Hello, I did 2 chemical peels for my acne. It cleared a lot of my acne, but I still have scars and pigmentation. I have heard that microneedling could help with the pigmentation. First question: Would you suggest this treatment (microneedling) or is there a better treatment for banishing scars and pigmentation? Second question: how long should I wait before doing microneedling after a chemical peel? Thank you!
