The negative effects of the sun on skin aging are well known. The damage caused by blue light on skin cells is ignored by the majority of people. With the explosion of smartphones, tablets, screens…, we are exposed to them for a large part of the day. A recent study estimates that an adult spends an average of 5 hours a day in front of a screen.
Blue light has a short wavelength that is highly concentrated and produces a lot of energy. The wavelengths emitted by blue light can penetrate the deeper layers of the skin even further than UV rays. As a result, they cause oxidative stress in skin cells .
If the effects are not visible immediately, they appear gradually as the exposures progress. Over time, exposure to this blue light promotes skin problems . Result: the complexion becomes duller and less even.
It could also be that this light is involved in other pigmentation disorders.
Recent studies report that blue light makes it possible to pigment the skin of patients from one hour of exposure, and in a dose-dependent manner, but with less damage to the skin. In small doses, it would offer prospects for dermatological treatment in hypopigmentation pathologies such as vitiligo.

However, at high doses, the harmful effects of blue light could lead to premature photo-aging. The specific development of protection at the narrower portion of the short wavelengths could improve the management of skin disorders (hyperpigmentation, melasma).
For the moment, the first reflex to partially shield blue light is to adopt suitable cosmetics with sunscreen (which can be combined with antioxidants). The synergy with the oral route by GliSODin General State allows to act from the inside, to protect the cells from oxidative stress for a healthier appearance.
