Hello, I’m an 18M. Last month I had some acne because of my diet, but the acne itself is gone now. The problem is that the post acne redness is still there.

Usually the redness left after my acne takes around 2–3 months to fully fade on its own. I currently don’t have any skincare routine, but I want to know what products or ingredients could help speed up the recovery process.

How effective are products like azelaic acid, retinoids, niacinamide, etc. for post-acne redness? Realistically, can they make it fade 1.5x–2x faster, or is the difference usually small?

I’d appreciate any advice or personal experiences.
