I've got these really stubborn dark circles under my eyes, and they're not going away. Also, my upper lip is super dark, and my lip line is nearly black. I'm wondering if I might have melasma because there's noticeable pigmentation all over my facelike on my nose, around my mouth, eyelids, under my eyes, the sides of my cheeks, and my temples. Then there are these leftover dark spots from past acne, and new ones still popping up with ongoing acne, but I can kind of manage the acne when I stick to the right diet. The pigmentation is what's really bugging me though. I'm trying to avoid any advanced treatments, but I'm open to medication and following a routine. Right now, I just cleanse, tone, use eye cream, serum, both day and night creams, and sunscreen. Yet, it doesn't seem to be helping much, even though I'm consistently applying sunscreen. What would you suggest I do?
