS: One hundred and forty-five participants received standard of care (SOC) as defined as sun protective counseling and were then randomized to receive either (a) images of sun damage, (b) a textual pamphlet about sun damage, or (c) no further messages. Analysis-of-variance tests for repeated measures were used to estimate the effects of the different stimuli on participants' knowledge and intention to sun protect. RESULTS: All stimulus groups demonstrated an improvement in perceived effectiveness of sun protective habits (p < 0.05). However, pictorial and textual stimuli were both more effective than SOC in improving intentions to sun protect (p < 0.05), but there was no differential effect between the two. CONCLUSIONS: Both pictorial and textual stimuli were more effective than SOC in improving intentions to sun protect, but there was no differential effect between the two.

Appearance-based vs health-based sun protective messages: A randomized, double-blind controlled study.

BACKGROUND: Appearance-based messages have shown promise in improving sun protection habits among Caucasians but have scarcely been investigated in Hispanic populations. OBJECTIVE: To compare the effectiveness of appearance-based vs health-based messages in an ethnic patient population, where hyperpigmentation disorders are prevalent and often cosmetically concerning. METHODS: One hundred thirty-seven patients were randomized to receive images of (a) skin cancer, (b) hyperpigmentation, or (c) wrinkles. Analysis of variance tests for repeated measures were used to estimate the effects of the different stimuli on participants' knowledge and intention to sun protect. RESULTS: Appearance-based interventions were more effective in improving intentions to sun protect among both Hispanics and non-Hispanic Whites (P < 0.05). They were furthermore more effective among younger patient populations (≤40 years old) and patients who thought that a tanned appearance is attractive (P < 0.05). CONCLUSIONS: Appearance-based photos of sun damage were more effective than health-based messages among Hispanics, younger patient populations, and those who find tanned appearances to be attractive.
