Is hyaluronic acid anti-aging?

Anti-Aging About 50% of the body's total hyaluronic acid is present in the skin. Changes in this amount, possibly due to UV exposure, can cause wrinkles to form. Hyaluronic acid can significantly decrease the depth of wrinkles and improve skin firmness and elasticity. Skin aging is also associated with loss of skin moisture.

The key molecule involved in skin moisture is hyaluronan or hyaluronic acid (HA), a glycosaminoglycan (GAG) with a unique ability to bind and retain water molecules, 6 HA belongs to extracellular matrix (ECM) molecules. Over the past few decades, skin components have been well characterized. Initially, most studies focused on the cells that make up the layers of the skin, such as the epidermis, dermis, and underlying subcutis. Recently, it has been seen that ECM molecules found between cells, in addition to providing a constructive framework, exert important effects on cellular function.

These ECM molecules, although they appear amorphous by light microscopy, form a highly organized structure, composed mainly of GAGs, proteoglycans, growth factors and structural proteins such as collagens. However, the predominant component of skin ECM is HA. Hyaluronic acid has become a skincare treatment. While there is little evidence that it works as an anti-aging cosmetic product, you can inject it into your face, a treatment called dermal filler, to decrease wrinkles and increase fullness.

As we age, the production of key substances in the skin decreases, including hyaluronic acid (along with collagen and elastin). As a result, our skin loses volume, hydration and volume. Hyaluronic acid is an effective supplement for skin health. Hyaluronic acid is also injected into the skin to improve skin firmness and for rejuvenation purposes.
