In this therapy, low-power red laser light is used to activate a photosensitizer drug. The interaction creates a chemical reaction that destroys cells. It's used to treat some skin conditions, including skin cancer and psoriasis, acne and warts, and other types of cancer.
Optimal Wavelength
Research suggests that light wavelengths ranging from 660-670 nm and 830-850 nm are in the range that has the most impact on the cellular respiration process while providing the highest level of light absorption.
The most commonly used wavelength for red light therapy is 660nm, which is within this range. This wavelength has been shown to penetrate deep into the skin and tissues, promoting blood flow and pain relief. Other effective wavelengths for red light therapy include 630nm and 850nm.
More good news. Yellow LED Light Therapy boosts the immune system by boosting the flow of our lymphatic system. Rosacea sufferers are prone to secondary skin infections such as acne so exposure to Yellow LED Light Therapy can help heal infections and to revitalise damaged tissue, resulting in healthy and happy skin.
Red LED light therapy may reduce inflammation and stimulate the production of collagen, a protein responsible for younger-looking skin that diminishes with age. Blue LED light therapy may destroy acne-causing bacteria (P. acnes).
The anti-aging hero is red light. Red light increases production of collagen and elastin to fight sagging skin, reduce wrinkles and improve tone and firmness. Read more about the benefits of red light.

Green LED is a favorite for those suffering from hyperpigmentation issues. Those with melasma have the hardest time reducing discoloration because the pigment resides in the upper dermis of the skin and is triggered by hormones.
Fair Skin with Cool Undertones: Cherry, ruby, scarlet, and apple would add warmth to the skin. These shades lie between the bright and dark shades of red to avoid harshness. Fair Skin with Naturally Red Hair: The cool, brighter candy red will play up red hair in the best way!
Who should not use red light therapy? People who take medications that increase their skin or eye sensitivity should not use red light therapy. People who have a history of skin cancer or eye disease should speak with their doctor before using red light therapy.
With lower power LED devices (e.g. 10mW/cm2) 30 minute sessions twice a day may be needed and may still not be enough for a good result. In any case, even 10 minutes of even low intensity LED treatment are better than nothing. However, for optimum and/or fast results, relatively higher light intensities will be needed.
You can put the items below on your skin before red light therapy: Start with a gentle cleanser to remove any dirt, oil, or makeup. Apply a light, hydrating moisturizer to keep your skin hydrated. Use a serum with antioxidants like Vitamin C to enhance the therapy's benefits.
The most beneficial red light wavelength for skin is commonly considered to be 660 nm, which is near the upper range of visible red light. This wavelength has deeper penetration than the shorter 630 nm wavelength, with similar effects.
Red light is the most sleep friendly light. It has a higher wavelength of light than blue, white or green and doesn't inhibit sleep or interfere with melatonin production. Red light doesn't improve sleep, it just doesn't interfere with the building blocks of it.
"[Red light therapy can] stimulate collagen production, reduce inflammation, and increase blood circulation, so it is primarily used for [fine lines and wrinkles] and wound healing," Sejal Shah, MD, a board-certified dermatologist based in New York City, previously told Allure.
Red light is a popular treatment for skin concerns, especially signs of aging like wrinkles, age spots, and sagging skin. People are also using it to treat hair loss. Whether you want to treat your skin or regrow hair, you'll find plenty of red-light devices sold for at-home use.
It delivers a very specific wavelength of red light that interacts with cells. Research has found that this particular color of light increases our cells' energy, opens the blood and lymphatic vessels to improve blood and lymphatic flow, and improves the healing rates of wounds.
“They aren't a game changer when it comes to fine lines, wrinkles, hair loss, etc.” Still, red light therapy definitely shows promise in the field of dermatology, especially due to its safe, noninvasive nature and its minimal side effects.
The recommended frequency of use for red light therapy will vary depending on the condition being treated, but most people will see benefits with 2-3 sessions per week.
Yes. If you are struggling with a sparse or patchy beard, red light therapy may help. This is especially true if you have an autoimmune condition like alopecia barbae. However, your ability to grow a full beard depends on many factors.
There is a low risk of side effects from undergoing RLT. However, prolonged or high-intensity exposure outside of treatment guidelines may damage the skin. Products for use at home may also lead to misuse, causing burns, blisters or damage to unprotected eyes.
The Dermatoscope: Your Dermatologist's Small Hand-Held Light
You might be wondering what your doctor is doing with this special light and the answer is that he or she is using it to perform “epiluminescence microscopy” (ELM) exam also known as dermoscopy (or dermatoscopy).
Bodemer recommends the Lightstim brand if you're looking for FDA-cleared light therapy wands. This wand has various wavelengths of red LED light that treat fine lines and wrinkles — the brand also has wands of different light wavelengths for pain relief and acne treatment.
