I would like to talk about this Ampoule first ! , before 2weeks , my skin is dry, but after using this product ,I don't feel dryness anymore , the Ampoule left my skin so hydrated and sooth , the texture not sticky Also, because of the mask, my skin had a redness, but I felt that it was getting better and better after using this product, and it was so good. It's a product always want use if my skin really troubled with redness!.
