Blue defenders
The beauty industry loves a new skin scourge to target… increasingly we’re hearing about the impact that HEV (high energy visible) light, also known as blue light, can have on the complexion. Although UV rays from the sun are proven to have the most detrimental effect, a number of studies show that blue light emitted from cellphone and computer screens may play a part in causing hyperpigmentation, inflammation and damage to the skin barrier. Although large, wide-scale studies on the long-term effects are yet to be undertaken, recent indications deserve consideration. Skincare brands have been quick to respond by producing or reformulating products designed to help, with increased antioxidants and, in some cases, melanin derivatives.
