Red light therapy (RLT) is a non-invasive, painless treatment that uses low-intensity red and near-infrared light to stimulate healing in the body. It has been used for a variety of medical and cosmetic conditions, including skin problems, scarring, wrinkles, age spots, and alopecia. Studies have shown that red light therapy can help improve skin health, stimulate collagen production, and even treat full facial wrinkles. It is also believed to be beneficial for muscle tissue and other parts of the body.
Although red light therapy is generally safe, it is important to talk to your doctor before trying it. Some salons and dental offices offer RLT treatments, but it is best to get it done in a doctor's office. Home treatments may cause side effects or injury. Additionally, adequate eye protection may be necessary during red light therapy.
In this article, we will discuss the benefits of red light therapy and how it works. We will also provide tips on how to find a qualified practitioner and what to expect during a treatment session.
What Is Red Light Therapy?Red light therapy (RLT) is a form of photobiomodulation or a treatment that uses light-emitting diodes (LEDs) or low-level laser therapy to stimulate cellular activity and achieve therapeutic benefits. It sends low-intensity red and near-infrared light to body cells to stimulate healing. This red light is natural and can penetrate deep into the skin, where cells can absorb and use it. The use of red light therapy as an anti-aging treatment was first studied by NASA in the 1990s.
Scientists discovered that intense light from red light-emitting diodes (LEDs) helped promote plant cell growth and photosynthesis. Since then, many experts have studied the effects of RLT on humans and believe it can help with a variety of medical and cosmetic conditions.
Benefits of Red Light TherapyRed light therapy has been used for a variety of reasons, including in the treatment of skin, dental, and inflammatory conditions. Many experts believe it can help with problems such as skin conditions, scarring, and signs of aging, including wrinkles and age spots. Studies have shown that RLT can help improve skin health by increasing blood flow to the surface of the skin being treated. This increased blood flow delivers more nutrients to that area, which can help reduce inflammation and promote healing.
Additionally, RLT can help stimulate collagen production, thus preventing the development of stretch marks. A small study published in the Journal of Cosmetic and Laser Therapy explored the effect of low-level light on people with alopecia. The study found that RLT was effective in promoting hair growth in those with alopecia areata.
How To Find A Qualified PractitionerIf you are considering red light therapy, it is important to find a qualified practitioner who can provide safe treatments. A dermatologist can make sure that the skin condition is what you think it is and can discuss the merits of red light therapy and other treatment options. It is also important to research any practitioner you are considering before making an appointment. Make sure they have experience with RLT treatments and ask for references from previous clients if possible.
What To Expect During A Treatment SessionMost RLT treatments last between 10-30 minutes depending on the area being treated.
During the session, you will be asked to sit or lie down while the practitioner applies the device to your skin. You may feel a slight warmth or tingling sensation during the treatment but no pain. Experts say you're likely to see some skin improvement effects with red light therapy, but as with most skin rejuvenation treatments, most visible results will be temporary.
ConclusionRed light therapy is a safe and non-invasive treatment that has been used for a variety of medical and cosmetic conditions. It can help improve skin health by increasing blood flow to the surface of the skin being treated and stimulating collagen production. Additionally, studies have shown that RLT can be effective in promoting hair growth in those with alopecia areata. If you are considering red light therapy, it is important to talk to your doctor first and find a qualified practitioner who can provide safe treatments.
