The presence of Hyaluronic Acid within epidermal tissues guarantees elasticity, softness, brightness and hydration to the skin, shielding it from damages caused by external agents and physical stress. During summertime, such damages are likely to increase as direct UV irradiation brought about by unprotected sun exposure may kick off the process known as photoaging. By inducing the formation of free radicals, UV rays trigger the progressive loss of cutaneous Hyaluronans, weakening the main molecule responsible for binding and retaining water. As such, photoaging results in dehydration, atrophy and loss of elasticity and it is the main factor behind blemishes, wrinkles and even skin cancer.
A skincare routine that includes cosmetics with Hyaluronic Acid before and following exposure to sunlight become a valuable asset to maintain a healthy skin water balance and contrast the oxidative stress caused by the action of free radicals. In fact, not only the hydrophilic nature of HA makes it the workhorse of moisturisers, but it functions as a free radicals’ scavenger as well, promoting an antioxidant action and smoothing the effects of harmful sun irradiation on human keratinocytes.
