I recieved the Bioderma Hydrabio Mask as a gift from a friend and I honestly think she, together with this mask is heavenly sent. I suffer from very sentitive skin and hyperpigmentation and im in awe at the way my skin is reacting so well to the product. In just a matter of 2 weeks, I can see a huge difference in my problem areas, its just such a pity I did not take a before and after picture. I would definately recommend to everyone. Im looking forward to using the whole range.
