Research & Benefits of LED Light Therapy Treatment


  • LED, or light emitting diode therapy, is a skincare treatment that uses varying wavelengths of light, including red and blue.
  • NASA originally developed it for plant growth experiments on shuttle missions and later found it to have promise for wound treatment. LED light therapy is now used by some aestheticians to help regenerate the skin.
  • The three main treatments are red, yellow & blue light frequencies based on the skincare concern. Red is primarily used for anti-aging, yellow is used to repair sun damage & pigmentation and blue is used for acne treatment.


  • 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 is safe for all skin colours 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.


  • Clinic procedures can take up to 20 minutes a session plus you will need to travel to and from the clinic for treatment. You’ll need to go back twice a week for up to 10 weeks, then only once every few months.
  • At-home LED devices can be used at your convenience without having to go to any appointments for a much smaller one off cost than doing in salon treatments.


  • A single LED light therapy session ranges from about $55 to $85, depending on the area of the country and whether you’re combining it with other treatments. For a full 10 week treatment twice a week it can cost upwards of $1500
  • Our at home device will cost you much less time and money at only $226RRP.


  • When used as directed, LED light therapy can improve your skin within weeks. You’ll need maintenance treatments 2-3 times per week to maintain your results.

How it works

LED light therapy has an established history of skin uses. The U.S. Navy SEALs began using it in the 1990s to help heal wounds quickly and to help regenerate damaged muscle tissues.

Since then, the treatment has been researched for different situations in aesthetics. It’s mainly noted for increasing collagen and tissues. All of which can smooth out your skin and reduce the appearance of damage from:

  • age spots
  • acne
  • wrinkles
  • Sun damage
  • Pigmentation

There are different frequencies, or wavelengths, used with LED light treatment. These include red (622-627NM), yellow (580-583NM) and blue light (467-473NM) frequencies, which do not contain ultraviolet rays and are readily absorbed into the skin.

Red Light

Red 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 will reduce the appearance of fine lines and wrinkles. Red LED light is also known to reduce inflammation while improving circulation, which can give you a healthier glow.

Yellow Light

Yellow Light Therapy triggers the lymphatic system, improving the removal of toxins from the treated area.

Yellow Light Therapy is used to increase wound healing, collagen induction, skin hydration and the overall health of the skin.

This treatment is great for reducing the appearance of fine lines and wrinkles, improving uneven skin tone, reducing pores size, and brightening the skin. It can also assist with:

  • Rosacea & Redness of the skin
  • Dryness – Yellow LED Light Therapy increases the skin’s ability to hold hyaluronic acid and water. In turn this increases the skin’s hydration and makes your at home skincare go further. Basically, it helps to amplify your current skincare.

Blue Light

Blue LED Light Therapy 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 Blue LED light therapy targets these oil glands and make them less active. 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

Risks and side effects

The Therapeutic goods association deems this procedure safe. Since LEDs don’t contain UV rays, this is considered a safer form of light therapy that won’t cause long-term damage to your skin. The procedure is also noninvasive and has few risks.

Unlike more invasive procedures such as laser therapy, LEDs don’t burn your skin. They also don’t cause any pain.

However, there may still be risks associated with LED light therapy.

If you currently use Accutane for acne, be advised that this powerful drug derived from vitamin A increases your skin’s sensitivity to light and may cause scarring in some instances.

Do not use LED light therapy if you’re using anything on your skin that makes you sensitive to sunlight.

You also might consider avoiding this treatment if you currently have an active rash. 

Side effects from LED light therapy are rare and were not noted during clinical trials. Call your doctor if you experience any of the following symptoms post-treatment:

  • increased inflammation
  • redness
  • rash
  • pain
  • tenderness
  • hives

What to expect after therapy

LED light therapy is noninvasive, so no recovery time is required. You should be able to continue with your everyday activities once your treatment is over.

You will start to see results after your first session. Results will be more dramatic and noticeable once you’ve finished all of your treatments.

Even after you’ve achieved the recommended number of sessions, your results aren’t permanent.

As your skin cells turn over, you may lose some collagen and start to see signs of aging again. You may also start to see acne breakouts. This is why it’s recommended that you go back for maintenance treatments every few months or as recommended by your provider.
