What is LED?

LED stands for light emitting diode, which utilises light to create change in the skin. It is a pain free, non-invasive clinical treatment that can target various skin concerns. And want to know a cool fact? LED Light Therapy was actually created by NASA for astronauts in space to help them heal any wounds faster!

How does LED work?

LED causes a photochemical reaction in the skin that influences the cells to respond or behave in a certain way.
Depending on the skin concern that is being treated, depends on which colour of light will be used. Light is measured in wavelength. The wavelength determines the distance that that particular colour of light can penetrate.

If you look at a photo of the light spectrum, you will see that the nanometres give strength to the light. The higher the number the deeper the light is able to penetrate, the lower the light the more superficial that particular light is functioning.

Different coloured lights:

Blue Light
Works superficially on the skin, treating the epidermis. Blue light treats skin conditions like active acne, as the blue light kills off acne causing bacteria such as Propionbacterium Acnes and also reduces inflammation and irritation within the skin. 

Yellow Light
Is able to penetrate a little deeper. Working to stimulate lymphocyte production (white blood cells) and activate toxin elimination. Yellow light is suited to help skin conditions such as – rosacea, flushing, couperose etc.

Red Light
Is the deepest penetrating light. The red light has the ability to work within the dermal layer of the skin. The dermis is home to the fibroblast cell which is responsible for the production of our collagen and elastin proteins. These proteins help to repair and rebuild our skin tissue, making it great at treating texture and tone. 

Your skin therapist can also combine different LED lights together to target multiple cells at the same time. 

Popular Treatments To Pair With LED  

Ultrasound (Sonophoresis)
LED light therapy works very well as a pre-treatment to LED. With LED we are getting our cells active and ready to work, so the minute we start feeding our cells with products, they’re ready to use those nutrients effectively. 

Exfoliation Treatments (Microdermabrasion, Chemical Peel, Epiblading)
Either before or after. Doing an exfoliation before LED can intensify the light absorption. Or post chemical peel depending on the chemical formulation of that particular peel, this can help to calm the skin and excellerate downtime. 

Skin Needling (Collagen Induction Therapy)
By doing LED before CIT encourages the cells (white blood cells and fibroblasts) to become energised and prepare for the inflammation process in response to the skin needling. When LED is done post CIT, it has the potential to inhibit the inflammation process which could affect the upregulation of collagen and elastin. 

LED on its own
LED can be used as a stand alone treatment. This is great for skins that are very inflamed and for skins that may not be suitable for other treatments. It is amazing for teenagers who need to go to school the next day, the skin isn’t left red or unsettled. 

LED also helps the healing of bruises, open wounds and scarring. 


Does it hurt?
LED is non-invasive, no sensation is felt when you’re lying under the lamp. LED lights have amazing therapeutic benefits, you will feel incredibly relaxed after your session. You will also be wearing protective goggles during your LED session to block out the light. 

How often do I have to have an LED session to see results?
If a client is having LED alongside another treatment, it would be fine to have the LED at the time frames that they’re having those treatments because in this case, the LED would be working more like a booster to those subsequent treatments e.g., micro, chemical peel. If we are doing LED sessions on their own, we want to be consistent with the delivery of light to maintain cellular energy, so ideally we would have the client in for 2 sessions a week for 3-4 weeks. 

What are contraindications to LED?  

Cancer – Anyone who is undergoing cancer treatment is not suitable for LED treatments. The reason being is that LEDs are designed to energise cells, and we don’t want to be giving energy to any kind of cancerous cells. 

Epilepsy – Anyone who is affected by epilepsy is not suitable for having LED or at the minimum should obtain a doctors certificate of approval. The reason being is that flashing or contrasting lights can trigger seizures. 

Pregnancy – Although there has not been any recent studies to show that LED may affect your pregnancy in any way, it is down to personal preference and if the client is comfortable with going ahead with the treatment.
