There are multitudes of skin care ingredients on the market that sound as innocuous as they are, like honey, shea butter and aloe. Hyaluronic acid, on the other hand, isn’t one of them. Though it sounds suspiciously harsh, hyaluronic acid is basically just a sugar found naturally in the skin that holds water, according to Dr. Corey L. Hartman, founder of Skin Wellness Dermatology in Birmingham, Alabama. “It’s a clear, thick, gel-like substance that our body produces and can be found in high concentrations in the skin, connective tissue and eyes. It helps to retain and attract water and keeps tissues hydrated and lubricated.”

In layman’s terms, it’s a hydrating ingredient that our body already produces — similar to squalene — and it’s a must-have to keep mature skin looking plump, hydrated and dewy. Even better, it plays nicely with almost every other ingredient and skin type, according to Dr. Joshua Zeichner, the director of cosmetic and clinical research at Mount Sinai Hospital’s department of dermatology. “Think of hyaluronic acid like a sponge that grabs onto water and pulls it into the outer skin layers to hydrate and plump. It can be combined with almost all other skin care ingredients without any stability issues. Plus, it can be used across all skin types, even people who are oily or those who are sensitive.”

How to use hyaluronic acid

Most derms, including both Hartman and Zeichner, recommend using hyaluronic acid in serum or moisturizer form due to its inherent hydrating properties. Hyaluronic acid serums and gel moisturizers “work well for all skin types, but especially oily skin since it provides hydration, but no heaviness or pore-clogging.” And the last thing mature skin needs is something else pulling it down.

Still, there’s one trick for application that Zeichner swears by: “My only rule when it comes to hyaluronic acid is to apply it to damp skin or with damp fingers to give it the water it is looking for. If you’re using a straight hyaluronic acid serum, layer a moisturizer on top to lock in hydration.” It’s a must-have ingredient for a dewy, youthful-looking complexion.
