How Does Green Light Therapy Work?
Green light therapy works by targeting pigment-producing cells and inflammatory responses in the upper layers of the skin. Unlike red light, which reaches deeper into the dermis to boost collagen production, green light focuses on the epidermis, where it can help fade discoloration and calm irritation.
Key Benefits of Green Light Therapy:
- Reduces Hyperpigmentation – Targets melanin production to help fade dark spots and sun damage.
- Soothes Redness and Inflammation – Can help calm sensitive or reactive skin and reduce visible redness.
- May Support Wound Healing – While research is still developing, some experts suggest it could improve circulation and aid skin recovery.
Dr. Hadley King, another board-certified dermatologist featured in the article, added that green light might also have anti-inflammatory effects that support wound healing and improve skin’s overall radiance.
However, studies on green light therapy remain limited, and more research is needed to fully confirm its long-term benefits. Dr. Ellen Marmur cautioned that those with photosensitivity issues, certain eye conditions, or those who are pregnant should consult a doctor before trying green light therapy.
Dr. Kiran Mian’s Expert Advice on Choosing a Green Light Therapy Device
At-home green light therapy devices are becoming increasingly popular, but Dr. Kiran Mian advises caution when selecting one. Since LED therapy devices aren’t standardized, choosing a reputable brand with clear energy specifications is essential.
Her key recommendations when shopping for a device:
- Look for FDA-cleared devices – This ensures the device has been tested for safety and effectiveness.
- Check clinical data – Reliable brands will provide studies or test results to back up their claims.
- Be consistent with usage – Results take time, so following the manufacturer’s guidelines is crucial.
Best At-Home Green Light Therapy Devices
Some of the top FDA-cleared green light therapy devices featured in the article include:
- MMSkincare MMSphere Luxe – Offers nine light settings and requires three sessions per week for 20 minutes.
- Lumara Illuminate Green – A premium option requiring just five minutes per day; comes with protective goggles.
Dr. Mian emphasizes that while green light therapy can be a helpful addition to a skincare routine, it should be used alongside a well-rounded regimen, including sunscreen and brightening ingredients like vitamin C and niacinamide.
She also recommends wearing protective eyewear when using LED devices at home and stresses the importance of consistency—results won’t appear overnight but will progress gradually with regular use.
