Hyaluronic acid is a naturally occurring molecule found in the human body, primarily in connective tissue, skin, and eyes. It is the main component that gives the skin a plump, youthful, and hydrated look. As an ingredient, it is used as a humectant, which means it draws and retains moisture on the surface of the skin. Hyaluronic acid is a clear, viscous liquid that is typically added to skincare formulations in small amounts. It is often combined with other hydrating ingredients in skincare products, such as glycerin and ceramides, to provide an external boost of hydration to the skin. The chemical formula of Hyaluronic acid is (C14H21NO11)n.

What is HYALURONIC ACID used for?

Hyaluronic acid has a variety of uses in the beauty and skincare industry. As a humectant, it is commonly used in moisturizing products such as serums, creams, and lotions, to help hydrate the skin and reduce the appearance of fine lines and wrinkles. Hyaluronic acid is also used in dermal fillers to add plumpness and volume to the skin, and in some cosmetic procedures to help improve the appearance of certain skin imperfections like scars. In addition, hyaluronic acid is used in some wound healing products due to its ability to promote tissue regeneration and reduce inflammation.


Hyaluronic acid can be made through bacterial fermentation or extracted from plant sources such as wheat or soybeans. In bacterial fermentation, bacteria are grown in a culture medium that contains nutrients, and the hyaluronic acid is then extracted and purified from the resulting culture.

Safety profile

Hyaluronic Acid has been recognized as safe by multiple regulatory agencies around the world. It is non toxic and has a low molecular weight - eliminating the possibility of it penetrating the surface of the skin. Since it is biocompatible and biodegradable, the body can break it down and eliminate it through natural metabolic processes. However, a patch test is recommended.
