What is LED Therapy?

Light Emitting Diode therapy, commonly called LED Therapy, is a non-invasive skincare treatment that uses specific wavelengths of light to address various skin concerns. It’s also known as phototherapy or light therapy.

The treatment involves exposing the skin to LED lights that emit different light colours, each with specific properties and benefits for your skin. Light therapy is often used to improve skin texture, reduce signs of ageing, and address issues such as acne, inflammation, and pigmentation. It can even be a good solution for hair restoration.

The LED light energy stimulates cellular activity by absorbing light into skin cells and triggering various cellular processes. For example, red light promotes the production of collagen and elastin, which are essential for skin firmness and elasticity.

How is LED Therapy performed?

After a detailed consultation ensuring the treatment will be suitable, the LED light is applied over the area of desired skin rejuvenation, whilst you are laying down. There is no pain, or redness after the treatment. All skin types can benefit from the treatment. The lights may feel a bit bright; if this is the case blackout goggles will be provided. 

How long does the treatment take?

The treatment will take approximately 20-30 minutes. Depending on the condition being addressed, patients will be advised in advance how many sessions they may need. We often combine the Light Emitting Diode therapy with other treatments such as Microneedling, or the HarmonyCA filler/biostimulator.

What skin issues can LED Therapy treat?

You will be pleased to know that LED therapy has been extensively researched and there are thousands of peer-reviewed and published research papers confirming it’s advantages.

One of the reasons that this treatment has gained popularity is for its potential benefits in addressing a variety of skin concerns. The effectiveness of LED therapy can vary based on the specific issue being treated, the wavelengths of light used, the individual’s skin type, and the quality of the equipment used. 

Here’s an overview of what skin issues can be addressed and their level of effectiveness:


LED therapy, mainly blue light (around 415 nm), has shown effectiveness in treating acne. Blue light has antimicrobial properties that target and reduce the population of acne-causing bacteria. Several studies suggest that blue light therapy can effectively manage mild to moderate acne.

Skin Rejuvenation

Red and near-infrared (NIR) wavelengths are commonly used for skin rejuvenation. Red light (around 630-700 nm) stimulates collagen production and promotes overall skin health. NIR light (around 800-900 nm) can penetrate deeper into the skin, potentially aiding in reducing the appearance of fine lines and wrinkles.

Wound Healing

Using especially red and NIR wavelengths, has been explored for its potential in enhancing wound healing. By stimulating cellular activity and promoting circulation, this treatment can help accelerate the healing process.


Some studies suggest that LED therapy, in combination with other treatments, could help manage hyperpigmentation by promoting more even skin tone. However, results can vary, and the effectiveness might depend on the individual’s skin type and the specific type of pigmentation being treated.

Inflammation & Redness

LED therapy, particularly red light, has been used to reduce inflammation and redness in the skin. It might be useful for calming the skin after certain cosmetic procedures like microneedling or chemical peels.

Is LED Therapy painful?

You will be pleased to know that this treatment is completely painless.

LED Therapy is a non-invasive skincare treatment that involves exposing the skin to specific wavelengths of light to address various skin concerns. The technology used during treatment is non-thermal, meaning it doesn’t produce significant heat like some other light-based treatments. This makes it comfortable and safe for the skin. 

Here are a few reasons why LED therapy is not painful:

  • Non-invasive treatment
  • No heat generation – no sensation of burning or discomfort
  • Mild sensation of warmth
  • Relaxing experience in a comfortable setting
  • No downtime following treatment

How does LED Therapy support Microneedling?

When combined with Microneedling, Light Emitting Diode therapy can enhance the overall effectiveness and recovery of your procedure. LED therapy supports Microneedling in the following ways:

  •  Reduces inflammation & redness
  •  Enhanced collagen production
  • Customised treatment
  • Long term results

It’s important to note that the effectiveness of Microneedling and LED therapy can vary from person to person. Results are often dependant on factors such as the individual’s skin type, specific concerns being addressed, and the expertise of your practitioner. Before undergoing any combined treatment, we recommended that you consult with a qualified dermatologist or skincare professional to determine the right solution for your skin needs.
