I use hyaluronic acid products on a regular basis and I'm very pleased with Divas Never Age. Yes, it does provide me with a moisturizing boost and tightening feel on my face and chest. I also use Argan oil as a skin and hair moisturizer and this serum contains Argan oil. It also contains other ingredients that make my skin feel soft, healthy, and supple. They are aloe Vera, Vitamin E, green tea, pomegrante, and Moringa Oleifera. The Moringa Oleifera plant is rich in antioxidants. I use the serum in the morning and at night. I follow with my moisturizer. This particular serum is not tested on animals. I received this serum for free in exchange for an honest and unbiased review.
