The Radiant Glow: Unveiling the Power of LED Light Therapy for Skin

By Maren Stratte, Elizabeth G Stratte MD, and Andrew Copeland MD

In the ever-evolving world of skincare, new technologies and treatments continuously emerge to help us achieve healthier, more vibrant skin. One such advancement gaining popularity is LED light therapy. With its non-invasive nature and promising results, LED light therapy has become a sought-after treatment for a wide range of skin concerns. In this blog post, we will explore the fascinating world of LED light therapy and delve into its remarkable benefits for the skin.

Understanding LED Light Therapy: 

LED, which stands for Light-Emitting Diode, is a form of phototherapy that utilizes specific wavelengths of light to stimulate various cellular processes in the skin. The therapy works by emitting low-level light energy, which penetrates the skin's layers, triggering beneficial reactions at a cellular level. A common misconception is that the LED light mimics UV light, this is not the case, and LED light therapy is safe for most skin types.

Different wavelengths of light have different effects on the skin. Red light, typically ranging from 620 to 700 nanometers, is known for its ability to stimulate collagen production and improve overall skin tone and texture. Blue light, ranging from 405 to 420 nanometers, is renowned for its antibacterial properties, making it highly effective in combating acne and breakouts. Other colors, such as green, yellow, and infrared, also offer unique benefits when used in LED light therapy.

Benefits of LED Light Therapy for the Skin:

Stimulates Collagen Production: Red light therapy promotes the production of collagen, a vital protein responsible for maintaining skin elasticity and reducing the appearance of fine lines and wrinkles. By increasing collagen production, LED light therapy helps to improve skin firmness and reduce signs of aging.

Acne Treatment: Blue light therapy is a popular choice for acne-prone skin. Its antibacterial properties target the bacteria responsible for causing acne, helping to reduce inflammation and breakouts. Additionally, blue light therapy can regulate sebum production, minimizing oiliness and preventing future acne flare-ups.

Calms Inflammation and Redness: LED light therapy can soothe and calm the skin, making it an effective treatment for conditions like rosacea and skin sensitivity. By reducing inflammation, it can alleviate redness and promote a more even skin tone.

Enhances Healing and Recovery: LED light therapy stimulates circulation and accelerates the skin's natural healing process. This makes it an excellent post-treatment option for procedures like chemical peels, microdermabrasion, or laser treatments, as it can help reduce downtime and enhance the overall results.

Improves Skin Texture and Complexion: By boosting cellular activity, LED light therapy improves skin texture, leaving it smoother and more refined. It also aids in minimizing pore size and reducing hyperpigmentation, resulting in a more even and youthful complexion.

Non-Invasive and Safe: One of the significant advantages of LED light therapy is its non-invasive nature. Unlike some other treatments, LED light therapy does not cause pain, downtime, or adverse side effects. It is suitable for all skin types and can be used as a standalone treatment or in combination with other skincare procedures.

Professional VS. At-Home Treatments

There are pros and cons to both! Professional devices, which only estheticians and doctors have access to, penetrate deeper intro the skin, and are more controlled to create better, longer lasting results. However, best results come from consistent treatments, and for some individuals an at-home device will allow for that consistent usage.

Before you run out and buy your own at-home LED device, we encourage you to consider the adage, “you get what you pay for.” Counterfeit devices are routinely seen in circulation today where instead of using the actual colored bulb, companies will paint the bulb red, and call it red LED. It is difficult to often spot these devices which in turn can lead to a large waste of time and money.

 We recommend an 8 week regimen of one to three 20 minute professional sessions per week for best results. Or if this is not a doable addition to your skincare regimen, add it on to any esthetician service when you’re already in office! The benefits of reduced inflammation and breakouts can be seen in as little as one treatment. 


LED light therapy has revolutionized the skincare industry, offering a safe and effective solution for a wide range of skin concerns. From stimulating collagen production to treating acne and calming inflammation, the various wavelengths of light used in LED therapy provide targeted benefits for different skin needs. With its non-invasive nature and remarkable results, LED light therapy has become a go-to treatment for individuals seeking healthier, more radiant skin.

However, it's important to note that while LED light therapy can be highly beneficial, it should be performed by a trained professional or under their guidance. Consulting with a dermatologist or skincare specialist will ensure that the treatment is tailored to your specific needs and that you achieve the best possible results. So, go ahead, bask in the gentle glow of LED light therapy, and unlock the secrets to a luminous complexion.
