U.S., Sept. 2 -- ClinicalTrials.gov registry received information related to the study (NCT07797517) titled 'Microneedling With Glycolic Acid or Trichloroacetic Acid for Atrophic Acne Scars' on Aug. 27.
Brief Summary: Atrophic acne scars are depressed scars that can remain after acne has healed. Microneedling is a procedure that uses very small needles to create controlled micro-injuries in the skin, which may stimulate collagen production and improve scar appearance. Chemical peels, including glycolic acid and trichloroacetic acid, may also improve acne scars.
This study compares three approaches for treating atrophic acne scars: microneedling followed by a 35% glycolic acid peel, microneedling followed by a 15% trichloroacetic acid peel...
