LED Light Therapy has gained significant attention from experts and researchers for its potential benefits in treating various skin conditions and promoting overall skin health.

Absolutely, experts say. "They work by sending light waves deep into the skin barrier to trigger intracellular reactions, which vary based on the wavelength of light used,"says dermatologist Dendy Engelman, MD. The benefits depend on the color of the light because each will penetrate the skin at different depths, adds Dr. Camp.

The mitochondria in your cells absorb energy from different wavelengths of light—blue, red, and near-infrared—which penetrate the skin at varying depths. Blue light targets the surface/epidermis, treating acne and reducing inflammation. Red light reaches the soft tissue/dermis, boosting collagen production and aiding skin repair. Near-infrared light penetrates deep tissue/hypodermis, supporting muscle recovery and pain relief. By activating cells at these levels, light therapy enhances healing, reduces inflammation, and promotes overall cellular function, says dermatologist Anna Guanche, MD.

"LED light therapy is not an invasive treatment, and when done properly, the risks are minimal," Dr. Ansel says. A 2018 studyin the Journal of Clinical and Aesthetic Dermatologypoints out that this treatment has an "excellent" safety profile,shel adds. While they're safe to use on the skin, there's some concern about damage to the eyes with these lights. So, it's a good idea to wear goggles to help protect them according to Dr Engelman

Individuals who are photosensitive or have connective tissue conditions should either skip LED light therapy or approach it with caution, advises Dr. Ansell. For those of you that can use one, Dr. Engelman suggests wearing it for 15 to 30 minutes a few times a week, but it's crucial to refer to your specific mask's instructions for the recommended time.
