LED therapy, also known as low-level light/laser therapy (LLLT) or Photobiomodulation (PBM), is a non-thermal treatment that uses visible and near-infrared light to stimulate intracellular processes in the body. Yellow light is found between 565 and 590nm in the visible light spectrum and has a frequency of 510-530 THz. A Holonyak graduate student invented Yellow LED lights in 1972, its therapeutic effects were discovered later. Yellow LED light safely and painlessly penetrates the skin at a shallow range of 0.5mm and 2mm, shorter than red light, which has similar benefits. I will explain the benefits of yellow LED lights in this article.
Discovery of therapeutic effects of light
We can thank The National Aeronautics and Space Administration, NASA, for discovering light therapy and many other things. They tested different wavelengths of light for plant growth under challenging conditions and discovered that some lights enable plants’ growth in space. Every cell in our body has a mitochondrion which stores energy in the form of adenosine triphosphate (ATP) to fuel the cells’ energy to rejuvenate and heal. NASA also found that (Red Light) 633nm, (Green Light) 532nm, and (Blue Light) 415nm increases the body’s light sensitivity and ATP production.
Skin conditions yellow LED light therapy benefits
Skin texture improvement
Yellow LED light therapy enhances the skin’s structure by increasing collagen production, a protein and connective tissue that keeps our skin firm and youthful. It also improves elasticity, texture and overall cell regeneration. It reduces fine lines, wrinkles, and the size of pores. It’s excellent for skin rejuvenation.
Hydration and enhanced wound healing
Yellow LED light therapy benefits dry skin by making it soft and supple and boosting its hydration. It stimulates nutrient-rich blood vessel production, accelerating the body’s natural wound-healing processes. Surgical incisions, injuries, and aggressive treatments heal faster, and the skin glows due to enhanced cell renewal.
Corrects and balances skin tone
Yellow light therapy reduces sunburns or inflammation, heals UV radiation damage, and lightens dark spots for a more uniform skin tone. It increases blood flow in the skin dermis, which helps eliminate redness and rosacea.
Helps with pigmentation
Yellow LED light therapy benefits all skin tones. Darker skin tones benefit the most because it reduces the appearance of hyperpigmentation issues, such as sun spots, age spots, and melasma. Yellow lights’ anti-inflammatory and antioxidant properties help decrease pigment production. They also enhance cell turnover by shedding old, pigmented skin cells, allowing newer, brighter skin cells to rise to the surface.
Lymphatic drainage
Yellow LED light penetrates the skin’s shallow level and promotes lymphatic drainage to improve the removal of toxins, puffiness and bloating from the treated area. Yellow light therapy makes the skin appear healthier despite not increasing its health.
Acne treatment
Yellow LED light therapy enhances cell function, promotes faster healing and tissue regeneration, and effectively targets the bacteria that cause acne. Its anti-inflammatory actions reduce redness and swelling seen with acne and wound healing.
Improves mood
Yellow light increases serotonin production, enhancing Seasonal Affective Disorder (SAD) and promoting feelings of warmth and comfort.
Sleep regulation
Yellow light therapy can help regulate sleep patterns by producing melatonin, improving sleep quality and daytime alertness. Its warm glow also aids stress relief and relaxation, making it ideal for use after dusk.
Comparison of yellow LED and IPL and laser light
In my holistic aesthetics/medical spa, I use 580 nm of yellow IPL Intense Pulse Light for skin rejuvenation. It alleviates sun spots and superficial veins by 50% and improves collagen production by 100%. IPL is a broadband light condensed with a reflective material that gives the same results as a laser with less pain and shorter recovery time. Each handpiece of my IPL device sends out a specific wavelength of pulsating light. Specific skin issues may respond better to IPL or laser. IPL treats a range of skin conditions at the same time. However, unlike the Yellow LED light, it does not remove age spots.
Since Laser treatments are more intense, recovery time is longer. The results are more noticeable with fewer sessions. Isolation from the sun is necessary to avoid sun damage recurrence. Dermatologists offer medical-grade IPL or Laser light therapy, which has higher settings. A trained professional performs a medical history to determine when someone qualifies for IPL and Laser light therapy.
Additional considerations
Temporary side effects: Some individuals may experience temporary redness, stinging, burning, light sensitivity, or rash.
Eye safety: Light-blocking eye goggles should be worn during LED therapy to avoid potential eye damage, especially for those with eye problems or on photosensitive medications.
Photosensitive products: Certain medications and foods can increase light sensitivity, including antibiotics, antidepressants, and acne treatments with retinoids. Avoid using LED therapy light masks at home while taking these medications.

Conclusion
Yellow LED light therapy is a convenient way to improve the appearance of your skin. It safely reduces inflammation and dark spots. Because it possesses soothing effects, yellow LED light therapy is also suitable for surface-level skin concerns like redness and rosacea. However, it is more favourable for patients with darker pigmentation.
Traditional Chinese Medicine uses Yellow Light Therapy to address health concerns. Their culture believes different colours heal different body areas.
