Hyaluronic acid is a common ingredient found in skin care products. Used mostly as a moisturizer, hyaluronic acid can hold up to 3,000 times its weight in water. As a result, hyaluronic acid serums help deliver powerful hydration to the skin in one step.



Types

Hyaluronic acid serums come in various forms, depending on skin type. Water-based hyaluronic acid serums are designed for normal and combination skin types. Lipid-based serums are designed for dry or more mature skin types.

Function

Both types of hyaluronic acid serums provide intense moisture to the skin. Hyaluronic acid is typically time-released, providing hydration for hours at a time. Most skin care products with hyaluronic acid recommend application of the product twice a day.

Identification

Most products will list hyaluronic acid directly on the label. Sodium PCA is another form of hyaluronic acid that may be on a skin care label.

Benefits

Hyaluronic acid serums keep the skin soft, supple, firm, and moisturized, which help prevent breakouts and signs of aging on the skin.

Expert Insight

Hyaluronic acid is safe for even the most sensitive of skin types, making it a popular ingredient for many skin care products. Because it is also affordable, it can be found in many products at a drug store.
