Hyaluronic Acid 3 Serum

Lord it makes my skin feel plumper, firmer and smoother. It's so thick and you only need 3-4 drops for the face and neck &! I'm hooked!!! The price was very good as well. I just know this bottle will last quite a while!

BEST ON THE MARKET!! Starting with packaging - so beautiful and luxurious! The bottle is high quality
- dark amber glass to protect the quality of the product w/glass dropper is so beautiful! My face feels so amazing when I put this product on, I had to buy more immediately for fear of running out! My fine lines disappear and my skin looks & feels great!! I go with no make-up all of the time now because my skin looks so good, I don't feel I need to cover it. Try it, you won't regret it!

Dope Product

This is such a cool product!

I concentrate it in my T zone ??keep the area hydrated so dead skin doesn't clog my pores there.

But what I love it for most is my lips! You need just the leftovers on your fingers from applying to your face. every week or so I combine it with my sugar lip scrub and a mask. Haven't had dry, cracked or chapped lips since!
