What Exactly is Light Therapy?

Light therapy, commonly referred to as phototherapy or heliotherapy, uses the inherent power of light to improve the health of your skin without the use of the hazardous chemicals that are present in many over-the-counter and prescription skincare products. The best part is that with personal light therapy products from QuasarMD, anyone can experience the amazing benefits of light therapy from their own home.

Light therapy (including blue light therapy and red light therapy) is often associated with skin conditions such as dermatitis, psoriasis, eczema, or acne. However, the benefits of light therapy extend beyond dermatological conditions and the practice is now commonly used for improving overall skin health and complexion. Light therapy can be used for anti-aging, to help eliminate wrinkles, heal skin, and reduce pain. The most beneficial light therapy products, such as QuasarMD products, reject harmful UV rays and instead employ LED lights.

Why use LED lights instead of UVs? The switch from using UV rays (which can have adverse side effects) to LEDs, or Light-Emitting Diodes, was advanced when NASA discovered that LED lights could speed the healing of certain wounds in space, vastly improving medical care for their astronauts. Removing the UV lights from light therapy products has allowed light therapy to be virtually free of side effects.

Two Types of Light Therapy and How They Work

There are two types of light therapy used for skin health - red and blue light therapy. Each method of light therapy has its own unique benefits and selecting which light therapy to use will depend on your skincare needs - with two common needs being anti-aging or anti-acne.  QuasarMD has a wide catalog of red light therapy products to suit your needs. Our products come in various colors and sizes so you are sure to find something to fit your budget.

Red Light Therapy

Red light therapy utilizes four separate wavelengths of light - amber, red, super red, and infrared. These four wavelengths each have their own benefits, and when they are distributed from a light therapy device to different areas of the skin, they are able to penetrate deeper than visible light. Red light therapy uses these specific wavelengths of red lights to enhance the functioning of the mitochondria, thereby improving cellular respiration and in turn, cell function. Improved cell function and reduced inflammation result in clearer, healthier skin. Red light therapy is generally selected over blue light therapy when the goal is to improve the health, look, and feel of skin, and harmful bacteria is not present. The benefits of using red light therapy are plentiful!

Blue Light Therapy

Blue light therapy is widely considered a non-invasive treatment for acne and other skin conditions such as sun damage and skin cancer. Blue light therapy works by using light that falls in the blue wavelength range to target and kill certain bacterias that live on the skin and beneath the skin's surface within follicles and pores. One common bacteria targeted by blue light is Propionibacterium acnes, a bacteria that is commonly found on acne-prone skin. If the bacteria can be eliminated, then the skin can heal and blemishes will be reduced. Many people use a combination of blue light and red light therapy.


  • Treats inflammatory acne and bacterial skin conditions
