What is Red Light Therapy?

Red light therapy is one form of phototherapy that utilizes (LED) light therapy to treat medical and cosmetic conditions. RLT goes by other names like soft laser therapy, low-level laser light therapy, and cold laser therapy. One significant benefit of red light therapy is that it is a non-invasive skin treatment. Red Light Therapy is not a one-and-done treatment and must be consistently used to see results. 

The wavelength is what determines how deeply the light will penetrate your skin. Red light therapy has different forms, including masks that fasten to the face, wands, or handheld devices. 

How Does Red Light Therapy Work?

Our cells become less effective at producing energy as we age, and we have reduced collagen production. Red light therapy has shown much promise in healing, repairing skin conditions, and stimulating cells to help counteract aging. 

It sends low-intensity light into the skin to stimulate new cell growth and help repair skin, improve psoriasis, improve rosacea, heal acne, reduce stretch marks, and rejuvenate the skin. Red light therapy is known to penetrate better than all other LED therapies.

Benefits of Using Red Light Therapy

One significant benefit to using red light therapy is that there is virtually no downtown, which substantially benefits clients who don’t have the luxury of taking time off from work to get cosmetic procedures done. It’s available at most med spas and carried by many beauty supply stores as an at-home device. It’s an excellent treatment if you have an event to go to but want to avoid another more invasive treatment that needs significant downtime to recover. Red light therapy may be a safer alternative for some people who cannot use lasers for skin treatments. It’s safe to use on most skin types, but as with anything new, it’s best to talk with your healthcare provider about your skin specifically. 

Red light therapy can decrease inflammation, speed up healing time, and improve scars for someone who suffers from acne, eczema, and psoriasis. 

For more mature skin, red light therapy can help stimulate collagen production to help wrinkles, fine lines, sagging skin, and sun damage.

In the case of Rosacea, it can help with inflammation and be used in conjunction with other LED therapy to get the most benefits. 

At-Home Red Light Therapy devices 

These devices are generally less potent than devices at a medical office. 

Make sure always to protect your eyes when using any of these devices. It’s important to note that more is not better with these types of devices, and always follow whatever time frames the manufacturer recommends. 

Cost of Red Light Therapy and Cautions 

Cost may vary significantly for this type of therapy depending on where you go. It could cost anywhere from $150 to $300 per session, and at-home devices can cost $200 to $2000. Misusing a device can cause unwanted harm to your skin. Many devices are on the market now in different forms, like wands or masks. These devices are used for specific periods to get the needed results. If you have or are prone to hyperpigmentation, make sure to mention that to your doctor or esthetician. Licensed professionals perform treatments in a medical office with medical-grade devices that are more intense than at-home devices.

Red Light Therapy and Thinning Hair

Red light therapy shows promise in treating thinning hair by stimulating hair growth. 


As with most treatments, your results are temporary, and you must keep up to see results. The benefits from treatments are cumulative and work together with other therapies, such as anti-aging creams, masks, retinol, peels, and sunscreens. 

Final thoughts

It’s important to know what treatments are out there that will work for your skin. The best results come from a combination of facial treatments with results-driven, pharmaceutical-grade skincare that targets your specific needs.
