Totally agree with you on Tri-luma cream.
I had recently used a sample provided by a dermatologist who did not say anything about testing it first on small spot - his staff only said to use it once a day at night and that’s exactly what I did. After the 3rd night, I felt an extreme burning sensation, I asked his office again what I should do. They said to use it now once every 2 days and I used it another 2 times before realizing that it had permanently burned my face and caused much worse pigmentation than before and with lots of wrinkles too!!
Few days ago I found a website with skin lightening cream reviews. I wished I had checked this website before trying Tri-Luma.
There's also lots of positive Reviews on Meladerm .
Hope it helps melasma suferers a bit.
