I heard its not good to use benzyl peroxide on scars so I would say to ditch it and stick with the AHA because that fades scars. And dont quit automatically with the benzyl peroxide, keep lessening the amount as the days go by until you finally stop completely. Also, I recommemd tamanu oil, you can see the results I had with the oil on my forum. Ill link it here if youre interested, or you can check on my profile.

So my recommendation: use tamanu oil 4 times a week, and the AHA 3 times a week.
