Adapalene
"I definitely recommend Adapalene Gel. I have had acne for the past 3-5 years. I am 29.  I never had acne like this before this time period. I was skeptical at first but now I can leave the house without trying to unsuccessfully cover my redness, scarring, and pimples. The scarring is still there but it is faint. There are only 2 small negatives I experienced while taking it ...1. When my face sweats (wearing a hat, being in a hot room, or working out) it just burns badly. 2. When I started it my face felt like it was on fire a lot.  Initially. I switched to every other day when using it. Now I use it before bed w CeraVe  moisturizer. I only use 1 PEA size for my entire face.  Don't over do it.  It'll help you just need to be patient. :)"
