Overview

Red light is one of the most powerful colors to improve blood circulation and stimulate skin cells to secrete collagen.

Red Light Therapy (RLT) aims to address skin problems by using low wavelength red light. Many experts believe it can help with problems such as skin conditions, scars, and signs of aging, including wrinkles and age spots. The possibility of using RLT as a way to rejuvenate the skin has led to a lot of research.

What is red light therapy?

Red light therapy is a form of photo biomodulation or a treatment that uses light-emitting diodes (LED) or low-level laser therapy to stimulate cellular activity to achieve therapeutic benefits. It has been proven that the right wavelength of red light is beneficial in producing cellular changes that contribute to the production of collagen, which is vital in combating saggy and loose skin.

Light emitting diode (LED) light therapy is growing in popularity in both aesthetician offices and at home. Using varying LED wavelengths, this skincare technique purportedly helps:

  • treat acne
  • reduce inflammation
  • promote anti-aging effects

How does red light therapy work?

With red light therapy, you expose your skin to a lamp, device, or laser with a red light. A part of your cells called mitochondria, sometimes called the “power generators” of your cells, soak it up and make more energy. Some experts think this helps cells repair themselves and become healthier. This spurs healing in skin and muscle tissue.

The special light penetrates into the skin to increase the production of human collagen. Collagen light reaches the deepest layer of the skin, the dermis. When light hits the skin, the epidermis absorbs the light, which stimulates collagen.

The light seems to penetrate deep into the skin and affect sebum production as well as reduce inflammation and irritation in that area. The red LED also reduces inflammation by improving circulation, which can give you a healthier glow. 

What does red light therapy treat?

Research shows RLT may smooth your skin and help with wrinkles. RLT also helps with acne scars, burns, and signs of UV sun damage.

It will help you increase collagen production and improve its density, eliminate fine lines and wrinkles, and eliminate common skin problems. For skin wounds, stretch marks and light scars, treatment with red light for 10-20 minutes 3-5 times a week for 1-4 months will stimulate collagen production and reduce the appearance of scars.

In fact, Dr. Jagdeo says red light therapy has several proven benefits and is most commonly used to treat signs of aging skin such as wrinkles, hair regrowth and acne, and the list may still grow.

What are the benefits of red light therapy?

Light stimulates blood circulation, which also leads to an increase in the activity of the lymphatic system, which promotes the outflow of interstitial fluid from tissues and transports leukocytes to those areas where they are needed.

Increases oxygenation of the skin and improves blood circulation, as well as repairs damaged tissues.

One of the most popular uses of red light therapy is for its anti-aging benefits, and for good reason: There are an abundance of studies to support its positive anti-aging effects. A 2019 study from The Journal of The American Academy Of Dermatology found that red light therapy increases production of collagen, elastin, and hyaluronic acid in the skin. This, in turn, can help with skin laxity, fine lines, pore size, texture, and wrinkles, making low-level red and infrared light treatments ideal "opportunities for daily, at-home treatments for patients with photo-aging and photo-damaged skin."

Does RLT have risks?

Red light therapy is generally considered safe, even though researchers aren’t exactly sure how and why it works. And there are no set rules on how much light to use. Too much light may damage skin tissue, but too little might not work as well.

Takeaway

RLT is generally safe and may be a very effective treatment option for people seeking smaller changes in their skin or to keep the skin healthy and reduce inflammation.

RLT has shown promising results in treating some skin conditions. Based on the current research, you may find that RLT is a good tool to add to your skin care regimen. just make sure the  home device you buy has the proof to back it up. And promise you'll read the instructions before you use it over your face.
