If your texture is caused by dry skin, or the texture of your skin creates sagging, then hyaluronic acid is a must-have in your lineup. Hyaluronic acid (HA) is a natural humectant, which means it retains moisture. 

For HA, that’s 1,000 times its weight in water. So, it’s really hydrating. “It helps smooth the skin surface due to increasing the amount of water in the dead cell layer, which delivers moisture to dry, rough skin surface,” Loretta Ciraldo, M.D., FAAD tells mbg.

Consider this hydrating acid like a tall glass of water for your skin. You can choose to use it in the form of a serum (like one of these mbg-approved picks) or look for hyaluronic acid in your moisturizers and face creams.
