melasma
"I was prescribed this by my dermatologist because I was developing brownish skin on my upper lip during the summer when I have more sun exposure. I have been on the same birth control for 12 years and never had an issue until now. I tried a bleaching cream from Amazon that didn't do much. My insurance (Anthem Blue Cross) is known to be pretty good, but because this is a cosmetic issue it is not covered. I spent about $150 on this tube of TriLuma cream. The cost is horrendous, but I only need a dab at night and after a week of use my issue has been cleared! I use SPF  100 sunscreen on my upper lip and a dot of this cream at night and I am all set. It is worth it for me."
