Hyaluronic acid occurs naturally in the human body and is recognized for its role in skincare and medical treatments. It boosts the ability of skin to retain moisture, making it a key ingredient in many cosmetic and skincare products.
Knowledge of hyaluronic acid dates back to the 1930s when Karl Meyer and John Palmer first isolated it from bovine eyes. The men discovered that this substance, composed of sugar molecules, had an extraordinary capacity to bind to water, making it a groundbreaking discovery in biochemistry. Its ability to hold up to 1,000 times its weight in water makes it ideal for cosmetics and moisturizing products, including lotions, serums, and other skincare products.
In the human body, hyaluronic acid is found in the highest concentrations in the skin, connective tissues, and eyes. Its primary function is to retain water, which helps keep tissues well-lubricated and moist. Unfortunately, the body's ability to create it decreases with age, resulting in dry skin and wrinkles.
Beyond skincare, hyaluronic acid is used in certain eye surgeries, including cataract removal, corneal transplantation, retinal detachment repair, and natural fluids replacements. Additionally, it's common in injectable fillers used in cosmetic surgery, often to reduce wrinkles or add volume in some regions of the face.
Hyaluronic Acid Day was created by L'Oréal's brand La Roche Posay in 2022 to raise awareness of its importance in healthy skin care and to promote products containing it.
