Red Light Therapy and Skin Aging
Red light therapy is widely used in skincare routines. Research into photobiomodulation (PBM) investigates processes related to skin structure, collagen, and regeneration, among other things. However, this does not mean that every consumer device can demonstrate the same results.
What do we know about fine lines and elasticity?
Skin aging involves changes in collagen structure, elasticity, and the skin's ability to repair itself. Red and near-infrared light are being investigated for their potential influence on cellular processes. The quality of evidence varies depending on the application and study.
Why are wavelength and dose important?
A device is not just a color of light. Wavelength, irradiance, treatment time, distance, and the total dose together determine light exposure. Therefore, you cannot fairly compare two devices based solely on the number of LEDs or wattage.
What can you realistically expect?
Do not expect an immediate change after one session. When someone experiences improvement, a consistent routine is important. Results vary per person, skin condition, device, and usage protocol.
Conclusion
Anyone considering red light therapy for skincare would do well to look at the actual specifications and not just marketing terms. Kenza Beauty Lab therefore opts for transparent information about technology, wavelengths, and usage.
