LED Masks for Dark Spots and Hyperpigmentation: The Truth
Where LED helps pigmentation, and where it does not.
January 14, 2025 · The Radia Atelier
Not all dark spots are the same. LED therapy helps some types and is contraindicated for others. Diagnosing the type is step one.
Post-inflammatory hyperpigmentation
Brown marks left behind by acne or eczema. LED red and near-infrared reduce the inflammation that drives PIH and speed clearance. Good fit.
Sun spots and freckles
LED is not a depigmentation tool. Use targeted ingredients (tranexamic acid, kojic acid, azelaic acid) or in-clinic IPL.
Melasma — caution
High-intensity visible light can worsen melasma. If you have melasma, stick to red and near-infrared masks (no yellow or blue light) and consult a dermatologist.
