Red light therapy has been gaining popularity since the late 1980s when NASA scientists noticed that wounds seemed to heal more quickly under red and blue LEDs used for plant growth experiments. Today, red light therapy is commonly used in medi spas and homes as a noninvasive treatment that can reduce inflammation and promote collagen production and density. This can lead to improved skin texture, reduced wrinkles, and even help with conditions like pattern hair loss and alopecia, as well as reducing body fat.
The benefits of red light therapy extend to a variety of skin concerns, including scarring, fine lines, wrinkles, and acne. The therapy works by stimulating regeneration, healing, and repair of skin cells, enhancing collagen production, and improving skin elasticity. The treatment can also help dial down inflammation, reducing redness and potentially alleviating pain and soreness in deeper tissues. Red light therapy is often combined with other treatments like microneedling, chemical peels, or laser treatments for enhanced results.
The frequency and duration of red light therapy sessions depend on the type of device used. In-office devices are more powerful than at-home devices, which are FDA-cleared for safety and effectiveness. For at-home devices, it is recommended to use them regularly, either daily or 3-4 times per week, for at least 6 weeks to allow the device to work. Skin-firming results may require up to three months of consistent red light therapy. While some benefits such as collagen boosting may take a few months to notice, red light therapy can calm inflammation in a single 10-minute session, according to dermatologists.
Red light therapy is generally considered safe for all skin types, but there are some common sense precautions to take. It is important to close your eyes during the treatment to avoid potential damage. While the therapy is noninvasive and should not involve any heat, it is always recommended to consult with a dermatologist or skincare professional before starting any new treatment. Red light therapy is an effective way to address a variety of skin concerns, from signs of aging to inflammation and pain relief, making it a versatile and beneficial treatment option for many individuals.
