Those aren't depressions, it's just PIH. You need to invest in a high PPD sunscreen and use it religiously. Also use tretinoin or tazarotene to tolerance. Do not let the sun get on your face. Mild acids to tolerance might speed up resolution. I think most of us would give up a limb to have skin like yours.

This is not a acne scar, it's hyperpigmentation, specifically PIH in ethnic patients from inflammation. Use a retin-a/tretinorin/differin nightly with a skin whitening cream with ingredients like licorice konjac and or arbutin on say Amazon. This is a slow process to work on. IF this does not work you need a vascular laser from a cosmetic dermatologist or med spa.

We have a whole guide of at home treatments at the top of the hyperpigmentation sub, very first post.
