This is a very light and absorb into skin in a flash. It provides enough hydration for a regular routine, but if you are using acids or retinols, you will probably need another layer of hydration serum.
So far, after two weeks of using this I don’t see much improvement on my face. However, aquatide is fairly new to skin care world, and ingredients takes times to have effects on the skin. I will repurchase this serum again since the scientific research is looking very promising.
