The history of hyaluronic acid in aesthetic medicine goes back several decades. Since then, hyaluronic acid has transformed aesthetic dermatology, evolving from a simple skincare ingredient into one of the most effective anti-ageing tools available today.
Hyaluronic acid, or HA, is a glycosaminoglycan that occurs naturally in the human body, particularly in the skin, connective tissue and eyes. Its main function is to retain water, keeping tissues well lubricated and moist. HA’s potential as an aesthetic product was first recognised in 1960, when researchers discovered its ability to act as a powerful moisturiser and stimulate collagen production.
However, hyaluronic acid was not marketed as an injectable filler until the late 1990s. Before it entered the market, the most common filling products were collagen and silicone, both associated with potentially significant side effects. HA changed the beauty market because of its safety, effectiveness and prolonged duration.
The first hyaluronic acid filler approved by the US Food and Drug Administration (FDA) was Restylane in 2003. Restylane consists of non-animal stabilised hyaluronic acid (NASHA), a biocompatible gel that fills skin wrinkles and folds, increases volume and gives a more youthful appearance. In subsequent years, other hyaluronic acid products, such as Allergan’s Juvederm, entered the market to meet growing demand.
Aesthetic uses of hyaluronic acid include correcting selected wrinkles and restoring facial volume, according to the product’s indications. Lipofilling is a transfer of the person’s own fat, rather than an injection of hyaluronic acid. A doctor must select injection techniques and devices according to safety, indication and product instructions.
Another important development in fillers was the introduction of cross-linked hyaluronic acid fillers. Cross-linking creates chemical bonds between hyaluronic acid molecules, making the filler more resistant to breakdown and allowing longer-lasting effects.
Research into fillers continues to investigate materials and techniques. Standard hyaluronic acid fillers should not be confused with treatments containing stem cells or growth factors: composition, indications and evidence must be checked for each specific product.
The history of hyaluronic acid fillers reflects developments in aesthetic medicine. These products can be used for specific indications following medical assessment of benefits, limitations, duration of results and possible complications.
How hyaluronic acid fillers have evolved
Hyaluronic acid fillers have evolved significantly over the years. Modern formulations differ in concentration, degree of cross-linking, elasticity and ability to integrate into tissues. These characteristics allow doctors to choose different products according to the area being treated and the desired result.
In aesthetic medicine, hyaluronic acid can be used to correct volume loss, improve facial contours, treat certain wrinkles and balance areas such as the lips, cheekbones and facial profile. Product and technique choices should always be tailored following a medical assessment.
The evolution of fillers has therefore enabled a shift from simply ‘filling’ to treatments focused more on facial harmony and natural-looking results.
