Hyaluronic Acid Benefits:
Elasticity
Moisturizing

Hyaluronic Acid, also referred to in skin care as hyaluronate or HA, is a naturally occurring polysaccharide that is found throughout the skin. Hyaluronic acid is glorified for its ability to enhance moisture-retention and skin-hydration. This is due to hyaluronic acid’s ability to hold up to 1000 times its weight in water. For this reason, products with hyaluronic acid (i.e. hyaluronic acid lotion, hyaluronic acid cream, hyaluronic acid liquid care) may serve as effective skin-soothing therapeutics for skin dryness. 1

As we age, our levels of hyaluronic acid and collagen decline, thus making our skin more susceptible to aging signs (i.e., fine lines and wrinkles). Topical application of hyaluronic acid has been shown to help decrease water loss from the skin’s surface as well as draw in moisture from the surrounding environment. By significantly increasing the water content in the stratum corneum, various skin factors, such as barrier function and texture, can be improved. 2 This may also enable hyaluronic acid skin care products to play a role in improving skin-elasticity.  Hyaluronic acid can most commonly be found in moisturizing skincare products such as lotions, creams, and serums. 1
