The healing results of light therapy are absolutely nothing new– it was first utilized in the late 1800s to treat skin tuberculosis (TB), and NASA used it in the 1980s to grow plants in deep space. Fast forward to the modern-day, and light therapy seems to be popping up everywhere in expert skin care treatments and at-home devices.

Below, we break down whatever you need to know prior to going under the red lights.

What is Red Light Therapy, and How Does It Work?

Traffic signal therapy uses a particular natural wavelength of light for healing benefits, both medical and cosmetic. It is a mix of light-emitting diode (LED) that discharges infrared light and heat.

Skin Specialist Lindsey Zubritsky, MD, discusses that there is a spectrum– ranging from ultraviolet (UV) rays and infrared (things we can’t see) to noticeable light– when it concerns wavelengths of light (colors of the rainbow). Traffic signal therapy makes use of low wavelengths of traffic signal as a treatment since, at this specific wavelength, it is considered bio-active in people cells and can straight and particularly impact and improve cellular function.

( It’s crucial to keep in mind that this specific type of light is not the like UV rays from the sun or what is discovered in tanning beds, and there is no increased danger of skin cancer or UV damage.).

Traffic signal can permeate our top layer of skin and into the deep levels of skin called the dermis. This is where our collagen, elastin, and other vital proteins live. Red light photons are absorbed by our cells and transformed to energy. This energy produced can then promote the production of adenosine, elastin, and collagen triphosphate (ATP), which creates more energy for your cells to utilize. It increases oxygenation to your skin and improves blood circulation while likewise fixing damaged tissue; this leads to enhanced skin texture from increased collagen production and oxygenation.

Traffic signal also has the unique capability to decrease swelling and bacteria, and even treat pre-cancerous lesions says Zubritsky.

A 2019 research study from The Journal of The American Academy Of Dermatology discovered that traffic signal therapy increases production of collagen, elastin, and hyaluronic acid in the skin. This, in turn, can aid with skin laxity, great lines, pore size, texture, and wrinkles, making low-level red and infrared light treatments perfect “opportunities for everyday, at-home treatments for clients with photo-aging and photo-damaged skin.”.

Wound Healing.

The science is not yet totally understood, one hypothesis is that low-level light treatment “appears to improve the natural immune reaction against skin infection by increasing main cytokines that are triggered quickly after bacterial or viral intrusion.”.

Loss of hair.

If you intend on utilizing red light therapy in your home, ensure you do your homework while trying to find gadgets, specifically with numerous on the market. The sweet spot for both cosmetic and restorative advantages is between the mid-600 to 900 nanometer.

The jury is still out on the precise ideal frequency for traffic signal therapy, but it’s most commonly recommended that the lights are pointed at the skin several inches away for a variety of minutes, depending upon the maker’s directions. The treatments are pain-free and need no downtime. The advantages are cumulative, so it’s important to correspond to enjoy all the advantages, which can often take four to six weeks to reveal.

However, it can not absolutely clear particular kinds of acne like cystic acne.

Lots of research studies support red light therapy as an effective treatment modality in treating pre-cancerous sores like actinic keratoses. It’s generally used with a topical photosensitizer to be effective.
