LED technology is no longer reserved for dermatology clinics. Now available for home use, it's proving a true beauty ally for the skin... and also for the scalp. At Myssera, we integrate this technology into a holistic approach to hair care. Red, blue, or infrared light: what are the differences? What are the benefits? And most importantly, is it really effective? A closer look.
How does photobiomodulation work?
Photobiomodulation relies on the use of different wavelengths of light (LEDs) to stimulate cells. These lights, depending on their color, penetrate to different depths of the skin or scalp and trigger specific biological reactions: cell regeneration, reduction of inflammation, stimulation of collagen production, or even elimination of bacteria.
Red light (633 nm): the ultimate anti-aging weapon
Red light penetrates deep into the skin. It activates fibroblasts, the cells responsible for producing collagen and elastin. The result: firmer, smoother skin that's better protected against the signs of aging. It's also used to improve microcirculation and accelerate healing.
In the scalp, this light stimulates blood circulation around the follicles, thus supporting hair growth, reducing hair loss and revitalizing tired areas.
Blue light (415 nm): a purifying ally against imperfections
Blue light works more on the surface. It specifically targets acne-causing bacteria, including Cutibacterium acnes. It helps reduce breakouts and inflammation, and regulate sebum production.
Applied to the scalp, this light is particularly useful for oily or dandruff-prone skin, soothing itching and purifying the roots.
Infrared light (830 nm): deep cellular regeneration
Less well-known to the general public, infrared light is invisible to the naked eye. It penetrates even deeper than red light and acts directly on tissue regeneration. It is ideal for promoting healing, calming persistent inflammation, and restarting cellular functions.
Combined with red light, it strengthens its effects and helps maintain a healthy environment for the skin and scalp.
Solid clinical studies to support this
Numerous scientific publications validate the benefits of LEDs on the skin. A study published in the Journal of Photochemistry and Photobiology demonstrated that regular use of red and infrared LEDs significantly improves skin texture, reduces wrinkle depth, and accelerates healing.
Other studies show a slowing down of hair loss and a visible thickening of the hair after several weeks of treatment combining red light and massage.
A beauty ritual accessible from home
Home LED devices, such as those incorporating Myssera technology, allow these benefits to be replicated safely at home. Treatments are simple, painless, and require no downtime.
Recommended duration: 8 to 10 minutes per session, 3 to 5 times per week, on clean, dry skin or scalp. Results are generally visible after
