How Long: Azelaic acid

Honestly it took about eight months for my hyperpigmentation to go away but it was really dark in the beginning. it also reduced acne and Milia, I plan to keep using as azelaic acid forever.

I broke out terribly last April & I’ve been using azelaic acid as my main treatment for PIH. It has been a full month now & so far the red marks are still present, but it is significantly lighter!
