A naturally versatile humectant, hyaluronic acid (HA) is used across the health and wellness industry in everything from skin and hair products to supplements that can help bolster joint health.
The ability to retain water is essential to maintaining healthy skin, as well as supporting every other function in the human body, according to Revelox, a Canadian company specialising in skincare products formulated with HA. It explains that HA is a sugar that is found naturally occurring in the human body and a key component in the structural health and hydration of cells and tissue. This is because the levels of HA help to indicate the body's ability to hold onto existing water.
A paper published in the Journal of Dermato-Endocrinology, titled, ‘Hyaluronic acid: A key molecule in skin ageing’, describes the functions of hyaluronic acid as ‘hydration, lubrication of joints, a space-filling capacity, and the framework through which cells migrate’.
The paper goes on to say that ‘the synthesis of HA increases during tissue injury and wound healing and HA regulates several aspects of tissue repair, including activation of inflammatory cells to enhance immune response and the response to injury of fibroblasts and epithelial cells’. In other words, not only does HA help maintain healthy skin, but it plays a major role in the body's healing process and could help to repair skin that is damaged by the process of ageing or injury.
