With recent celebrity endorsements, it may seem as though hyaluronic acid (HA) is making a new splash in the skincare market. However, in the professional skincare arena, HA has been a tried, true, and favored ingredient for decades. Hyaluronic Acid was originally discovered, isolated, and investigated in the 1930s by German biochemist Karl Meyer and colleague John Palmer. They were working in the department of Ophthalmology at the College of Physicians and Surgeons at Columbia University. Their discovery led to an understanding of HA as an essential part of eye health, but their findings opened to door to the vast understanding of physiological effects of HA throughout the entire human body. There are thousands of published peer reviewed studies and papers (nearly 32,000 in one journal alone) on HA, many concerning skin mechanisms. Hyaluronic acid plays an essential role in cell migration, proliferation, and differentiation. It is imperative for healthy cell function, especially in the dermis and epidermis as 50% of the body’s natural HA is found in the skin. As we age, natural HA production slows and supplementation not only fills the gap left from lack of, but also initiates (or inspires) the body’s HA production. In the proliferation phase of skin cells, hyaluronic acid synthesized mainly by fibroblasts allows a temporary extracellular matrix, the diffusion of nutrients and the elimination of waste products. This represents a reservoir of growth factors. Because of HA’s ability to absorb water, maintain moisture, and limit cellular adhesion, it is essential in skin cell function and in wound healing (especially in controlled procedures, i.e., chemical peels, laser protocols, CIT therapies…) BIO Hydra Infusion: HA + so much more One of the most celebrated skin hydrators, hyaluronic acid can aid the skin in its ability to retain hydration as well as increase suppleness and elasticity, however, it rarely acts alone (effectively). It is one of those ingredients that needs an entourage, a clique, a group, an army of other effective ingredients to elicit a certain biological response in the skin. Lira Clinical’s BIO Hydra Infusion combines hyaluronic acid with silver ear mushroom extract and panthenol to quench thirsty, dehydrated skin and boost hydration retention in every season, especially in the heat of summer.
