The Best Blue & Green Light Therapy Devices for Reduced Acne & Glowing Skin, According to a Dermatologist

What Features Should You Look for In an At-Home Blue Light Therapy Device & Green Light Therapy Device?

If you’re interested in investing in an at-home light therapy device, Dr. Hartman recommends looking at the light wavelength number, because at-home light therapy wands and masks are most effective at certain wavelengths. Dr. Hartman recommends, “For blue light, you want to look for wavelengths between 415 – 480 nanometers. For green light, look for devices that provide green light around 525 nanometers.” Not all devices advertise their wavelength range, but for those that do, I noted them below.

It’s also important to consider the design of the device, how it’s powered, and what will work better with your lifestyle, as well as if it comes with a convenient case for bringing your LED light therapy on the go. And, if you want more than blue or green light options, look into a device that provides microcurrents or red light, as well.
