Which acid is stronger?
Which acid is more potent, glycolic acid or salicylic acid? Which acid would help fade permanent makeup better?

Salicylic is much stronger.

Glycolic is promoted because of some active patents.

Dr. Pickart, is glycolic acid not as strong as lactic acid? Just wondering why you chose to formulate your exfoliant with lactic acid instead of glycolic. What are your thoughts on malic and mandelic acid? Thank you
