RESUMO
INTRODUCTION: An increasing interest in minimally invasive procedures hassled to a demand for an effective local anesthetic algorithm. The scalp presents a challenge in achieving effective anesthesia due to the presence of hair shafts. This study aims to evaluate the efficacy of different methods during a microneedling procedure, including 25 mg lidocaine and 25 mg prilocaine cream, skin spray with 10% lidocaine, and cold gel compresses. MATERIALS AND METHODS: Sixty-two men aged between 20 and 50 years underwent three microneedling treatments, each using a different method of anesthesia. The treatment area was divided into two equal parts, with one part exposed to a specific anesthetic method. Patients were asked to rate their pain on a 0-10 verbal analog scale. An attempt was made to objectify the results using algometry. RESULTS: A negative correlation was observed between the algometry results and the VAS score after the application of the cream and cold compresses. DISCUSSION: When choosing monotherapy, it is recommended to use cold gel compresses for scalp microneedling after considering the advantages and disadvantages of different methods.
RESUMO
BACKGROUND: Macular amyloidosis is a form of primary localized cutaneous amyloidosis presented by pruritic pigmented macules in rippled or reticulate pattern. The aim of this study was to assess the efficacy of using topical tranexamic acid with micro-needling comparing to micro-needling alone in patients with macular amyloidosis. MATERIALS AND METHODS: Patients with bilaterally located macular amyloidosis on trunk or upper extremities were recruited in this trial. The skin lesions in all patients were divided into two parts which were randomly assigned to the group of treatment with micro-needling plus tranexamic acid and the group of micro-needling alone. There were four sessions of treatment with 2 weeks interval. The percentage of improvement in pigmentation (based on photographs and dermoscopy) and rippling of each group was determined by three blinded dermatologists. The level of patient satisfaction and reduction of pruritus was measured by a questionnaire and defined as a percentage. RESULTS: Twenty females were enrolled in this study. The mean (SD) patients' age was 39.7 (±10.13) years. Both groups showed improvement in pigmentation based on images, dermoscopy, and rippling pattern. Patients' satisfaction was 46.5% in tranexamic acid group and 47.5% in micro-needling alone. Nevertheless, there was no significant difference between both groups (p value >0.05). Interestingly, the pruritus improved 61.66% after four sessions of treatment in both groups. CONCLUSION: Micro-needling is a suitable modality for decreasing pruritus and pigmentation in macular amyloidosis. However, topical application of tranexamic acid does not lead to additional improvement.
RESUMO
Androgenetic alopecia, the most common cause of hair loss affecting both men and women, is typically treated using pharmaceutical options, such as minoxidil and finasteride. While these medications work for many individuals, they are not suitable options for all. To date, the only non-pharmaceutical option that the United States Food and Drug Administration has cleared as a treatment for androgenetic alopecia is low-level laser therapy (LLLT). Numerous clinical trials utilizing LLLT devices of various types are available. However, a myriad of other physical treatments for this form of hair loss have been reported in the literature. This review evaluated the effectiveness of microneedling, pulsed electromagnetic field (PEMF) therapy, low-level laser therapy (LLLT), fractional laser therapy, and nonablative laser therapy for the treatment of androgenetic alopecia (AGA). It also explores the potential of multimodal treatments combining these physical therapies. The majority of evidence in the literature supports LLLT as a physical therapy for androgenetic alopecia. However, other physical treatments, such as nonablative laser treatments, and multimodal approaches, such as PEMF-LLLT, seem to have the potential to be equally or more promising and merit further exploration.
RESUMO
BACKGROUND: In treating post-traumatic scars, this study compared the safety and effectiveness of combined subcision with saline and microneedling versus combined subcision with platelet-rich plasma and microneedling. Combined subcision with saline and microneedling or combined subcision with platelet-rich plasma and microneedling were used to treat 36 consecutive individuals with post-traumatic scarring. The Modified Manchester score was used to assess texture change, pigmentation, and surface distortion changes. Each change was given a score between 1 and 4. A lower score (range: 3-12) indicates a better result. The mean of the three individual scores was determined. For best outcomes, each patient needed four treatment sessions for each scar, with a one-month follow-up period following the final treatment. The three variables in group B had mean scores of 1.4 ± 0.5, 2 ± 0.8, and 2.2 ± 0.9, respectively, for texture change, pigmentation, and surface distortion. With a mean score of 1.4 ± 0.5, texture change had the best response out of the three variables we evaluated. The investigator determined that the mean improvement score for patients in group B's overall appearance was 5.61 ± 1.19. The study has shown that the combination of subcision with platelet-rich plasma, and microneedling appears to be a promising treatment for posttraumatic scars due to its low risk and high efficacy. Our findings suggest that this is a safe method for treating posttraumatic scars, with few side effects and a low chance of recurrence. IRB LOCAL APPROVAL NUMBER: 04-2023-300279.

Introduction: Vitiligo poses a significant challenge, particularly in treatment-resistant areas such as acral regions. This study aimed to evaluate the effectiveness and safety of combining fractional CO2 laser and microneedling with conventional therapies for non-segmental vitiligo in resistant areas. Methods: A randomized clinical trial with a paired design was conducted on 84 individuals with non-segmental vitiligo and treatment-resistant lesions. Participants in two separate groups received various combinations of interventions, including narrowband ultraviolet B (NB-UVB) and topical steroid (Clobetasol ointment) as conventional treatments, with fractional CO2 laser or microneedling as add-ons for four symmetrical treatment-resistant lesions. The treatment duration was 16 weeks, followed by observation until six months post-intervention for each patient, and it focused on assessing the percentage of repigmentation, safety, patient satisfaction, and potential adverse effects. Results: The results of the study revealed a significant difference in average efficacy, with treatments involving fractional CO2 laser and microneedling compared with other interventions without them showing a higher percentage of repigmentation. No notable distinction in repigmentation patterns was observed, except for slightly higher marginal repigmentation with microneedling. Side effects, including pain, burning sensation, and erythema, were more frequent, with no significant difference between the groups. Itching and crusting had a significant difference in the two groups. Patient satisfaction levels were comparable, with the first group slightly more than the second. Conclusion: In conclusion, combining NB-UVB and topical steroid therapies with the fractional CO2 laser or microneedling seems to be effective for vitiligo treatment in resistant areas. Attention to variations in patients' characteristics and specific body locations is necessary when applying these modalities. This study provides valuable insights into novel approaches for managing vitiligo and highlights the potential benefits of these innovative treatments in combination with conventional therapy.
RESUMO
The prevalence of rosacea in skin of color (SOC) populations is estimated to be as high as 10% in some countries. Traditionally, intense pulsed light (IPL) and pulsed dye laser (PDL) have been the laser and energy-based devices (EBDs) used to treat rosacea. However, not all laser and EBDs are safe for SOC (Fitzpatrick skin types IV-VI) due to increased absorption of energy in pigmented skin and increased risk of post-inflammatory hyperpigmentation and scarring. This review summarizes the use of the top seven laser and EBDs for treating rosacea in SOC.

This study aimed to analyze the efficacy and safety of microneedling (MN), both alone and in combination with other treatments, to refine the approach for treating acne scars using MN. We systematically searched Pubmed, Cochrane Library, Embase, and Web of Science for randomized controlled trials examining MN or its combinations in patients with acne scars. All statistical analyses were performed using Stata 18 software. A total of 24 studies involving 1546 participants were included. The analysis revealed that MN combined with chemical peels (CP) exhibited the best results in terms of degree of improvement, patient satisfaction, and treatment efficacy compared to other treatments examined, including MN alone, MN with hyaluronic acid (HA), MN with botulinum toxinA (TA), MN with platelet-rich plasma (PRP), PRP alone, CP, and laser therapy. The results for MN combined with additional treatments were obviously better than for MN alone. Side effects such as erythema, pain, and post-inflammatory hyperpigmentation showed no significant differences across all treatments assessed.

Primary axillary hyperhidrosis is an idiopathic disorder that creates severe psycho-social burden due to excessive uncontrolled sweating. Various therapeutic agents have been described, but each has its own limitations. The use of fractional microneedling radiofrequency has emerged lately with promising results. This study aimed to determine the efficacy and safety of fractional microneedle radiofrequency in comparison to Botulinum toxin-A (BT-A) in patients with primary axillary hyperhidrosis. In this randomized controlled clinical trial, 20 patients (40 sides) were randomized to either fractional microneedle radiofrequency (4 sessions at 3-week intervals) or BT-A (single session), where each side received one of the treatment modalities. Efficacy was measured at 3, 6 and 12 months using Minor's starch iodine test, HDSS score, Hqol questionnaire, and patient satisfaction. Fractional microneedle radiofrequency, although showed moderate efficacy, is inferior to BT-A regarding longitudinal efficacy at 12 months, as well as patients' satisfaction. Both treatment modalities showed to be equally safe, but fractional microneedle radiofrequency procedure was substantially more painful. In conclusion, fractional microneedle radiofrequency does not offer a better substitute to BT-A in primary axillary hyperhidrosis. BT-A shows higher efficacy, is less painful, less expensive, and needs a smaller number of sessions.

BACKGROUND: The challenging management of melasma highlights the inadequacies of conventional therapies and their high risk of recurrence. Integrating microneedling for device-assisted drug delivery with tranexamic acid (TA), recognized for its melanin synthesis inhibition, presents a novel approach that warrants further investigation to fully assess its potential in enhancing melasma treatment efficacy. METHODS: Fifty moderate to severe melasma patients participated in this randomized outcome-assessor-blinded controlled trial. Patients were randomly allocated into two main groups. Group A received a modified Kligman formula on one hemi-face on alternate nights for 2 months (A1) and three sessions of microneedling with 10% topical TA on the other hemi-face at 1-month intervals (A2). Group B used the same modified Kligman formula on both sides of the face, with one side additionally receiving three sessions of microneedling with 4% TA (B1) and the opposite side with 10% TA (B2). Primary outcomes were % Modified Melasma Area and Severity Index (mMASI) and % visual analogue scale (VAS) change during 6 month follow-up. Adverse events including post-inflammatory hyperpigmentation (PIH) and treatment tolerability were recorded. RESULTS: Compared to baseline, the mean mMASI reduction immediately after the final session was higher in A1, B1, and B2 (56.84%, 50.88%, and 55.87%, respectively) than in A2, which saw only a 13.16% reduction. Efficacy notably declined after the cessation of treatment across all groups. While the efficacy within groups A1, B1, and B2 was comparable, microneedling with 4% or 10% TA combined with the topical modified Kligman formula proved more potent in patients at a lower risk of PIH. Overall, 22% of patients reported PIH, particularly in the A2 group (28% of hemi-faces), with its occurrence significantly associated with treatment during warmer seasons and in darker skin phototypes. Other adverse events were not observed in any patient. Patient satisfaction was highest in groups B1 and B2, where approximately 72% reported 'excellent' satisfaction. The lowest durability rate (16%) was observed in group A2, while the highest (72%) was seen in group B2, comparable with groups A1 and B1. Treatment tolerability was reported 100% in all groups. CONCLUSION: It was found that the modified Kligman formula outperformed microneedling-TA alone. However, with optimal patient selection, particularly targeting those at lower risk for PIH with lighter skin phototypes and scheduling treatments during less-sunny seasons, combining microneedling with 4% or 10% TA and the modified Kligman formula significantly enhanced efficacy and satisfaction rates compared to conventional topical treatment.
RESUMO
Acne scars can greatly impact patient quality of life. While treatment options have included mi- croneedling, the recent addition of platelet-rich plasma (PRP) to this regimen has led to an increased popularity of combination treatment. Here, we aimed to review the efficacy of microneedling and PRP therapies and review the literature on combination treatment for acne scars.
RESUMO
Background: The development of microfocused ultrasound and fractional radiofrequency-based devices has expanded the range of cosmetic treatment options for patients with skin of color. Fractional non-ablative laser treatments can also be safely performed in skin types III-VI with appropriate settings and adjunctive topical treatments. Objective: We sought to review the available literature on the use of energy-based devices for treatment of facial skin conditions in skin types III-VI. Methods: A PubMed search was performed on studies from 2010-2021 assessing safety and efficacy of fractional ablative and non-ablative lasers, radiofrequency, and microfocused ultrasound-based treatments for conditions such as acne scars, melasma, benign pigmented lesions, rhytids, and skin laxity in skin types III-VI. Results: Seven randomized trials, fourteen prospective cohort studies, and six retrospective reviews were included. Combination treatment with fractional radiofrequency and non-ablative laser has demonstrated efficacy in the treatment of acne scars in skin of color with minimal adverse effects. Laser-assisted drug delivery with low-density 1927-nm thulium or diode lasers has been shown to reduce the number of treatments required for significant clearance of melasma as compared with other modalities. Microfocused ultrasound has been shown to safely treat skin laxity in skin of color. Limitations: There is a paucity of studies which include patients with skin type VI, limiting our overall understanding of the safety of these treatments in skin of color. Conclusion: There are numerous available studies demonstrating safety and efficacy of energy-based devices for the treatment of facial skin conditions in skin types III-VI, but the significant variation among their designs, methods of assessment, and study populations highlights the need for larger meta-analyses to further interpret their results.
RESUMO
Background and aim The majority of acne has the potential to transform into facial scars, which have a physical and psychological effect on the individual. There are plenty of treatment options to manage such scars. The aim of this study is to assess the comparative effect of the injection of platelet-rich plasma (PRP) alone, with that of the injection of PRP with microneedling, in the reduction of atrophic facial acne scars. Methods A total of 30 participants were included in this study, divided into two groups (n = 15). Patients in Group I received intradermal injection of PRP only, and Group II included patients receiving intradermal injection of PRP with microneedling. The scar appearance was evaluated at baseline, after one, two, and three months using Goodman Baron's scar scale. The statistics were analysed using the Chi-square and Student's t-tests. Results Patients in the PRP with microneedling group had lower acne scar scores on the Goodman Baron scale compared to those who received only PRP. The acne scores were statistically significant (p-value < 0.05) in the second and third months of treatment in Group II. Conclusion The addition of microneedling to PRP has proven to be effective in the reduction of facial acne scars. However, different types of scars require different modalities of treatment, and the final decision lies in the hands of the operator and the requirements of the patients.
RESUMO
We aimed to determine the efficacy of the various available oral, topical, and procedural treatment options for hair loss in individuals with androgenic alopecia. Using the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines, a systematic review of the National Library of Medicine was performed. Overall, 141 unique studies met our inclusion criteria. We demonstrate that many over the counter (e.g. topical minoxidil, supplements, low-level light treatment), prescription (e.g. oral minoxidil, finasteride, dutasteride), and procedural (e.g. platelet-rich plasma, fractionated lasers, hair transplantation) treatments successfully promote hair growth, highlighting the superiority of a multifaceted and individualized approach to management.

BACKGROUND: TikTok is one of the fastest-growing social media platform, and its short-form videos have become a widely used source of health information. "Dermarolling" is a form of roller microneedling often practiced at home, and patients may be using TikTok to inform their decision to pursue this treatment and their practice of it. AIMS: This study assessed the informational content quality, source, and engagement of TikTok dermarolling videos to highlight potentially harmful social media trends. METHODS: On a predetermined date, "dermarolling" was searched on TikTok. The top 75 results were screened. Number of views, creator type, type of video, and whether risks were discussed were recorded. Information quality was assessed using the DISCERN tool. The data were stratified by creator type, and statistical analysis was performed using R version 4.3.2. Median viewership and DISCERN scores were compared using Kruskal-Wallis tests with post hoc pairwise Wilcoxon tests. Fisher's exact test was used to compare rates of risk discussion between groups. RESULTS: Sixty-one of the reviewed videos met the inclusion criteria. Influencer videos engaged the largest overall audience and had higher median viewership than other creators. Physicians, primarily dermatologists, created exclusively educational content and influencers created mostly experience-based content. Overall content quality was generally low-moderate, with a median (IQR) DISCERN score of 30.5 (26.5-33.5). Physician content had higher median DISCERN scores than influencers (p = 0.004) and others (p = 0.004). Physicians were more likely to discuss risks compared to influencers (p = 0.02). CONCLUSIONS: TikTok content on "dermarolling" was of relatively low quality, and nonphysicians command a large viewership. Physician-created content is often of higher informational quality, and dermatologists should escalate their efforts to engage patients in this space to mitigate the effects of potential misinformation.

Background: Vitiligo is an inveterate disease of great aesthetic concern presenting with depigmented macules and patches. It is often incorrigible to medical treatment. Aim: To study the clinical profile of vitiligo patients and evaluate the effect of 5% 5-fluorouracil (5-FU) cream with microneedling. Materials and Methods: This observational analytical study was conducted from November 2019 to July 2021. A total of 33 adult vitiligo patients were treated with oral mini-pulse (dexamethasone) therapy and topical corticosteroid (clobetasol propionate 0.05%). Patient's total number of vitiligo lesions with <10-cm size were counted and half of the lesions were treated with 5-FU + microneedling (Group A), while a remaining number of lesions were not treated with 5-FU + microneedling (Group B). In the case of the odd number of lesions, the total number of lesions minus one was considered and then divided into equal numbers for treatment. The procedure was performed every 2 weeks for 3 months. Clinical improvement was assessed monthly till 6 months by serial clinical photographs and grading scores. Results: Initiation of repigmentation started in the first month in Group A, whereas in Group B, it was seen in the second, which was statistically significant (P < 0.0001). Excellent improvement (>75% repigmentation) was noted in Group A as compared to Group B at the end of 6 months (P < 0.0001). Conclusions: Needling with 5% 5-FU appears to be a simple, safe, and effective treatment in vitiligo. It can be used in poor responders to conventional therapy.
RESUMO
BACKGROUND: Gingival inflammation, a hallmark of periodontal diseases, serves as a critical focus in oral health research. Characterized by redness, swelling, and bleeding of the gingival tissues, it reflects the body's response to bacterial biofilms accumulating on the tooth surfaces. This inflammatory process, initiated by the interaction between oral bacteria and the host immune system, can lead to a spectrum of periodontal conditions ranging from mild gingivitis to severe periodontitis. Understanding the efficacy of various methods to treat gingival inflammation is essential for refining treatment strategies and enhancing patient satisfaction in the realm of gingival inflammation. AIM: The objective of the study was to evaluate the efficacy of employing the microneedling technique with olive oil on gingival inflammation and plaque accumulation in individuals with gingivitis. Materials and methods:Twenty-four individuals diagnosed with plaque-induced gingivitis were selected from Saveetha Dental College, Chennai. Participants were randomly assigned to one of two groups: Group A, comprising 12 individuals who received mechanical periodontal treatment only and Group B, consisting of 12 individuals treated with dermapen and topical olive oil. This involved the creation of microholes in the gingival tissue to enhance the concentration and penetration of the oils through the gingival tissues. Post-intervention assessments of gingival and plaque status were conducted using a gingival index and a plaque index at baseline, one, two, and four weeks. Statistical analysis was done using IBM SPSS Statistics for Windows, version 23 (IBM Corp., Armonk, NY, USA). Intergroup analysis was done using Mann-Whitney test and intra-group analysis was done using Kruskal-Wallis test for all the study parameters. Statistical significance was set at a p-value of less than 0.05. RESULTS: The mean plaque index scores were 2.02 ± 0.12 and 2.29 ± 0.21 in the subgingival scaling and microneedling with olive oil group respectively in baseline. The scores were 1.83 ± 0.29 and 0.57 ± 0.16 in the subgingival scaling and microneedling with olive oil group respectively at the end of four weeks. The results of plaque index scores were statistically significant between the control and the intervened groups at the end of four weeks with a p value of 0.01*. The mean gingival index scores were 2.09 ± 0.16 and 2.37 ± 0.17 in the subgingival scaling and microneedling with olive oil group in the baseline respectively. The scores were 1.88 ± 0.23 and 0.96 ± 0.21 in the subgingival scaling and microneedling with olive oil group respectively at the end of four weeks. The results of gingival index scores were statistically significant between the control and the intervened groups at the end of four weeks with a p value of 0.01*. CONCLUSION: Our research showcased a novel and effective technique, unveiling a significant enhancement in gingival health accompanied by a reduction in both the average gingival index and plaque index.
RESUMO
Vitiligo is considered an autoimmune disease, and its treatment is challenging. We assessed and compared the effect of fractional erbium:yttrium-aluminum-garnet (Er:YAG) laser-assisted delivery of platelet-rich plasma versus microneedling (Mn) with platelet-rich plasma (PRP) in enhancing skin repigmentation in localized stable vitiligo patients. In total, 40 patients with localized stable vitiligo were selected in a random manner into two similar groups (20 each). Group (A) was subjected to fractional Er:YAG laser combined with platelet-rich plasma and Group (B) was subjected to microneedling combined with platelet-rich plasma. The procedure was repeated every 2 weeks for up to 6 months. Each individual was assessed clinically utilizing Vitiligo Area Scoring Index (VASI). Fractional Er:YAG + PRP group achieved better pigmentation100% (excellent 30%, very good 15%, good 30% and satisfactory 25%) which is comparable to Mn + PRP where 80% of cases demonstrate repigmentation (20% very good, 10% good and 50% mild). When comparing the VASI scores for both groups after therapy to the baseline VASI, there was a statistically significant decrease [p = 0.001 for group(A) and 0.003 for group(B)]. Regarding the treatment side effects, there was significantly (p = 0.048) side effects among cases treated with microneedling group(B) (25%) than those fractional Er:Yag laser therapy group(A) (5%). Both forms of therapy demonstrated induction of repigmentation of vitiligo, but fractional Er:YAG laser efficacy is greater when combined with platelet-rich plasma.Clinical trials.gov identifier: NCT05511493.

OBJECTIVES: To investigate the efficacy of Fractional Radiofrequency Microneedling (FRM) in treating corticosteroid-induced facial erythema. METHODS: A retrospective study was conducted involving eight patients diagnosed as corticosteroid-induced facial erythema. Each patient underwent a single session of FRM. Evaluative measures included Clinician's Erythema Assessment (CEA), Patient's Self-Assessment (PSA), assessment of telangiectasia severity, procedure-associated pain (10-point scale), patient satisfaction (3-point scale) and secondary outcomes. RESULTS: The study found a 75% success rate and 100% effectiveness rate in alleviating erythema symptoms. CEA and PSA scores decreased by 67.7% and 78.1%, respectively. No cases of erythema rebound were recorded during the 3-month follow-up period. CONCLUSIONS: FRM demonstrated effectiveness and safety in treating facial erythema, offering promising advancement in dermatologic therapeutics.

INTRODUCTION: Severe acne breakouts often lead to atrophic acne scars, which affect millions of people worldwide and can significantly affect a person's self-confidence and self-image. Given the difficulty in treating atrophic acne scars, this study aims to investigate the efficacy of topical phenytoin in the treatment of atrophic acne scars. METHOD: This split face clinical trial on 25 patients between the ages of 18 and 40 involved the application of microneedling on one side of the face, with three sessions taking place over the course of a month. On the other side, a 1% phenytoin cream was administered three times daily for 1 week following the microneedling procedure. Baseline information was collected for all patients, and follow-up assessments were conducted during the treatment sessions and 2 months after the last session. The assessments included evaluating the number and area of pores and spots, determining scar severity, assessing patient satisfaction, and recording any potential complications. RESULTS: Among patients, 20 individuals (80%) were females, and the average age of the participants was 35.96 ± 9.23. In terms of the fine pore area, despite the fine pore count, both groups showed improvement over time (p: 0.03 vs. 0.06). Also, regarding large pore count and area, and the count and area of spots, both groups showed improvement over time (p: 0.001). However, there were no significant differences between the two groups (p > 0.05). On the other hand, when it comes to acne scar grade and patients' satisfaction, the phenytoin group outperformed the control group in all follow-up sessions and this difference was found to be significant (p: 0.001). It is worth noting that no complications were observed among any of the patients. CONCLUSION: It appears that combining phenytoin cream with microneedling has a more effective therapeutic outcome in enhancing atrophic acne scars, when compared to microneedling alone, and this method can be regarded as a viable alternative in treating these types of scars.

Background Gingival pigmentation (GP), characterized by the presence of melanin in the gingival tissues, is a common aesthetic concern in dental practice. While it poses no inherent health risks, the visible discoloration may cause psychological distress for individuals seeking optimal dental aesthetics. Understanding the efficacy of various methods is essential for refining treatment strategies and enhancing patient satisfaction in the realm of gingival depigmentation (GD). Aim The objective of the study was to compare the effectiveness of scalpel and microneedling (MN) with ascorbic acid in the treatment of GD. Materials and methods Sixteen patients who had a complaint of GP were included in the study, of whom eight were allocated for depigmentation with a scalpel, and the other eight patients were treated with the MN technique with ascorbic acid. Postoperative wound healing scores were evaluated on the first and seventh days, respectively. The intensity of depigmentation was assessed at baseline, in the first month, and at the end of the third month, respectively. Results The mean Dummett-Gupta Oral Pigmentation Index (DOPI) score at baseline was 2.65±0.16 and 2.61±0.17 in the surgical and microneedling groups with ascorbic acid, respectively. The mean DOPI score at the end of the third month was 1.67±0.39 and 0.87±0.17 in the scalpel and MN with ascorbic acid groups, respectively. There was a statistically significant difference between the scalpel and MN with ascorbic acid groups at the end of the first and third months, respectively, where MN with ascorbic acid showed aesthetically pleasing outcomes. Patients treated with the scalpel technique showed incomplete healing and ulceration on the first and seventh days after the procedure when compared to the MN technique with ascorbic acid. The healing index scores were statistically significant in the MN with ascorbic acid group. Conclusion The MN technique with ascorbic acid is a successful technique for treating GD. It showed aesthetically gratifying outcomes when compared to the conventional surgical technique.
