The skin


Before we introduce the topic of red light therapy, let’s cover what the skin is exactly.


The skin is the largest organ of the body, with a total area of about 20 square feet. It protects us from microbes and other elements, it helps regulate body temperature, and it enables the sensations of touch, heat, and cold.


The skin has three main layers:


  1. The epidermis, the outermost layer of skin, provides a waterproof barrier and creates our skin tone.
  2. The dermis, beneath the epidermis, contains tough connective tissue, hair follicles, and sweat glands.
  3. The deeper subcutaneous tissue (hypodermis) is made of fat and connective tissue.(14)


The different wavelengths of red and near infrared light penetrate different levels of the epidermis.

The closer the wavelength is to infrared light, the deeper it gets into the dermis, being able to target organs, cartilage and even bones.



How does red light therapy work?


If you still haven’t, take a look at What is red light therapy? and How does red light therapy work?

Once you understand how red light therapy affects the cells of the body, and to be more specific in the case of the skin. Here is a brief explanation of what happens.


The powerful wavelengths of red light exposed to the skin, penetrate deep into the tissue and are absorbed by the skin cells. This encourages the production of elastin, fibroblasts and collagen which means that it will reduce the thinning of your skin and prevent wrinkles. Moreover, red light also boosts circulation which brings more nutrients to the skin tissue. This translates into regenerative effects on the cells of the body and helps promote healing of any damaged tissue.


The main three benefits you will notice are:


  • Skin rejuvenation


Red light provides safe and powerful wavelengths of natural light that contain no chemicals, UV rays or excess heat.

To be more concrete, red light therapy improves skin health and appearance helping your cells rejuvenate and heal from the inside out. Many studies have also identified an increase in circulation that not only indicates that the tissue is receiving more oxygen and nutrients, but also that is getting rid of toxic byproducts making the skin look much younger and healthy. (1)


  • Decreased skin inflammation 


The increased blood flow derived from red light exposure also alleviates both acute and chronic inflammation. This increase in blood supply into the damaged cells increases the body’s antioxidant defenses too, producing a natural anti-inflammatory effect.


  • Collagen boost


In addition to improving appearance, boosting circulation and decreasing inflammation, red light therapy also increases collagen production which turns into healthier and younger looking skin.

Collagen is the most abundant protein in our bodies, and it’s critical for skin health, and joint and bone health.

In several studies, researchers have noticed much higher collagen levels in the subjects and patients treated with light therapy, especially with infrared light. (2,3,4,5). 

The boost seen in natural collagen production as a result of red light therapy, is crucial for a younger-looking skin and faster healing properties (6,7,8).

We are going to present a study so you can see how all the benefits we have previously mentioned are scientifically proven and tested. The study mentioned was conducted in 2013 and analysed the effects of red light therapy on 136 people between 27 and 79 years old. They all were exposed to red light twice a week during a period of 15 weeks and the results were extremely positive.


Here’s a summary of the findings:


  • Reduces wrinkles and improves complexion. The subjects treated with red light showed significantly improved skin condition including reduction of wrinkles, fine lines and other signs of aging.
  • Improved skin feeling. After the 30 sessions, nearly every subject in the red light therapy group reported an improvement in their skin felt and look. Some volunteers that decided to continue with red light therapy exposure for another 30 sessions reported continuous improvements.
  • Increased collagen density. Subjects that received red light therapy treatment saw increases in their collagen density compared to the control group, who saw no significant changes. (7)


There is a vast number of peer-reviewed clinical studies that show similar positive effects for wrinkle reduction and skin rejuvenation and complexion, below we mansion a few.


  • Red light therapy for wrinkle reduction

A trial conducted in 2017, selected 30 women of ages between 30-55 and exposed them to red light therapy for 6 weeks. The participants experienced significantly reduced wrinkles around the eyes, and the researchers concluded that red light therapy “had a positive effect on wrinkle and moisture content of adult women’s faces”. (10)


  • Treating sunburn with red light therapy

An excess exposure to sun is known to damage skin and make us appear older, with significant fine lines and wrinkles. A study conducted in 2007 examined the effects of red light therapy in facial sunburn damage. The researchers found that 91% of participants reported improved skin tone and 82% reported enhanced smoothness of skin. Red light once again was found to be especially effective for wrinkles and fine lines around the eyes. (11)


  • Red light for eye wrinkles

In 2008 a study where volunteers did red light therapy treatments twice a week, for a month, saw similar results. Eight weeks after the treatment was completed, researchers evaluated the subjects skin and found that over 70% of them reported lasting and clearly visible improvements in the reduction of fine lines and wrinkles. (9)


  • Improved scar appearance with red light

Many skin injuries such as burns, cuts or surgical scars, are long lasting and usually permanent. A group of researchers looked at the effects of red light on reducing the appearance of scars, and found it a good treatment to reduce the visibility of scarring and to decrease the prominence of raised scars. (12)


Lastly, we are going to mention a common condition amongst society, acne.

  • Red light therapy for Acne

In 2013 a group of researchers highlighted a few studies that showed red and near-infrared light to be effective for treating acne. They noted that red light exposure has an impact on sebum production which contributes to acne, in addition to controlling cytokines, which impact skin inflammation. (6)


A 2008 trial also treated a group of 15 women with moderate acne vulgaris with red light therapy twice a week for four weeks, and saw significant reduction of acne and decrease of sebum excretion. Positive effects were still apparent then the women returned 3 months later for a follow up. (13)



To conclude, as you can see, several studies have demonstrated how red light therapy reduces inflammation and wrinkles, and also helps in healing and rejuvenating the skin. 

A safe and natural skin treatment that is gaining popularity amongst celebrities, and dermatologists all over the world.
