@nkim.skincare: Before using an LED face mask, check your medicines and topical treatments. Some can increase light sensitivity—but wavelength matters, so don’t rely on generic online lists. Check the medicine leaflet and your exact mask instructions. Never stop prescribed medicine without advice. Ask a pharmacist or GP if you’re uncertain.
