melasma
"I was told by two plastic surgeons the only thing that would remove my dark spots was laser. Several treatments at that and at a cost of $1500-$3000. I will admit may spots were very dark and covered most of my face. I was at my dermatologist for an unrelated problem and asked about Tri-Luma, which I had seen an advertisement for. He prescribed it for me and I cannot say how happy I am with the results. It  is an expensive medicine (not anywhere close to laser) but it works. Also check around on prices.  My husband noticed a difference within the first week and my family is amazed how light my spots are. I have been on it for about 6 months. I go off for awhile and then start back . Use sunscreen."
