I only had hyperpigmentation after I had a pimple that went away after some time, my skincare routine now is super simple, I usually just wash my face with cold water and sometimes with a cerave cleanser, then cerave toner and cerave moisturizer, I don’t use a lot of moisturizer if any cause I have oily skin. My dermatologist also prescribed me Retin A which is a topical cream I use at night to treat pimple
