Hyaluronic acid. or hyaluronan, is a component of connective tissue in the body. Hyaluronan is needed to cushion and lubricate joints, eyes, skin and heart valves.
Hyaluronan is also a major component of skin and is involved in tissue repair. Declining skin levels of hyaluronic acid are associated with dryness, reduced flexibility, and skin wrinkles. The presence of hyaluronic acid in epithelial tissue has been shown to promote skin hydration. Hyaluronic acid also drives collagen synthesis and normal skin function. These benefits make hyaluronic acid very effective topical method for skin hydration.
For this reason, hyaluronan has now become a common ingredient in skin-care products. For example, in 2003, the FDA approved hyaluronan injections for filling soft tissue defects such as facial wrinkles. Restylane is a common trade name for the product. Hyaluronan injections temporarily smooth wrinkles by adding volume under the skin, with effects typically lasting for six months.
Juvederm is a bacterial hyaluronic acid injectable filler, similar to Restylane, but differing slightly in terms of effect and longevity. It is used for lip augmentation, reduction of folds and wrinkles and removal of scars. The effects of Juvederm treatments are also temporary, and costs are similar to those of Restylane.
Hyaluronan is available topically, as well as through supplements. As with any other supplement or treatment, it is wise to seek your doctor's advise prior to engaging in any ongoing course of treatment.
