I'm mid-20s, and sadly am the bearer of pitted acne scars and the odd breakouts here and there. Came across this study www.ncbi.nlm.nih.gov/pmc/articles/PMC6002315/ last night, and I was wondering, has anyone ever used Differin and seen any improvements with regards to their atrophic scarring?
Also, the most commonly prescribed one (I think) is the 0.1% version. How effective is that comparatively?
