Many dermatologists use a floor-stand device referred to as Light Emitting Diode, or LED therapy. Red LED lights do not contain any type of UV light,” so It is safe as long as it is used properly and there isn’t over-exposure. LED red light rejuvenates skin by stimulating fibroblasts to produce a little collagen and decrease the enzymes that break down collagen and promote the production of collagen and elastin. Both of these are known to increase the elasticity of the skin and keep it healthy and young looking. Elasticity is what keeps the skin smooth.
Red Light Therapy equipment is comprised of a light emitting device that emits light over a particular wavelength, depending on what the desired results are. For collagen production and wrinkle reduction the desired wavelength is red light that occurs between 615nm and 640nm. The light emitting panel is placed above the surface of the skin where treatment is desired.
