Red Light Therapy (RLT) for the Skin: How It Works and The Benefits

Red light therapy is a non-invasive, painless and effective way to improve skin health. It uses low wavelengths of red light to stimulate cell activity, increase blood flow and reduce inflammation, which can help improve several skin conditions. In this blog post we take a closer look at how red light therapy works, its benefits, and scientific studies that support its use.

How Does Red Light Therapy Work?

Red light therapy uses low wavelengths of red light that penetrate deep into the skin to promote cell activity. The light energy is absorbed by the mitochondria in the cells, which then produce more ATP (adenosine triphosphate), a molecule that provides the cells with energy. This increase in ATP production can stimulate cell regeneration, promote blood circulation and reduce inflammation, all of which are beneficial to the skin.

With a wavelength of 660 nm, the skin is stimulated to produce fibroblasts , the cells responsible for the production of collagen and elastin. This wavelength is particularly effective at reducing wrinkles and fine lines, making the skin look younger and more radiant.

Wavelengths of 850 nm also have several benefits for the skin. It stimulates the production of ATP in the cells, giving the skin more energy . It helps the skin repair from damage and reduces inflammation, improving the appearance of the skin.

Benefits of Red Light Therapy for The Skin

1. Reduces fine lines and wrinkles
   Red light therapy has been shown to stimulate collagen production, which can help reduce fine lines and wrinkles. Collagen is a protein that gives the skin its elasticity, and as we age our collagen production decreases, leading to sagging and wrinkles. A study published in the Journal of Cosmetic and Laser Therapy found that red light therapy can increase collagen production and improve skin texture and tone.
2. Improves the complexion and texture of the skin
   Red light therapy can also improve skin tone and texture by increasing blood flow and stimulating cell activity. It can help reduce hyperpigmentation, sun spots and age spots, resulting in smoother, more even-toned skin.
3. Treats acne
   Red light therapy has been shown to be effective in treating acne by reducing inflammation and killing acne-causing bacteria. A study published in the Journal of Investigative Dermatology found that red light therapy can significantly reduce acne lesions and improve overall skin texture.
4. Helps heal wounds and scars
   Red light therapy can also help speed the healing of wounds and scars by increasing blood flow and stimulating cell activity. A study published in the Journal of Clinical and Aesthetic Dermatology found that red light therapy can improve the appearance of scars by increasing collagen production and promoting cell growth.
5. Reduces inflammation
   Inflammation is a leading cause of many skin conditions, including acne, rosacea and psoriasis. Red light therapy can help reduce inflammation by increasing blood flow and stimulating cell activity. A study published in the Journal of Investigative Dermatology found that red light therapy can significantly reduce inflammation in skin cells.

Scientific studies supporting the use of red light therapy for the skin

• A study published in the Journal of Cosmetic and Laser Therapy found that red light therapy can significantly improve skin texture, reduce fine lines and wrinkles, and increase collagen production.

• Another study published in the Journal of Investigative Dermatology found that red light therapy can significantly reduce acne lesions and improve overall skin texture.

• A study published in the Journal of Clinical and Aesthetic Dermatology found that red light therapy can improve the appearance of scars by increasing collagen production and promoting cell growth.

• A study published in the Journal of Investigative Dermatology found that red light therapy can significantly reduce inflammation in skin cells.

Conclusion

Red light therapy is a safe, non-invasive and effective way to improve skin health. It can help reduce fine lines and wrinkles, improve skin tone and texture, treat acne, heal wounds and scars, and reduce inflammation. Scientific studies support the use of red light therapy for the skin, and it is becoming an increasingly popular treatment option for people looking to improve their skin.
