Hello, I have a slight yellowish discoloration around my lips for years. It's <1 inch in every direction around the lips (slightly worse above). No clear demarcation. Can't recall when it started.
I cover it with tons of makeup until it wares off. It's a real confidence killer! I'm mid eastern, light/medium skin tone, smoke 3-7 cigs/day(related?), & had lip filler done 1 y.a. but this was present before that.
What could cause this? Are there any procedures/products that treat it? Please help!
