In aesthetic medicine, LED technology is called photobiomodulation. It uses precise wavelengths to stimulate cells without excessive heat, a process often compared to "photosynthesis" for the skin.
In general 4 colors / wave lenghts are used
Each color penetrates to a different depth to target specific problems:
Red (633 nm): The most commonly used for anti-aging. It stimulates fibroblasts to increase the production of collagen and elastin.
Blue (415 nm): Targets the superficial layers to destroy acne-causing bacteria and regulate sebum.
Yellow (590 nm): Improves blood and lymphatic circulation. It is ideal for reducing redness and draining edema.
Infrared (830 nm): Penetrates the deepest. It is preferred for post-operative healing and reducing inflammation.
Visible Transformations
The medical use of LEDs produces tangible changes over the course of the sessions:
Skin Quality: Skin texture is refined and pores become less visible.
Glow: An immediate improvement in tissue oxygenation restores radiance to dull complexions.
Wrinkle Reduction: Fine lines are diminished thanks to collagen remodeling (a 31% reduction in wrinkle volume has been observed in some studies).
Accelerated Healing: Highly effective for fading recent acne marks or reducing bruising after hyaluronic acid injections.
Soothing: A significant reduction in skin inflammation (rosacea, diffuse redness).
Why choose medical treatment over at-home care?
Although consumer-grade masks exist, devices used in clinics offer significantly higher power (irradiance). This allows for much faster, visible results (often in just 4 to 6 sessions).
