you might want to go to your gp again if it’s leading to scarring.. i was prescribed adapalene (and anti-biotics at one point) for mild-moderate acne, so even if you don’t get acutane specifically, they should at least offer you some medication / refer you to a dermatologist.
when it comes to skincare, sometimes less is more. i learned the hard way that more =/= better. right now, i just use a cleanser and moisturiser. you shouldn’t be using exfoliants every day or anything. when i run out i’m gna switch my routine to upcircle, probably.
