As an increasingly popular longevity tool, red-light therapy is said to help improve skin and hair health, enhance cellular vitality, and reverse the signs of aging. While there is evidence to support the claims of red-light therapy, studies are limited. To discover best practice when it comes to red-light therapy and how to make it work into our everyday lives, we asked the experts to share insight into its effectiveness.

How Can I Access Red-Light Therapy?

Red-light therapy has long been used by athletes and wellness professionals to boost recovery and reduce oxidative stress. These days, it’s fast becoming the norm at the local gym and wellness spa too. You'll probably be able to find red-light therapy rooms or “red light stations” there, which make up part of a hot and cold contrast therapy circuit alongside cold plunges and saunas.

Being able to easily access red-light therapy doesn’t stop there. Online, you’ll find numerous brands selling red-light therapy beauty tools designed for home use. Options for red-light therapy include face masks, massage guns, blankets and panels, and even red-light therapy helmets that claims to stimulate hair growth.

For example, the Theragun Pro Plus offers five therapies combined into one with this full-body heated massager that features near-infrared LED light and vibration to give you 15 minutes of massage in just two minutes.
