The Benefits of LED Light Therapy For Your Skin

What if I told you there is a light that’s good for your skin? As new technologies continue to shape the aesthetic industry, skincare has moved on from routine serums and creams to LED skin therapy for skin benefits that work on multiple wavelengths to make a noticeable difference in your skin. Keep reading to discover a range of LED mask benefits and identify your skincare goals.


What is LED skin therapy?

LED therapy (light-emitting diode) uses light at varying wavelengths and frequencies to address multiple skin concerns. When used over a few sessions, LED light therapy has shown promising results in the treatment of mild acne, rosacea, psoriasis, actinic keratosis, dermatitis, wound and scar healing, photoaging and photodamage. In the beauty industry, LED light therapy most commonly uses red, near-infrared or blue light to penetrate the skin at different depths, triggering anti-inflammatory and cellular repair processes.

Not to be confused with ultraviolet rays used in sunbeds and UV gel lamps, at home LED light therapy is a safe, non-thermal energy often used for reversing the signs of ageing caused by UV damage.

How does light therapy work?

Light therapy devices generate different wavelengths that, when reaching cells, cause them to react and quickly activate photo-biochemical processes. This activation is what helps to reduce inflammation, initiate wound and scar healing, prevent cellular damage and stimulate collagen production.

LED wavelengths are seen as varying colours of the visible light spectrum, targeting different layers of skin. Blue (400nm to 470nm) works on the upper layers of skin, ideal for eliminating acne-causing bacteria. Yellow (560nm to 590nm) targets the middle layers of skin, while red (620nm to 750nm) reaches the deeper layers to stimulate natural cell repair.


LED benefits


Blue light therapy benefits

Interacts with the cells up to 1mm on the skin’s surface, helping to initiate antioxidant activity for reducing inflammation for skin conditions such as acne, rosacea, psoriasis and eczema.

The CurrentBody Skin Anti-Blemish LED Face Mask uses both blue LED light, as well as red LED light, to treat mild to moderate forms of acne and even prevent breakouts. The blue light eliminates acne-causing bacteria, as well as regulating sebum production; two of the main causes of acne and blemishes.


The benefits of yellow light therapy

Also known as amber, this wavelength reaches up to 2mm below the skin’s surface to stimulate lymphatic drainage and blood circulation, removing toxins and improving the skin’s metabolic processes.

Yellow light therapy is best known and loved for its anti-inflammatory properties, reducing redness in the skin and smoothing the overall appearance for a flawless, airbrushed effect.

The CurrentBody Skin LED 4-in-1 Zone Facial Mapping Mask utilises yellow LED light to target areas in the face that require healing. Ideal for areas of redness that have been affected by acne, the yellow light wavelengths will penetrate deep into the skin and target the affected areas.


Red light therapy benefits

Proven to work on the skins ‘powerhouse’ layer up to 4cm below the skin’s surface, red wavelengths reach the mitochondria to produce more energy for natural collagen and elastin production, along with accelerated skin repair.

Red light therapy face masks stimulate the skin to produce ATP (adenosine triphosphate), powering the skin cells and stimulating the production of collagen.

The CurrentBody Skin LED Light Therapy Face Mask uses both red and near-infrared light to target the skin cells, enhancing blood circulation and calming redness to create an even skin tone.

The benefits of LED masks for acne

Blue light therapy for acne is the most common light therapy treatment for a skin condition found at the dermatologist's office. It has been shown to remarkably reduce the number and severity of acne lesions with just a few sessions of light therapy performed at fixed intervals. The antimicrobial effect of blue light eliminates breakout-causing bacteria in the pores and oil ducts, while reducing inflammation and redness.


The benefits of LED masks for wrinkles and fine lines

Red and near-infrared wavelengths penetrate the deeper layers of skin, stimulating the mitochondria to generate more energy for cell repair and skin rejuvenation. The increase in natural collagen and elastin production minimises fine lines and wrinkles, while keeping skin plump and supple.

Light therapy for eczema or dermatitis

Millions of people from all over the world suffer from eczema or dermatitis, with very little treatment available. People often think that red light therapy for eczema is the most effective treatment, but blue light therapy is also a proven solution.

A few minutes of blue light therapy per week can soothe itching and reduce flare-ups with anti-inflammatory action.


Light therapy for psoriasis

Both blue and red light therapy can improve the symptoms of psoriasis over several sessions by reducing inflammation and slowing the accumulation of skin cells. Though light therapy alone can’t cure psoriasis, it can be used to effectively limit the progression and alleviate symptoms when used consistently.


Healing wounds with light therapy

Red and near-infrared wavelengths can also be used to effectively accelerate the natural healing process for burns, ulcers, wounds and post-surgical scars by stimulating the mitochondria.

Light therapy reduces inflammation in the affected area, and stimulates collagen production, encouraging tissue formation over the wounds.

At home LED light therapy devices

LED light therapy is one of the top skin therapies of 2024, popularised in pop culture such as Netflix’s Emily in Paris; an ideal solution for those wanting a convenient way to achieve lasting, professional results from home.

Light therapy for skin has been used for decades in-clinic, whether in a dermatologist’s office to treat specific skin conditions or a beautician’s spa during a facial. Now, you can access this FDA cleared technology from the comfort of your own home with portable, clinic-grade home use devices:

Dermalux Flex MD is the world’s most powerful in-clinic LED light therapy treatment now available for home use. Large enough to treat both the face and body, this flexible device can be used flat or mounted on a stand to reach any area with ease.

360 LED bulbs deliver clinically proven blue (415nm), red (633nm) and near-infrared (830nm) wavelengths within 30 minutes—suitable for all ages, skin tones and types. The Dermalux Flex MD is ideal for targeting rosacea, eczema, psoriasis, mild acne, scarring and the visible signs of ageing. 

As for LED face masks, the original CurrentBody Skin LED Light Therapy Face Mask offers complete facial anti-ageing with red (633nm) and near-infrared (830nm) wavelengths. Designed to prevent and reverse the visible signs of ageing, this mask is ideal for reducing fine lines and wrinkles while giving skin a plumpness linked to ample collagen.

For those wanting more than just anti-ageing, the multi-wavelength mask includes green (532nm), yellow (590nm) and deep red (660nm) wavelengths, in addition to red and near-infrared. Our CurrentBody Skin LED 4-in-1 Zone Facial Mapping Mask uses 4 treatment modes to activate specific cells on a biological level to restore brightness, soothe facial redness, balance oil production and increase elasticity.

What makes this mask unique however, is the introduction of Zone Facial Mapping—an industry-first that links specific skin concerns with the corresponding wavelengths. This boosts the 10-minute session by targeting not just one concern, but a multitude within the same timeframe.


LED benefits for skin


Specific LED masks have also been created to exclusively target areas around the eyes, lips, neck, décolletage and hands. These medical-grade portable devices provide focused wavelengths specifically attuned to their treatment areas—ideal for plumping lips, fading dark undereye circles, fading neck créping and sun spots.

They’re designed to be layered together, almost like you would skincare, allowing you to customise sessions based on your skin goals.
