Post acne scarring is a common complication of acne. Cosmetic appearance of the post acne facial scarring can be improved by various methods. Among the procedural methods microneedling (1) is a novel and a promising option. It is a minimally invasive day care procedure for the management of atrophic acne scars. Topical tazarotene 0.1% gel is an effective medical method in the management of acne vulgaris and macular acne scars (2, 3). Based on its mechanism of action and role in collagen synthesis, topical tazarotene is a logical choice to investigate for the management of atrophic post acne scars. This is a pilot study comparing microneedling and topical tazarotene for the treatment of atrophic post acne scarring in regard to extent and rapidity of improvement, patient satisfaction and any adverse events if any.
Thirty six subjects with grade 2 to grade 4 atrophic post acne scars, classified on the basis of Goodman's Qualitative classification (4) criteria will be recruited. Goodman's qualitative and quantitative acne scarring grading system scoring will be performed for the assessment of severity of acne scarring at baseline. The face of each patient will be randomized for monthly microneedling on one side and topical tazarotene 0.1 % gel once a day local application on opposite side, using computer generated random number table. Follow ups will be done at every month until treatment completion (3 months) and 3 months after the last treatment session. Goodman's qualitative and quantitative acne scarring grading system scoring will be performed at 3rd and 6th month follow up visits. An improvement by two grades will be considered as excellent, one grade will be rated as good and no up gradation will be labelled as poor response. Patients will be also assessed by a blinded observer for clinical improvement and scored on a scale of 0 (no improvement) to 10 (maximum) at 3rd and 6th month follow up visits with the help of serial photographs taken under consistent background, position and lighting. All patients will be instructed to assess themselves using Patients' Global Assessment Score 0 (no response) to 10 (maximum) at 3rd and 6th month follow up visits.
The investigators hope the outcome of the present study may propose a newer medical modality for acne scarring, i.e topical tazarotene 0.1% gel, which can be used at home, obviating the need for physician dependant microneedling procedure.

|Masking Description:||An independant senior dermatologist who is blinded regarding the modality used for atrophic acne scarring in each half of the face, will be assessing the outcome scores.|
|Official Title:||Microneedling Versus Topical Tazarotene 0.1% Gel for the Treatment of Atrophic Post Acne Scarring - a Randomized Controlled Study|
|Actual Study Start Date :||June 2, 2017|
|Actual Primary Completion Date :||February 28, 2018|
|Actual Study Completion Date :||March 29, 2018|
Experimental: Tazarotene gel arm
The treatment protocol in this arm will consist of night time application of Tazarotene 0.1% gel during the entire study period. (3 months)
Drug: tazarotene gel 0.1%
Patients will be instructed to apply 0.1% tazarotene gel as a thin film over the affected area once daily in the evening.
Active Comparator: Microneedling arm
The treatment protocol in this arm will consist of four sessions of microneedling at monthly intervals. (0, 1, 2, 3 months)
Microneedling is a method of percutaneous collagen induction
- Acne scar severity grade at final visit [ Time Frame: 6 months ]Change in acne scar severity grade from baseline and at 6 months
- Acne scar severity grade at final visit at 3 months [ Time Frame: 3 months ]Change in acne scar severity grade from baseline and at 3 months
- Patient satisfaction [ Time Frame: 6 months ]Patient satisfaction using Patient's global assessment score done at 6 months
- Adverse events [ Time Frame: 6 months ]Adverse events noted in both arms during the study period of 6 months
