Revolutionizing Skin Care: The Impact of Hyaluronic Acid Dermal Fillers on Photoaging Skin

Advertisment

In the evolving field of dermatology and cosmetic research, the use of dermal fillers has gained significant traction. A recent study supported by the University of Michigan Department of Dermatology Cosmetic Research Fund and a Career Development Award from the Dermatology Foundation has reported the beneficial impact of cross-linked hyaluronic acid dermal fillers on photoaging skin.

What is Hyaluronic Acid and its role in Dermatology?

Hyaluronic Acid (HA) is a substance naturally found in the human body and is commonly used in cosmetic dermatology and plastic surgery as a filler to produce more volume and restore fullness. It helps the skin retain moisture, plump up the cells, and smooth existing lines. Plastic surgeons use hyaluronic acid injections to improve the appearance of aging skin. It is generally safe for most people who have had previous cosmetic procedures but may cause allergic reactions and side effects if used in excess.

How do Hyaluronic Acid Dermal Fillers work?

Hyaluronic Acid Dermal Fillers are injectable gels used to add volume to the skin, often in cosmetic or aesthetic procedures. The filler consists of crosslinked Hyaluronic Acid, a substance naturally found in the human body. These fillers offer an effective solution for wrinkle treatment and can restore volume in soft tissues, reshape facial contours, and enhance particular features. The concentration and degree of crosslinking in HA fillers influence their volume-enhancing effect and durability. Several HA fillers have the approval of the Food and Drug Administration (FDA).

The Impact of Hyaluronic Acid Dermal Fillers on Photoaging Skin

Chronic exposure to UV light leads to premature skin aging, including wrinkles and sagging. Recent studies have shown that cross-linked hyaluronic acid dermal fillers can reverse these effects by stimulating the production of new type I collagen in the dermis. Enzymes like proteases and hyaluronidase are also proving to be effective in skincare products.

The study found that these fillers can reverse the dermal changes associated with photoaging by stimulating the production of new type I collagen in the dermis. They provide short-term improvement through space-filling and collagen stimulation, as well as long-term improvement by promoting the accumulation of more collagen over time. Interestingly, a single injection of the filler can rapidly and long-lastingly improve skin by stimulating collagen deposition, reducing the need for re-treatment.

Safety Profile of Hyaluronic Acid Dermal Fillers

A retrospective analysis was conducted in Brazil to assess the long-term safety of a hybrid hyaluronic acid and calcium hydroxyapatite filler, HA CaHA L. The study included 403 participants, with 243 participants having greater than or equal to 12 months of exposure to the filler. Adverse events occurred infrequently and were predominantly mild in severity, with no treatment-emergent serious adverse events reported. The data from this noninterventional retrospective study support the favorable longer-term 12-month safety profile of HA CaHA L, indicating that it has a comparable safety profile to other dermal fillers.

However, certain risks and potential side effects must be considered before use. It is advised to consult with a trained professional for safety when using HA fillers.
