Review (5/5): Does what it says, but do you need it?
This is a very light moisturizer that absorbs quickly. It is said to be used for layering. So I assume you are meant to add additional moisturizing products if necessary, including moisturizing makeup. As a base layer this would then be underneath, for example, a moisturizing foundation.
I have a much lighter routine so this is superfluous to me. That is, I would go straight to a light, but heavier than this facial moisturizer. But if you need a light moisturizing base layer this is great.
