LED Light Therapy Masks

LED masks use light at specific wavelengths. Red light (around 630 to 660 nm) and near-infrared (around 830 to 850 nm) are marketed for fine lines and skin tone; blue light (around 415 nm) is marketed for acne. Results from at-home devices are generally modest and build up over weeks of regular use.

What to check:

• FDA status. Several masks are FDA-cleared for specific uses. "Cleared" is not the same as "approved", and an "FDA-registered" facility claim says nothing about the device itself.
• Wavelengths listed. A trustworthy listing names the exact wavelengths rather than just colours.
• Fit and coverage. Rigid masks hold LEDs at a fixed distance; flexible silicone masks follow the face more closely.
• Eye protection and timer. Look for an automatic shut-off and follow the brand's eye-safety guidance.
• Power. Cordless masks are convenient; corded masks avoid battery wear.

Avoid LED masks if you take light-sensitizing medication or have an eye condition unless a doctor says otherwise. For conventional skincare masks, see face masks.
