For every skincare must-have, like cleanser (important for removing makeup, oil and daily grime) and sunscreen (for protecting skin against damaging UV rays), there is a rather dubious product on the market. One of them is blue light skincare, which professes to protect skin against the light emitted from laptop and phone screens. Right now, there isn’t much evidence to confirm that blue light is actually a threat to skin, unlike UV, which can cause cancer and accelerate the signs of aging. As a result, beauty lovers everywhere are questioning product claims. Just last year, influencers Valkyrae and Addison Rae went viral for all the wrong reasons when they advertised blue light skincare, with people on social media calling them out for backing a “scam product”.
