Facial Acne Scarring

AbstractAcne scarring is a common disfiguring complication of acne, and fractional lasers are widely applied in improving it. This study is to compare the efficacy and safety of fractional non-ablative 1927 nm thulium laser (FTL) and fractional ablative 2940 nm Er:YAG laser (FEL) in the treatment of acne scarring. Subjects with moderate or severe atrophic facial acne scarring received 3 sessions of FTL on the left side of face and FEL on the right side of face at an average interval of 4–6 weeks. Major assessments included Goodman&Baron quantitative global scarring grading system (GBS), self-rated improvement and satisfaction score. Twenty-seven subjects completed the study; for FTL side, average GBS decreased from 11.15 ± 5.04 at baseline to 7.07 ± 4.87 with an improvement percent of 36.54%; for FEL side, average GBS decreased from 10.81 ± 4.46 to 7.00 ± 4.07 with an improvement percent of 35.27%. Adverse effects include transient pain, erythema, edema, and increase of acne. No significant difference was found between two lasers. Both FTL and FEL improved atrophic acne scarring and were well-tolerated. Increase of acne during laser treatment may have a negative impact on efficacy. Trial registration number was NCT04813419 and date of registration was 19th, March, 2021, retrospectively registered.

Background: Acne vulgaris is a common condition with a prevalence of over 90% among adolescents and post- acne scarring is a well known sequelae. Different types of scars (ice pick, boxcar, and rolling scars) warrant a customized approach of treatment for each type. We propose a novel treatment of atrophic acne scars using combination of subcision and microneedling. Methods: Ten consecutive patients of skin types III - IV with moderate and severe facial acne scarring received three sequential subcision and microneedling treatments after informed consent over a period of three months with an interval of 4 weeks between each session. Goodman and Baron’s qualitative and quantitative acne scar grading systems along with side by side comparison of pre operative and post operative photographs were used for assessment at the end of three sessions of the combination procedure. Results: Estimation of improvement with Goodman and Baron’s Global qualitative acne scarring system , we found good results in patients with Grades 3 and 4 acne scars. Out of 7 patients with grade 4 scars, 29% showed improvement by 2 grades and 71% showed improvement by 1 grade and all the 3 patients with grade 3 scars showed improvement by 1 grade. Quantitative assessment showed 30% patients had minimal improvement, 50% had moderate improvement and 20% had good improvement in scars. Adverse effects were transient pain, erythema and oedema. Conclusion: Subcision and microneedling are simple and inexpensive office procedures which in combination are well tolerated and are efficacious in treatment of moderate and severe acne scars.

Facial Acne

In the past, the treatment of “ice pick” and pox-type scarring has been a perplexing problem. Successful methods of treatment have included excision, punch excision, and punch replacement. These are usually first-stage procedures, however, and often require secondary treatment. This paper describes a method of treating these types of scars with the CO2 laser which can give excellent results and, in some cases, be an end-stage procedure.
