Fantastic product for proper hydration. I apply it only in the morning instead of creme and i'm absolutely happy with the result. Indeed there is no need for any creme or further hydrationg products. It's a two-phased product which you need to chake well before use. Oily and watery phases mix and then you apply it on your face. I use it quite extensively so apply a lot of product but i'm sure you can be good with 3-4 drops. Highly recomended especially for winter season. Doesn't leave any oily feeling on the skin, ideal as a foundation base.
