I purchased the Divas Never Age Hyaluronic Acid Serum in hopes of improving my skin in both texture and appearance - and it works wonders! Like it states in the directions, you are supposed to apply this serum to your entire face, followed by a moisturizer. When I applied this serum to my face for the first time, I felt my skin tightening (in a good way) and it had a very firm feeling after the application process. I continued to use this serum once per day every time I got out of the shower and I feel that it just adds an extra step in my daily routine towards healthier skin. Also, this product does not make me break out in any way (as I have sensitive skin), hooray! I would recommend this product to anyone looking for tightness and firmness in their facial features, similar to the "youth" effects that several spa facial masks provide.
