What is LED Therapy?

What is LED Therapy?

LED, or light emitting diode therapy, is a skincare treatment that uses varying wavelengths of light. It was originally developed by NASA for plant growth experiments on shuttle missions and later found it to have promise for wound treatment. Since then the technology has been adopted by the beauty industry to help regenerate the skin from aging. It’s also used  to treat acne and hyper-pigmentation. The different light frequencies provide different benefits.  Red is used for anti-aging, blue is used for acne treatment and green is used for hyper-pigmentation.

Red light

Red, or infrared light is used for treating the epidermis, which is the outer layer of skin. When the light is applied to your skin, the epidermis absorbs it and then stimulates collagen proteins.

More collagen means that your skin will look smoother and fuller, which can reduce the appearance of fine lines and wrinkles. Red LED light is also thought to reduce inflammation while improving circulation, which can give you a healthier glow.

Blue light

Blue LED light therapy, on the other hand, targets the sebaceous glands, which are also called oil glands. They’re located beneath your hair follicles.

Sebaceous glands are necessary for lubricating your skin and hair so that it doesn’t dry out. However, these glands can become overactive, leading to oily skin and acne.

The theory is that blue LED light therapy can target these oil glands and make them less active. In turn, you may see fewer acne breakouts. Blue light can also kill acne-causing bacteria beneath the skin, which can help treat severe acne pimples, including cysts and nodules.

Oftentimes, blue LED light is used in conjunction with red LED light to:

  • help treat acne
  • decrease scarring
  • promote anti-inflammatory effects

One 2018 animal study Trusted Source found that blue LED improved healing of third-degree skin burns.

Unlike other types of light therapy, LEDs do not contain ultraviolet rays. Therefore, they’re safe for regular use.  LED light therapy doesn’t cause burns compared to other anti-aging treatments such as chemical peels, dermabrasion, and laser therapy. It may be safe for all skin colors and types. You shouldn’t use LED light therapy if you take Accutane for acne or if you’re experiencing skin rashes. Side effects are rare, but may include increased inflammation, redness, and rashes.

LED therapy facials can be provided by a professional licensed esthetician or you can use an at home device like our Anti-Wrinkle Wand to perform the treatment from the comfort of home. The treatment should be performed for 10 up to 20 minutes at a time. It is safe for daily use.

When used as directed, LED light therapy can improve your skin over time. 
LED therapy is also safe for all skin colors, and it doesn’t cause any burning. You’ll need maintenance treatments to maintain your results.


Talk to your dermatologist about your skincare concerns and whether LED light therapy is a good option for you.
