I've seen a lot of people promoting Mandelic acid and glycolic.. what's the overall best for fading the red marks on your skin? I'm looking in to Salycilic and Hydroquinone too.

Also, might add that I'm on a low 10-20mg dose of accutane.. I've already been on 2 doses to get rid of my acne which cleared my skin up completely.. but unfortunately staying on a low dose is the only way to keep my skin clear.. I also really don't want to have to deal with these ugly red marks! So I'm at a crossroads.. any advice would be much appreciated.

Thanks in advance.
