LED (light-emitting diode) masks use specific wavelengths of light that penetrate deep into the skin to stimulate natural repair processes, says Joshua Zeichner, MD, a board-certified dermatologist and associate professor of dermatology at Mount Sinai Hospital in New York City. This can help improve skin texture, tone, and elasticity, while addressing concerns like acne (and acne scars), dark spots, rosacea, eczema, hyperpigmentation, redness, fine lines, wrinkles, and even psoriasis.
You might be wondering, “Do they actually work?” Well, according to numerous studies “LED light therapy can aid in skin healing, improve chronic conditions like acne and rosacea, and enhance overall skin health,” says Viktoryia Kazlosukaya, MD, PhD, a board-certified dermatologist in New York City. “That said, the results are often modest and gradual. It’s essential to set realistic expectations—LED masks are not a substitute for professional skin care, cosmetic procedures performed by board-certified dermatologists, or prescription medications. They are best viewed as a supplementary tool in a broader skin care routine.”
