I bought this at the beginning of my skincare journey when hyaluronic acid was all hyped up. I just wanted a big bottle at a cheaper price. I use this product directly on wet skin just after a shower. No, I do not pat dry my skin before using it. I feel that wet skin absorbs this product much better than pat-dried skin. I know that bigger molecular hyaluronic acid should go last after I apply smaller molecular products. That's why when I don't want to put anything else on my body, I use this ampoule. I use it periodically, not after every shower. I feel that it retains moisture in my skin, so it's a good product. However, I plan to buy a single lotion/moisturizer for my body that contains hyaluronic acid, collagen and other beneficial ingredients including ceramide and panthenol because it will save my time.
