HA
Hyaluronic acid (HA) is a naturally occurring polysaccharide that gives structure to tissues and contributes to the optimal functioning of a number of biological systems in the human
body . Because of its intrinsic biocompatibility, biodegradability, and diverse biological functions, HA is widely used in medical devices and pharmaceutical applications, for example eye
drops, viscoelastic devices, and topical formulations. HA also adds new and improved attributes to existing products, while also offering numerous opportunities when developing new ones.
HA for Skin Care Applications
Dermatology is a unique medical specialty dealing with the skin and its diseases. It includes both medical and clinical aspects in the widest sense and addresses issues of the skin, scalp, hair, and nails.
Hyaluronic acid (HA) has distinguished itself in the cosmetic industry due to its incomparable moisturizing properties. Indeed, HA is one of the most hygroscopic molecules found in nature, a property which confers its ability to attract and retain moisture from its immediate environment & later, the documented ability of HA to scavenge reactive oxygen species (free radicals) in vitro earned this naturally occurring macromolecule, the status of being one of the most preferred anti-aging agents for cosmetic products.
As a major component of the skin, hyaluronic acid supports epidermal barrier function and is considered to be the most active guardian of the extracellular matrix homeostasis.
