Hyaluronic Acid has become a popular ingredient in anti-aging skin care products due to its ability to bind moisture to the skin. Before we can comprehend the value of hyaluronic acid as it relates to the skin, we must first understand the structure of the skin.
The skin is comprised of two layers, the epidermis, the outermost and thinnest layer of skin and the dermis, the inner layer of skin. While the epidermis creates the visual appearance of the skin, the dermis layer provides nourishment to the epidermis through vital blood vessels and capillaries. The dermis layer also houses collagen and elastin, proteins that give the skin its form, strength and elasticity.
Hyaluronic acid is a glycosaminoglycan, a type of carbohydrate that serves as a joint lubricant in the body and is present in connective tissues, cartilage and tendons. The dermis layer of the skin is made mostly of water and contains about 50% of the hyaluronic acid found in the body. Through the aging process, the body’s production of hyaluronic acid decreases therefore the dermis layer of skin becomes dehydrated, limiting the production of collagen and elastin in the skin. This loss of moisture has a negative impact on the skin which leads to loss of volume or hollowing of the face, dull texture and tone and ultimately fine lines that lead to wrinkles in the skin.
Hyaluronic acid is a beneficial ingredient in skin care products because it can hold 500 to 1000 times its weight it water. By increasing the amount of moisture retained in the dermal layer of the skin, hyaluronic acid is able to strengthen the outer layer and promote healthy younger looking skin. Additionally, hyaluronic acid provides protection against free-radical damage that can cause inflammation in the skin.
When looking for skin care products that contain hyaluronic acid check the product label for presence of hyaluronic acid or sodium hyaluronate. Sodium hyaluronate has a smaller molecular size than hyaluronic acid, making it easier to penetrate through the skin. Both ingredients aid in the skin’s ability to retain moisture which can temporarily “plumping” fine lines however, results can vary based on the product and specifically where these ingredients fall in the ingredient deck.
Although topical application of skin care products that contain hyaluronic acid can aid in the skin’s ability to retain moisture, the results will not have the same impact as seen in cosmetic injection from a board certified cosmetic physician.
