ABSTRACT

Background: Severe post-acne scarring has been implicated as a cause of considerable psychological distress, mainly among adolescents. Subcision and microneedling are cutting-edge treatment options available nowadays. Aim: In this study, we aimed to compare the efficacy of microneedling with platelet-rich plasma (PRP) against subcision with PRP in treating atrophic post-acne scars in a split-face study design. Materials and Methods: Fifty patients with atrophic post-acne facial scars were included in this prospective interventional study. Group A included the left side of the face managed by microneedling with PRP and group B included the right side of the face that was subjected to subcision with PRP. Results were assessed based on Goodman and Baron qualitative and quantitative grading. Results: In our study, at the end of the treatment, on the left side, 5 (10%) had 1 grade of improvement showing good response, 35 (70%) had 2 grades of improvement showing very good response, and 10 (20%) had 3 grades of improvement showing excellent response. On the right side, 1 (2%) patient had no improvement in acne grade showing poor response, 9 (18%) had 1 grade of improvement showing good response, 25 (50%) had 2 grades of improvement showing very good response, whereas 15 (30%) had 3 grades of improvement showing excellent response. Conclusion: Till date, apart from ours no other study has compared the two modalities head-to-head with adjuvant PRP in both groups. Although both modalities showed statistically significant results individually, there was no significant difference in qualitative improvement of acne scars between the two groups.

ABSTRACT

Xanthelasma palpebrarum (XP) is a benign cosmetic condition. Although the role of CO2 laser is well described, there are only a few studies on Erbium: YAG in XP. Similarly, trichloroacetic acid (TCA) is commonly used in XP. However, there are only a few studies comparing these modalities in the treatment of XP. Aim: To evaluate the effectiveness and safety of Erbium: YAG laser and 50% TCA in the treatment of XP with the role of dermoscope in the evaluation of lesions. Materials and Methods: A total of 20 subjects were randomly allocated into two groups: group A (TCA) and group B (laser). All patients were subcategorized into three grades viz. I (mild), II (moderate), and III (severe) using a self-devised scoring system. Results: About 25% and 70% of patients achieved complete clearance in groups A and B, respectively (P = 0.017). The rate of recurrence was 40% and 15% in groups A and B. Dyspigmentation and erythema were the most common side effects. Pretreatment dermoscopic evaluation of the lesion showed a network of brown streaks on a background of a yellowish structureless area and was used to assess the area and margins of the lesion where the adipose tissue was found during the procedure and serial assessment of the lesion.

ABSTRACT

Background: Acne scarring not only affects the aesthetic appearance of an individual but also has a detrimental effect on mental health and social life. Various treatment modalities are available for acne scars. Aim: In this study, fractional erbium-doped yttrium-aluminum-garnet (Er:YAG) laser resurfacing was compared with 20% trichloroacetic acid (TCA) peeling in terms of efficacy and safety. Materials and Methods: This prospective comparative study included 50 subjects of acne scar who were randomly divided into Groups A and B, 25 patients in each group. Group A was treated with 4 sessions of fractional Er:YAG laser and Group B with 4 session of 20% TCA application as chemical peeling, repeated every 21 days over a period of 3 months. The patients were evaluated for improvement at each visit using Goodman and Baron's qualitative and quantitative acne scar grading. Results: Statistically significant improvement in Goodman and Barron's qualitative acne scar grades was observed in both groups. At the end of therapy, that is, after 12 weeks of therapy, the mean percentage reduction in Goodman and Baron's quantitative acne scar scores was 21.69% ± 16% in Group A and 20.97% ± 8.70% in Group B. In regards of complications, both procedures were well tolerated. Conclusion: We concluded that fractional Er:YAG laser resurfacing and 20% TCA peel application in the treatment of atrophic acne scar are equally efficacious. Both procedures are safe and well tolerated by the patients.
