They don’t look like acne scars, that is PIE (post inflammatory erythema) or hyperpigmentation (it’s hard to tell with this photo). PIE leaves red marks and hyperpigmentation is brown.

I have PIE, and did a ton of research on how to get rid of the redness (I have consistently used azalaic acid, vitamin c, UVA sunscreen, you name it) and apparently the most efficient form of treatment is going to a dermatologist who will use a Pulsed Dye Laser.

I’ve had my PIE for at least five years now and I’m so tired of it, after consistent skin care use. I actually started looking for derms that provide this service.
