Blue light, also known as high energy visible (HEV) light, is made up of electromagnetic particles that travel in waves.
With a very short wavelength, blue light, which is emitted from smartphones, tablets and computer screens, produces a higher amount of energy, meaning is it able to penetrate more deeply into the skin and cause damage.
“Data shows that blue light induces a potent and long-lasting hyperpigmentation in darker skin types,” Anjali Mahto, Consultant Dermatologist and spokesperson British Skin Foundation, told Cosmetics Business.
“Blue light has also been implicated in premature skin ageing where early studies show it may cause damage via harmful molecules known as free radicals.
“Free radicals can interact with DNA, lipids and proteins in skin cells leading to breakdown of collagen.”
In response, as more consumers work from home during the coronavirus pandemic, brands have jumped at the opportunity to create products that claim to protect consumers’ skin from HEV light.
Here, Cosmetics Business rounds up three ingredients being used by skin care brands to fend off any lasting damage.
