After reading all these comments about Dermmatch, i have decided to add my 2 cents.
I have been using Dermmatch for two months now and its not what I expected. According to the product, you can swim or play sport with it. Well, guess what? Took a swim today and decided to test out the product. After few lap in the pool, the color disappeared from my head. Also I have tested the product playing basketball. When I started to sweat, I am getting few streaks running down my forehead. Pretty embrassing I would say. Not sure what I do wrong but I thought this product shouldn't do that. I am going to test courve and maybe nanogen after I used up all Dermmatch.
