Hyaluronic acid is a naturally-occurring substance found in the human body. It’s present in large concentrations in the skin, where it helps keep the complexion hydrated and plump. In fact, hyaluronic acid is responsible for up to 30% of the skin’s natural moisture-binding ability.

Hyaluronic acid, a humectant, draws moisture in from the environment through the epidermis (the top layer of skin), deeply penetrating it with beneficial moisture to provide lasting hydration. A humectant is a substance that has the ability to attract and retain moisture almost like a sponge.

It’s this moisture-binding quality that makes hyaluronic acid such an effective ingredient in skin care products. When applied topically, it can help to plump and hydrate the skin, reducing the appearance of fine lines.

As we age, our bodies produce less and less hyaluronic acid, which can lead to dryness, fine lines, and wrinkles. But fear not — topical hyaluronic acid products can help to replenish the skin’s stores of this vital ingredient, boosting hydration levels and giving the complexion a youthful appearance.
