This helps to reduce the appearance of fine lines, as well as brighten and even skin tone. The lightweight silky texture creates a perfect make-up canvas.

Review: Your Skin's New Best Friend - Very happy with this product. It really sinks right in when applied, and when used in conjunction with a moisturizer, the results are excellent. Definitely a bargain at this price, too.
Review: Does great and will probably buy again. - Pros: I liked that it does moisturize my face but only slightly better than the Vichy Mineral No. 89 that I normally use. Heard this does better and it does do slightly better for a few dollars less which is great. It dries SUPER quick on the face, once you apply it be quick with spreading it in because my skin absorbed it within a matter of seconds. Absolutely no smell came from this, Idk what people are talking about when they say it has a bad odor. They must've gotten a bad batch or something because this is no different smell than any other non-perfumed product. Cons: It being absorbed TO quickly is a slight downfall on its own but that's more of an inconvenience than anything truly negative about it. Also one pump isn't enough to cover my cheeks, nose, and forehead in one go. I have to do a small pump to do my forehead and temples. It is 30ml so it is on the smaller side versus the 50ml I get in the Vichy Mineral 89 hyaluronic bottle but it is less expensive so I guess I could buy 2 of these and get a total of 60ml versus same price for Vichy's 50ml bottle. Overall I'm happy with it, I'll continue to use it. I've yet to use it and see how it reacts with my La Roche-Posay Effaclar Adapalene Gel. The Vichy and Effaclar combo makes my face feel extremely stiff so I'll comment back after the interaction with the Polyglutamic acid.
