In recent years, light-based therapies have gained popularity in skincare for their non-invasive approach to treating a variety of skin concerns. Among these, green light therapy has emerged as an effective and gentle treatment option, particularly for pigmentation issues, skin redness, and calming inflammation. We explore the science behind green light therapy, the technology that powers it, its proven benefits, and how you can seamlessly integrate it into your skincare routine.
What is Green Light Therapy?
Green light therapy is a form of low-level light therapy (LLLT), also reffered to as phototherapy, which uses specific wavelengths of light to penetrate the skin and produce therapeutic effects. Green light falls between 495 to 570 nanometers on the visible light spectrum, a range specifically chosen for its ability to target skin issues like hyperpigmentation and redness.
Unlike ultraviolet (UV) light, which can be harmful to the skin, green light therapy is safe, gentle, and free from damaging side effects. It works by soothing the skin, reducing redness, and breaking down excess melanin, the pigment responsible for dark spots.
The Science Behind Green Light Therapy
Green light works by penetrating the upper layers of the skin, targeting melanocytes (the cells that produce melanin) and inhibiting the production of excess pigment. This process makes green light particularly effective for treating conditions like mild hyperpigmentation, which is caused by overactive melanin production. By inhibiting melanogenesis, green light helps reduce the appearance of dark spots and evens out skin tone.
Additionally, green light has a calming effect on the skin, making it suitable for people with sensitive skin or rosacea. It reduces redness by dilating blood vessels and improving circulation, which in turn soothes inflamed or irritated skin.
According to a study published in the journal Lasers in Medical Science, light therapies, including green light, have been shown to successfully reduce melanin production and treat pigmentation disorders. The study further supports that phototherapy is a non-invasive, safe, and effective approach to managing pigmentation, inflammation, and skin irritation .
Proven Benefits of Green Light Therapy
1. Reduces Hyperpigmentation and Dark Spots
One of the primary benefits of green light therapy is its ability to fade dark spots and treat uneven skin tone caused by sun exposure, aging, or hormonal fluctuations. By targeting melanin overproduction at the source, green light gradually breaks down hyperpigmentation, resulting in clearer, brighter skin over time.
Research suggests that using green light for 10 to 15 minutes daily can significantly improve skin tone after several weeks of consistent use .
2. Calms Redness and Irritation
For people struggling with redness, rosacea, or general skin irritation, green light therapy is an ideal solution. The calming properties of green light help reduce blood vessel dilation, decreasing visible redness and inflammation. We would always suggest using red light first for Rosacea and green as a maintenance.
A study published in the Journal of Clinical and Aesthetic Dermatology showed that individuals with rosacea experienced reduced redness and skin sensitivity after incorporating light therapy into their skincare routines .
3. Improves Skin Clarity and Texture
In addition to treating pigmentation and redness, green light therapy can improve overall skin clarity and texture by promoting cell renewal. This therapy stimulates the production of collagen and elastin, two essential proteins responsible for skin firmness and smoothness. As a result, it not only helps improve the appearance of discolouration but also leaves the skin looking more even and youthful.
4. Non-Invasive and Pain-Free
Unlike other pigmentation treatments such as chemical peels or laser therapy, green light therapy is completely non-invasive. There’s no downtime or discomfort, making it an appealing option for people who want results without the risks associated with harsher treatments.
How Does the Technology Work?
Green light therapy typically comes in the form of LED (Light Emitting Diode) devices. LED devices emit specific wavelengths of light that penetrate the skin at varying depths, depending on the colour of light being used. Green light, as previously mentioned, targets the superficial to mid layers of the skin, making it perfect for treating pigmentation issues that lie closer to the surface.
Many at-home LED devices are designed for ease of use, and professional-grade devices are also available for those who prefer more powerful options. The key to effective treatment is using a device that provides the correct wavelength of green light to target specific skin concerns. Devices with a wavelength of 520-525 nanometers are often considered the most effective for pigmentation and redness concerns .

How to Integrate Green Light Therapy Into Your Skincare Routine
The best way to incorporate green light therapy into your skincare routine is to start slowly, allowing your skin to adjust to the new treatment. Here’s a step-by-step guide on how to get started:
1. Cleanse Your Skin
Start with a clean face to ensure that the light can penetrate your skin without obstruction. Use a gentle cleanser suited to your skin type.
2. Apply Green Light Therapy
Use your green light therapy device as instructed, typically for 10 to 20 minutes per session. Be sure to cover all areas of concern, such as dark spots or areas of redness. Start with 3-4 sessions per week and gradually decrease the frequency into a maintenance programme.
3. Apply Serums or Moisturisers
After treatment, apply a targeted serum, like our Pigment Clear, to further help with dark marks. Green light therapy boosts the skin’s absorption of topical products, so this is the perfect time to apply serums targeting pigmentation or redness. We suggest applying this serum ass nighttime only.
4. Don’t Forget Sunscreen
Sun protection is crucial when treating pigmentation issues. It’s important to protect your skin from further UV damage by applying a broad-spectrum sunscreen with SPF 30 or higher daily
Who Can Benefit from Green Light Therapy?
Green light therapy is particularly effective for individuals dealing with:
- Mild Hyperpigmentation
- Age spots
- Redness
- General skin irritation
- Uneven skin tone and texture
It is suitable for all skin types, including sensitive skin, and can be used by those looking for a gentle, non-invasive way to improve their skin’s appearance without the risk of irritation.
Backed by research and years of technological advancements, green light therapy is an excellent addition to both professional treatments and at-home skincare routines.
