What You Need To Know About Blue LED Light Therapy

• 07 March 2024

LED light therapy is growing in popularity. It’s a proven treatment for a load of skin conditions without pain or needles. Naturally, people are becoming curious about blue LED lights and if they should invest in LED light therapy at home. To help, we’re answering some common questions about LED tech below.

What does LED stand for?

LED (light-emitting diodes) light therapy comes in a range of colours for different wavelengths. Blue light is made up of the shortest waves and carries the most energy. Everyone knows about the blue light that comes from their screens that can keep you awake at night, however, in specific, concentrated doses blue LED light can do wonders for your skin.

What is blue LED treatment?

Light therapy started out as NASA technology. Now it's used across a range of visible light spectrums to offer unique skin and pain relief benefits. Blue LED light treatment uses blue light emitting diodes to kill acne-causing bacteria on the skin.

Does blue light therapy really work?

Yes. In this clinical study, participants saw less acne, blackheads, whiteheads, inflammation and skin irritation following treatment. And they felt comfortable administering the treatment by themselves too. They reported no pain and the study concluded essentially that blue LED lights are effective against mild to moderate acne and skin concerns.

What is blue light therapy really good for?

It’s most effective against mild to moderate acne. Professional-grade devices like the CurrentBody Skin Anti-Blemish LED Face Maskare also effective for a larger range of concerns including fine lines and wrinkles, hyperpigmentation, redness, psoriasis and muscle or joint pain. That’s because it combines blue LED lights with red and near-infrared lights to maximise the light therapy benefits.

Can you do LED light therapy at home?

  • Near-infrared light therapy: Stimulates collagen production
  • Red light therapy: Reduces inflammation and redness
  • Blue light therapy: Eliminates acne-causing bacteria
  • Yellow light therapy: Relieves sensitive skin
  • Green light therapy: Evens out skin tone

  • Based on the benefits of each wavelength, you can choose the device best suited to your skin concerns.

    What is the best LED light therapy?

    The best blue LED light therapy device for treating mild to moderate acne on the face is our CurrentBody Skin Anti-Blemish LED Face Mask. It combines blue (415nm) light with anti-inflammatory red (633nm) light to effectively reduce redness, swelling and acne-causing bacteria. Together, these wavelengths are 36% more effective at treating acne than blue light alone.

    For the odd breakout, the CurrentBody Skin Anti-Blemish LED Pen provides quick spot reduction. Although it uses the same light therapy technology as the Anti-Blemish LED Face Mask, the pen is a smaller, more compact device. It’s perfect for reducing a breakout in 3 minutes, without drying out the skin or disrupting the skin barrier (or your schedule).
