清晨朗读会

LED masks feature eye and mouth holes and are typically held in place with straps. Hand-held wands are lightly pressed against the skin and slowly moved around. Both bathe the skin in various wavelengths of light, depending on what they’re trying to accomplish.
Many devices emit red light with wavelengths between 630 and 700 nanometers. Red light can penetrate deeply into the skin to boost the production of collagen and elastin, proteins that help to maintain skin’s strength and elasticity, said Dr. Akshay Sanan, a facial plastic surgeon in Boston. By boosting those proteins, red light may minimize wrinkles and help skin appear younger. It can also “reduce inflammation and accelerate healing,” Dr. Sanan said.
