I have used several brands of hyaluronic acid serum and found most to be quite nice as they do a wonderful job of providing hydration to your skin as well as tighten up loose saggy skin around my eyes and mouth, which is wonderful in my opinion. Plus I like that it can go under your moisturizer and makeup products, and your makeup doesn't have that caked on look. I like the Amara Organics Hyaluronic Acid Serum, and to be one honest, i do quite like it best. The part that I like the best about it, is it does not have a perfumed or fragrant smell, honestly, I it really doesn't have a smell, it just smells fresh! I as well love the way my skin looks when I am using this product!
