Im facing acne problem from menarche, I've visited n number of dermatologist from my college days and had the same accurate tablets with external creams which works for a while and acne comes back right after I stopped using it. I want to know the root cause for my acne and how to treat it completely without too many tablets, is there any test that I can do? The scars get darker because of high melanin production (also my skin reacts if I'm exposed to sun). My diet doesn't include junk food and much oily food and my skin care is minimal, any help is much appreciated!
