Melasma aka Sun Mustache

Ash

Has anyone ever dealt with Melasma, aka "Sun Mustache"?

So, this summer I have done a ton of fishing out in the boat. Being stupid I never applied any sunscreen throughout the summer and ended up getting severely burned. I now have this horrible and ugly skin darkening in between my nose and upper lip. It looks like a fricken mustache. No foundation, powder or concealer will cover it up. In fact, it actually makes it worse! I've been doing some research and have been looking up products for this awfulness online. My question is, if anyone has dealt with this and had success getting rid of the sun mustache, what steps did you take and what product(s) did you use?
