What Exactly Makes Hyaluronic Acid So Beneficial to the Skin?

Found in moisturizers, serums, sheet masks, and injectables, hyaluronic acid is a key component of any healthy skin regimen. We asked some industry experts to share what makes the ingredient so beneficial to the skin.

“HA increases collagen synthesis for normal skin function and is critical to the structural integrity of the dermal collagen matrix. However, because hyaluronic’s water-binding molecule has such a short life span—we’re talking one to three days—it requires constant replenishing topically and through foods like leafy greens, almonds, bone broth, avocados, and peppers.”—Shannon Esau, CEO & national educator, Rhonda Allison Cosmeceuticals

“HA provides numerous benefits for the skin and body, but because it can retain moisture so well, it can help the skin stay hydrated and protected. With this, the skin’s barrier function will be more resilient, and the skin will look plumper, so lines and wrinkles will appear softer.”—Ashley Stowers, national educator & account executive, CelleCle Skincare

"Because of its amazing hydrating benefits, it can reduce wrinkles, redness, and dermatitis.”—Deb Uhrberg, president, Scandic Beauty

“The benefits of HA in cosmetic products depend on its molecular weight. High molecular weight HA, with bigger molecules, will remain on the skin’s surface. It will form a hydrated film due to its important hygroscopic properties, which means it captures and traps moisture. This film will help compensate for any potential water loss. Finally, this nonocclusive film will also have tightening properties and protect against some external aggression. Low molecular weight HA, with smaller molecules, can penetrate deeper in the epidermis, where it will bring interesting results. It accelerates cell renewal, stimulates the synthesis of collagen, which makes it interesting in anti-aging products, as it can contribute to skin repair and the reduction of wrinkles.”—Laure Bouscharain, head of research & development, Biologique Recherche
