Reviews about Bi-Phase "Hyaluron"

I am disappointed. I always use either luxury or professional skincare products, and in addition to the standard set of serums, creams, and masks, I occasionally add various boosters to my routine, such as ampoules. However, these ampoules did nothing. I used a package of 10 ampoules hoping for some extra hydration or at least some visible result, but I got nothing. Despite having mature facial skin and taking good care of it, which makes it look very good, I understand that it is difficult to amaze such skin with something, but there are still masks and other ampoules that provide visible results after use. But here, there was nothing.
