1. What is LED Light Therapy?
LED (Light Emitting Diode) light therapy is a non-invasive treatment that uses varying wavelengths of light to target different skin and health conditions. Originally developed by NASA in the 1990s for plant growth in space, this technology was later found to have incredible benefits for human and animal health. Today, it is widely used in dermatology and wellness practices for skin rejuvenation, pain relief, and overall health improvement.
LED light therapy works by emitting light at specific wavelengths that penetrate the skin to different depths. Unlike ultraviolet (UV) light, which can damage skin cells, LED light is free of harmful radiation and is safe for regular use. Depending on the wavelength used, LED light therapy can serve various purposes:
- Red Light (630nm–660nm): Red light is one of the most studied wavelengths and is best known for its ability to boost collagen production, reduce inflammation, and promote healing. Red light penetrates the skin deeply, affecting the epidermis and dermis layers to stimulate fibroblasts, which are the cells responsible for collagen production. This makes red light therapy a popular choice for reducing fine lines, wrinkles, and scars, as well as for improving skin texture.
- Blue Light (415nm-495nm): Blue light therapy is effective for more than just acne treatment. While it targets the bacteria Propionibacterium acnes, which is responsible for acne breakouts, its benefits extend to several other skin conditions. Blue light has antibacterial properties and is effective at reducing inflammation, helping to calm and clear acne-prone skin. Additionally, it is beneficial for conditions like psoriasis and rosacea, where it helps to alleviate redness and inflammation. Moreover, blue light is increasingly used in mood therapy, particularly for Seasonal Affective Disorder (SAD), as it can improve mood and energy levels by mimicking natural sunlight.
- Green Light (520nm–550nm): Green light is known for its soothing properties and is often used to reduce redness and irritation. It’s also believed to improve skin tone and treat hyperpigmentation by targeting the melanocytes in the skin that produce excess melanin, and scientifically proven to reduce pain and frequency within headaches and physical conditions such as fibromyalgia.
- Near-Infrared Light (700nm–1000nm): Near-infrared light penetrates even deeper than red light, reaching muscles and tissues beneath the skin. This makes it effective for pain relief, reducing inflammation, and promoting healing in injuries.
The reason LED light therapy works for both humans and animals is that it impacts the cells at a molecular level. Cells absorb light in a process called photobiomodulation, which enhances the production of ATP (adenosine triphosphate), the molecule that provides energy to cells. This increased energy accelerates cellular repair, reduces inflammation, and promotes healing. Since cells in animals function similarly to human cells, LED light therapy has been successfully used in veterinary medicine for treating wounds, joint issues, and skin conditions in pets and larger animals.
LED light therapy has a variety of uses beyond skincare, such as treating chronic pain, arthritis, and even mood disorders like seasonal affective disorder (SAD). It is safe for all skin types, causes no downtime, and can be used in conjunction with other treatments. Whether for aesthetic or therapeutic purposes, LED light therapy offers a natural and scientifically supported way to improve both skin health and overall well-being.
2. Introduction to LED Light Therapy and Skincare
LED light therapy has become a popular and effective way to treat various skin conditions, from acne to signs of aging. By using different wavelengths, such as red, blue, or green light, this treatment stimulates the skin at a cellular level.
Red light (around 630nm-660nm) is known for boosting collagen and reducing inflammation, while blue light (415nm) targets acne-causing bacteria. For people using this therapy as part of their skincare routine, it’s important to choose the right ointments to complement and enhance the treatment. Some products can boost the results, while others can potentially interfere with the therapy.
3. Ointments to Use with LED Light Therapy
Choosing the right skincare products to use alongside LED light therapy can maximize its benefits. The following ointments are highly recommended for their synergistic properties with light therapy:
Hyaluronic Acid
Hyaluronic acid is a powerful humectant, meaning it helps your skin retain moisture. During and after LED light therapy, it keeps your skin hydrated, ensuring that light penetrates more effectively and stimulates skin rejuvenation.
Fact: Hyaluronic acid can hold up to 1,000 times its weight in water, making it an ideal product to keep skin plump and moist during therapy sessions.

4. Ointments to Avoid During LED Light Therapy
While some skincare products can enhance the effects of LED light therapy, others should be avoided to prevent skin irritation or interference with light absorption.
Retinol (Vitamin A)
Retinol promotes skin cell turnover, making it a popular anti-aging ingredient. However, it also increases photosensitivity, which can lead to irritation when used with light therapy. It’s best to avoid retinoids before LED sessions.
Fact: Retinol can increase the skin’s sensitivity to light, leading to potential redness or irritation if used before LED therapy.
