Review (3/5): Great for tightening your skin if that's what you're looking for.
I've waited for a while to review this item, because after all, skin products need time to see if it actually works. My experience with Derma-nu Hyaluronic Acid is different from others that I have used in the past. I felt the tightness in my face where I used it right away, tightness to the point that it felt that my face is super dry. My face is combination skin. I don't want my face to be extremely dry. I know that one's face has to be moisturized because that's what makes it soft. I didn't see any reduction on the fine lines in my forehead. I did apply my other moisturizer after. I like that it's 72% organic, as it claims; I have a different serum that it's 100% organic and that it brightens my skin without extremely drying.
If the effect you're looking for is skin tightening then this product is for you. But it didn't work for me for fine lines reduction. I didn't see any skin brightening either. Hence the three stars for me.
