I would say time, AHA, some type of chemical peel etc. But im no expert.
How did you end up clearing your face up?
I looked into peels but there's so many different types, I wouldn't know which one is right!!
I had moderate/severe acne on and off for about 4 years. Been on and off anti biotics, but the last course I was on (which I finished in Jan this year) just seemed to make it go for good. But I don't really believe it was all down to that, I think acne will go when it wants!
But I use honey on my face, add a little sugar if it needs a scrub! Natural products. They seem to have helped with it too
