“I try all sorts of serums, and Dermatica Hyaluronic Acid Hydrating Serum with Vitamin B5 is a very nice one. It does not leave my face feeling sticky or tacky, which is a common occurrence. It absorbs in quickly and leaves a nice, smooth feeling. I haven't noticed a huge improvement in my fine lines, but they didn't get there overnight, either!! Still, I like it!!”
