Red light therapy (RLT) is a non-invasive skincare treatment that uses specific wavelengths of light to enhance skin health, promote healing, and rejuvenate tissues. It has gained widespread popularity due to its scientifically-backed benefits for a variety of skin concerns, including anti-aging, acne, and inflammation.
In this article, we’ll explore how red light therapy works and its numerous benefits, as well as compare two highly rated products to help you choose the right device for your needs.
What exactly is red light therapy?
It’s a non-invasive treatment that uses red or near-infrared light. Also called photobiomodulation, a few dermatologists offer it to treat acne, signs of aging like wrinkles, hair loss, and other conditions. The red light that dermatologists offer is more powerful than that found in devices sold for at-home use.
To give their patients the best results, dermatologists typically recommend red light as a complementary therapy. This means, it’s part of a treatment plan that uses standard therapy. For example, when treating signs of aging, your dermatologist may add red light to a treatment plan that includes a medicated cream, microneedling, or a chemical peel. Tailored skin care may also be part of this treatment plan.
To help you maintain results after in-office treatment, your dermatologist may recommend using an at-home red-light device.
Whether you want to use red light after receiving treatment from a dermatologist or to try it on your own, you’ll find plenty of options. Red-light wands, masks, and other devices are sold for treating the skin. Caps, combs, and helmets are sold for regrowing hair. Most at-home devices contain light emitting diodes (LED), which are considered safe for home use. You’ll also find devices sold for at-home use that have low-level lasers.
How Does Red Light Therapy Work?
Red light therapy works by delivering specific wavelengths of light—primarily in the red and near-infrared spectrum—into the skin’s deeper layers. These wavelengths stimulate the mitochondria in cells, which are responsible for energy production. By boosting cellular energy, red light therapy helps to:
-
Stimulate collagen production – essential for skin elasticity and youthful appearance.
-
Reduce inflammation – helps with conditions like acne and rosacea.
-
Improve blood circulation – enhances oxygen and nutrient delivery to skin cells.
-
Speed up tissue repair – promotes healing and reduces scarring.
Key Benefits of Red Light Therapy:
-
Anti-Aging: Reduces the appearance of wrinkles, fine lines, and sagging skin by stimulating collagen production.
-
Acne Treatment: Helps kill acne-causing bacteria and reduces inflammation in the skin.
-
Skin Rejuvenation: Improves skin tone, texture, and overall radiance by boosting cellular activity.
-
Healing and Recovery: Speeds up the recovery process for scars, wounds, and even sunburns.
-
Pain Relief: Helps alleviate joint pain, muscle soreness, and minor injuries by increasing circulation and reducing inflammation.
