Smile line hyperpigmentation
I’ve dealt with hyperpigmentation before, but nothing like this dark smile line. It showed up out of nowhere one day and has been extremely stubborn ever since. I’ve tried all the usual treatments (tretinoin, azelaic acid, hydroquinone, etc.) and nothing fully clears it. Sometimes it gets red and irritated, then the dark pigment comes right back.
Has anyone dealt with something like this? What is the cause of this dark smile-line and what helped? It’s really affecting my confidence.
What products can treat this?
