▻ Skin aging and its mysteries: a complex and fascinating universe yet to be fully unravelled. In such a universe, sun exposure exerts a crucial influence, especially now that, as the sunny season approaches, we are more and more tempted to show a sunbathed look.
In fact, skin is not only subjected to intrinsic ageing, but also to extrinsic processes induced by external factors, among which ultraviolet (UV) irradiation is one of the most dangerous. This depends on UV rays’ ability to penetrate the skin according to their wavelength. In great quantities, UV rays are responsible for erythema and skin burns, but even minor exposure may cause more subtle, long-lasting damages, such as blemishes, wrinkles, or even skin cancer. Such process is know as photoaging.
Experts estimate that approximately 80% of facial premature skin aging should be attributed to unprotected, repeated and extended UV-exposure, which induces simulate a typical wound healing response. UV rays are the main responsible for the formation in skin tissues of free radicals, unstable oxygen molecules that cause oxidative stress, stealing energy from healthy cells and breaking down the collagen. During this process, scientists also observed the progressive disappearance of epidermal Hyaluronic Acid resulting in the loss of the main molecule responsible for binding and retaining water, leading to dehydration, atrophy and loss of elasticity.
Within such a context, Hyaluronic Acid supplementation provides a double protecting function. Firstly, it’s essential in order to restore and maintain an adequate skin moisture and hydration, especially in hotter seasons when our epidermis is more vulnerable and its endogenous HA stashes are running low. In the second instance, researches have shown how Hyaluronans acts as a free radicals’ scavenger, forwarding an antioxidant action and minimising the effects of unhealthy sun irradiation on human keratinocytes.
As such, when summertime approaches, make sure to take care of your skin and prevent photoaging in the correct way. Hyaluronic Acid oral supplementation – such as our SinoHyal FG line – turns out to be extremely an effective natural way for restoring skin health from the inside out: clinical studies confirmed that ingested Hyaluronans gets assimilated by our organism and effectively redirected to the peripheral parts of our body, skin tissues included.
