LED Face Mask Side Effects: What's Real and What's Not
A short list of real risks and a longer list of myths.
January 14, 2025 · The Radia Atelier
LED therapy has one of the cleanest safety records in modern skincare. But "clean" is not "zero risk." Here is what to watch for.
Real, documented effects
- Temporary mild warmth or redness after a session.
- Eye strain if you do not use proper eye protection.
- Possible worsening of melasma in some users — choose red and near-infrared only if you have melasma.
- Photosensitivity if you are on isotretinoin, certain antibiotics, or photosensitising herbal supplements.
Myths
- "LED light causes skin cancer." It does not. Red and near-infrared LEDs do not emit UV.
- "It dries out your skin." LED therapy is non-thermal and does not affect skin barrier moisture.
- "It is bad for your eyes through closed eyelids." Closed eyelids plus integrated eye pads provide complete protection.
