Product review (4 stars): Awesome product
I have melesma my skin is very sun sensitive and prone to tanning.
When I used this product in 2-3 days my skin looked brighter the dark patches on my face faded and my skin looks much better.
This is the first product which has given me instant results and I love it.
It works best in the shower for me .As it gets activated by water I feel the heat longer when I use it  in the shower.
