Red Light for your FACE. What Does the Science Say?

Red light therapy (RLT) is one of the few “wellness trends” that actually has a growing body of legitimate research behind it (especially for skin health and facial rejuvenation).

Red light therapy is a gentle, non-invasive treatment that uses specific wavelengths of red and near-infrared light to support the body’s natural healing processes. When this light is absorbed by the mitochondria it boosts cellular energy, which can help reduce inflammation, promote collagen production, speed up healing, improve circulation, and support hormonal balance and mood, and more. Red light therapy is generally considered very safe when used properly, even for kids or during pregnancy (though you should always consult your provider before starting).

Studies show that specific wavelengths of red and near-infrared light can stimulate fibroblasts (the cells responsible for making collagen and elastin), increase cellular energy production, improve circulation, and calm inflammation in the skin. Clinical trials have found improvements in fine lines, wrinkles, skin texture, elasticity, redness, healing, and overall skin appearance with consistent use.

Red light is amazing because it works WITH the body rather than damaging the skin to force repair (vs things like chemical peels, microneedling, etc.).

Unlike UV light, red light is non-ionizing and does not burn the skin. Instead, it supports mitochondrial function - basically helping skin cells produce more energy so they can repair and regenerate more efficiently.

Research also suggests it may help reduce inflammatory pathways, support wound healing, and improve skin barrier function, which is why so many people notice benefits not just in anti-aging, but also in acne, redness, post-inflammatory healing, and overall skin glow.

The biggest key in the research is consistency and device quality. Studies showing the best outcomes typically use clinically relevant wavelengths (commonly around 630–660nm red light and 830–850nm near-infrared light) multiple times per week over several weeks. While you won't see overnight results, the science absolutely supports red light therapy as a powerful, non-invasive tool for supporting healthier, more resilient skin overtime.

Fringe's Mask Recommendations:

"We recommend using once a day on any one mode for 10 minutes, 3-7 times/week. We don’t recommend using all 3 modes in one day or in one session."

What drew me to Fringe's mask was their EMF testing. They test 0.0mG at 0” (meaning they test RIGHT on the skin) !!!

A note on Blue Light - especially for acne prone skin

Some red light masks (like Fringe) will include a blue light mode, as well. Blue light in the 400nm wavelength range has natural antimicrobial properties, which is why it’s often used in treatments for acne and other skin concerns. This is commonly known as “blue light therapy.”

Certain compounds in the skin, called porphyrins, absorb blue light. These compounds are found around the oil glands where acne-causing bacteria tend to grow. When blue light interacts with them, it creates a reaction that helps destroy the bacteria - making blue light therapy especially helpful for inflammatory acne.
