Blue light is all around and it’s do­ing your skin no favours

The Sunday Telegraph (Sydney) - Stellar - - Contents - by Sher­ine Youssef

Coun­ter­act the harm­ful ef­fects of blue light.

High-en­ergy vis­i­ble blue light (HEV), which makes up the blue light part of the elec­tro­mag­netic spec­trum, is vi­tal – after all, it helps boost our me­mory, mood and alert­ness.

The sun pro­vides enough HEV ex­po­sure, but in the dig­i­tal age there’s no es­cap­ing an ex­tra dose. Smart­phones, lap­tops, com­put­ers, tele­vi­sions and en­ergy-ef­fi­cient light­ing all emit HEV and may wreak havoc on our skin.

“HEV light can pen­e­trate to the der­mis – deeper than both UVA and UVB light – where it can lead to pre­ma­ture age­ing, hyper-pig­men­ta­tion, wrin­kles and a loss of elas­tic­ity and firm­ing,” says Ocinium founder Cas­san­dra Hilton. “Con­stantly con­nected mil­len­ni­als are at in­creased risk, as are darker skin types who have ex­hib­ited a re­lapse and wors­en­ing of pig­men­ta­tion and melasma when ex­posed to blue light.”

Your best de­fence is an an­tiox­i­dant serum (look for ones with vi­ta­mins A, B3, C and/or E) and a sun­screen with a phys­i­cal shield, such as zinc ox­ide or ti­ta­nium diox­ide, which help pro­tect skin against HEV’S dam­ag­ing ef­fects.

Hilton also sug­gests a blue-light screen fil­ter for your com­puter, en­abling night mode on phones to pro­tect eyes and avoid­ing dig­i­tal de­vices be­fore bed as “ex­po­sure to blue light is as­so­ci­ated with al­tered cir­ca­dian rhythms, which im­pacts bi­o­log­i­cal skin func­tions of DNA re­pair, im­mu­nity and re­ju­ve­na­tion”.
