Acne and red light therapy (RLT)

People with acne need a good skincare routine to combat acne and treat their skin. Nowadays, there is a new, very promising, and scientifically proven therapy: red light phototherapy. The good news is that phototherapy is painless, non-invasive, and has no side effects.

Professional at-home treatments with red light, devices, and LED have incredible benefits for the skin. They help increase collagen production, improve skin firmness and elasticity, and enhance its texture. The combination of blue and red light therapy on the skin can help eliminate acne, prevent the formation of new acne, reduce cysts, and remove blackheads and whiteheads.

Scientific evidence
According to the Journal of Dermatologic Surgery by Dae Hun Shu, visible light, including red light therapy, is an effective solution in the treatment of mild to moderate acne. Red light phototherapy on the skin can help improve inflammatory and non-inflammatory lesions and acne.

Dr. Engelman Dendy, a qualified dermatologist from Manhattan, explains that the combination of red light therapy and blue light therapy is an effective solution for acne. Dr. Dendy further explains that blue light acts on the upper layer of the skin to eliminate acne-causing bacteria, clean the pores, and regulate oil production. Red light phototherapy, on the other hand, penetrates deeply into the skin to reduce inflammation caused by acne.

A study conducted by Jiahua Li and published in Photodermatology, Photoimmunology, and Photomedicine compares the efficacy of red and blue light in the treatment of acne vulgaris. The study shows that both treatments are effective and safe methods for curing acne. Red light therapy has many benefits and fewer side effects.

People are becoming increasingly aware of the use of red light phototherapy on the skin and its transformative effects on various skin conditions. Dr. Azza Halim, a qualified anesthesiologist, explains that several social media platforms are making red light therapy a popular form of treatment.

Does blue light phototherapy work against acne?
Blue light phototherapy is a safe, painless, and non-invasive form of laser treatment. Blue light acts on the upper layer of the skin to eliminate acne-causing bacteria, clean pores, and regulate oil production. Blue light does not contain ultraviolet radiation and has mild side effects on the skin. The American Academy of Dermatology supports the effectiveness of laser and other forms of phototherapy in the treatment of acne. Although results may vary from person to person, individuals who have used blue light have reported significant improvements in their acne. Acne disappeared, the skin became more even and clear, and no new acne formed.

The Journal of Dermatologic Science by Akira Kawada reveals that the use of high-intensity blue light therapy is effective for treating mild to moderate acne. Patients treated with blue light reported a reduction in lesions and acne in about 5 weeks.
Blue light therapy is safe when used according to recommendations, contains no drugs, has no adverse side effects, is harmless to all parts of the body, eliminates acne-causing bacteria, and does not leave scars on the skin.

How does red light phototherapy work to improve acne?
Red light phototherapy uses light technology to achieve therapeutic benefits, anti-inflammatory effects, and skin wound healing. Red light phototherapy can help with skin conditions such as severe acne, vulgar acne, and inflammatory acne.

Red light phototherapy uses wavelengths that penetrate deeply into the skin to improve blood circulation, reduce inflammation, and stimulate cellular activity. The process is used to treat acne and skin lesions and enhance healing. Red light therapy not only treats acne but is also promising for improving the appearance of acne scars.

Susan Pei's Indian Dermatology Online Journal supports that the use of laser and light therapies is effective in the treatment of acne vulgaris because it is safe and has fewer complications. The study further states that red light therapy may help with chronic inflammatory acne in adolescents and adults.

Additionally, red light phototherapy can promote skin rejuvenation, increase collagen production, and prevent acne scars. Consistent treatment with red light can aid in wound healing and treat acne depending on its severity.

The science behind blue light and red light phototherapy for acne
One of the greatest benefits of red light phototherapy for the skin is that there is scientific evidence supporting its effectiveness. The power of red light phototherapy in the treatment of acne is backed by cutting-edge research. Studies have shown that red light phototherapy uses light with a wavelength of 620 nm to 720 nm.

Penetrates deeply into the skin down to the tissues and sebaceous glands. Treats severe acne, regulates oil production, reduces the appearance of scars, and prevents the emergence of new pimples. Red light phototherapy can also increase collagen production and improve blood circulation.

The blue light, for its part, combats propionibacteria, the bacteria that cause acne on the skin. As the bacteria are sensitive to blue light, they are effectively reduced to prevent acne outbreaks. In her research, published in Annals of Family Medicine, Anna Mae Scott explains that blue light therapy is an alternative method for treating acne compared to antibiotics.

Combination of blue and red light
The combination of red light therapy and blue light therapy works well for common acne and inflammatory acne. Red light penetrates deeply into the skin to soothe inflammation and improve wound healing, while blue light acts on the epidermis to eliminate acne-causing bacteria.

Susan Pei's Indian Dermatology Online Journal supports that red light and blue light, approved by the FDA, act effectively on lesions and acne when combined. The blue light has a wavelength of 415 nm to act on the dermis, while the red light has a wavelength of 630 nm to penetrate deeply into the skin.

Actress Julianne Moore incorporates phototherapy into her skincare routine and advocates for innovative practices in this field. Moore, known for her radiant complexion, attributes her success in skincare to the strategic use of red light phototherapy devices. Her efforts align with the growing trend of red light phototherapy for various skin conditions.

Can RLT cause cancer?
There may be concern about the risk of skin cancer with any form of phototherapy. RLT is not associated with an increased risk of skin cancer. This therapy differs significantly from exposure to UV light, which is known to contribute to skin cancer.

Conclusion
Acne is a common skin condition that can be treated with oral and topical treatments, including LED phototherapy. Phototherapy is a safe and innovative form of treatment for people with mild to severe acne.

Using red light, blue light, or a combination of both can help control acne. This is because these two lights act differently to combat acne as they use light of different wavelengths. The good news is that phototherapy is painless, non-invasive, and does not cause side effects.
