First off let me say I’m extremely impressed with the price! I’ve reviewed several Hyaluronic Acid Serums and this one is by far a steal of a deal! You get an entire 2 oz bottle for only $13.95!!! When I got mine in the mail the first thing I noticed was the perfectly silky texture that I love so much. I’ve tried a few HA products that were actually watery which I’m not fond of. The reason I love this texture so much is because just one drop is enough to cover your entire face an neck because it’s so slick and it doesn’t leave any kind of sticky residue. It comes in a beautiful dark cobalt blue bottle to protect the serum from the light. If it wasn’t in a dark bottle to prevent light from getting to it then it would degrade the potency of the product. After using this serum day and night I noticed a drastic difference in the fine lines around my eyes and the edges of my lips. The beauty of HA serum is that it works right away and you can see the difference immediately which I LOVE! My bottle was mailed to me as a sample so that I could try it for myself and review it. After trying it I’m thrilled with it and will be ordering it again! I really like that it’s pure HA serum, it’s a nice size bottle; it’s made in the USA, and has the perfect texture! If you’re interested in purchasing this product you can find it on sale at Amazon for only $13.95!
