FAQ

Do red light therapy masks work for wrinkles?

Small randomized trials found improvements: in a 2007 trial of 76 people, wrinkles improved about 26–36% vs baseline after 4 weeks of twice-weekly sessions, with no change in the sham group. A 2025 home-mask trial was funded by the maker.

How often should you use an LED mask?

Trial schedules ranged from twice a week for 4 weeks to regular home use over 16 weeks. In a 2025 trial of 95 women, 3 sessions a week were no better than 2. Follow your device instructions.

What wavelengths should an LED mask have?

The trials used red light around 630–660 nm and near-infrared around 830–850 nm.

Are LED masks safe for eyes?

Follow the eye-protection instructions for your device. If you take photosensitizing medication or have an eye condition, ask your doctor first.
