Melasma
"Some people have commented that their skin actually has gotten darker a few days after beginning to apply Tri-Luma. The same happened to me, but I realized that my problem was that after I applied Tri-Luma before bed time, I would read for about one hour with a light directly on my face. The chemicals in the cream were reacting to the light. I stopped the treatment for a few days. When again I started applying Tri-Luma, I immediately turned off the lights and went to sleep. That worked! After two months I now have about 90% clearer skin (I am olive skinned)."
