I have had a brown line and spots appear on one side of my top lip, on the actual lip line. It starts right at the peak with a few spots & changes the shape of my lip and causes assymetry with the other peak. Then a brown line trails off down my lip like lip liner. Is this melasma? If so, how can it be treated since it is actually on the delicate lip area? It looks worse in person & was hard to photograph. Please help!
