Hyaluronic acid is a naturally occurring compound in our bodies that attracts and binds water. It has become a widely used ingredient in a range of skin care products, from serums and moisturizers to eye creams and sunscreens. Using products formulated with hyaluronic acid can improve the look of aging skin by helping to replenish moisture and fill in or plump fine lines. Hyaluronic acid contributes to skin’s dewy smoothness when you’re young. But its production in the body decreases as you get older, resulting in the loss of volume and hydration. That’s why hyaluronic acid has become a popular ingredient in many skin care products, including serums, moisturizers, night creams, sheet masks, sunscreens, and injectable fillers. It can help restore lost volume, replenish moisture, and soften the appearance of wrinkles by filling deflated skin folds.
