Does LED Light Therapy Work? A Guide to LED Light Therapy for Skin

February 7, 2024

LED light therapy has emerged as a popular non-invasive skin treatment for various skin issues such as acne, sun damage, rosacea, eczema, and more. This therapy utilises light-emitting diodes (LEDs) with different wavelengths to trigger the skin’s natural healing processes, leading to remarkable results. In this blog, we’ll delve into the effectiveness, uses, who should not be using LED light therapy and the difference between at-home and in-clinic treatments.



What is LED Light Therapy?

LED or light emitting diode therapy is a popular pain free, non-invasive skin treatment that stimulates your skin’s natural healing process to repair the skin. The treatment uses varying wavelengths of light to trigger this response and is most commonly used in the treatment of acne, sun damage, wounds, ageing, dermatitis and eczema. LED has shown expectational results in wound healing, tissue growth and skin rejuvenation. The therapy employs different light wavelengths to penetrate the skin at various depths, stimulating biological processes that promote skin rejuvenation and healing. Only 3 of these wavelengths are clinically proven in studies and they are blue, red and near infrared.



How effective is LED Light Therapy?

Research suggests that LED light therapy is effective for wound healing and addressing various skin conditions including acne, skin ageing and inflammation. Studies also indicate positive outcomes for cosmetic procedures, with LED devices demonstrating effectiveness in treating psoriasis and mild-to-moderate acne. However, consistent sessions are required to observe noticeable improvements, and because LED treatments do not contain UV rays, it is considered safe for regular use. A course of LED treatments over 6-8 weeks will offer corrective and lasting results, although you should be able to see some difference after the first few weeks.

Benefits and Uses:

LED masks offer a range of benefits, making them suitable for treating multiple skin conditions such as acne, dermatitis, eczema, psoriasis, rosacea, scarring, signs of aging, sun damage, and other inflammatory skin conditions. If we look at the clinically proven wavelengths of blue, red and near-infrared we can see the role each wavelength plays.

Blue: Blue light is used to treat acne and does this by eliminating acne causing bacteria from the skin and reducing the amount of oil produced.

Red: Red light stimulates the skin cells called Fibroblasts which are responsible for making collagen.

Near-infrared: NIR increases blood flow and oxygenation which helps increase collagen and elastin production and reduce inflammation in the skin.



Who should NOT be using LED Light Therapy?

LED light therapy is not right for everyone! If you take certain medications that make you more photosensitive it is a no, if you have a history of skin cancer it is a no, if you are pregnant or breastfeeding it is not recommended, if you suffer from light-induced headaches it is also not recommended. For example if you are taking prescribed accutane for treatment of acne, you should not be using LED. It is always important to check contraindications before using any device.

What is the difference between at-home and in-clinic LED?

The main difference between at-home and in-clinic LED comes down to the strength, so whilst regular consistent use of your at-home device will definitely deliver results, the best course of action would be to have a mix of in-clinic treatments whilst also using your at-home mask regularly. So how do you know which at-home device to buy?

With so many at-home devices available on the market, is important that you choose the right device for you as not all LED therapy devices deliver the same results and in some cases they that do little more than shine light onto your skin. If you want to see results, it’s important that you are looking at the device’s specifications, quality and if it is TGA approved as purchasing the wrong one can be a waste of time and money so make sure you do your research!

Treatment and Results!

Consistency is the key when it comes to enjoying the benefits of at-home LED treatments and it’s best to follow the instructions that come with your device as to how many sessions per week. Most at-home LED devices will recommend regular use (3-4 times per week) for a certain amount of time to see results and then ongoing maintenance thereafter that is convenient for you. For in-clinic treatments it is normally recommended 2 sessions per week for 4 weeks, so visit your nearest skin clinic and start your in-clinic and at-home LED journey today!
