Clinical studies have shown that skin cells grow 150 to 200% faster when exposed to certain LED light wavelengths. That's why Lift Care brings you Rejuven Light. It's an LED light therapy system using four wavelengths of UV-free LED lights to boost collagen production. Blue, Yellow, Green, and Red Light therapy, when used in skin treatments, promotes a variety of benefits for wrinkles, aging, acne, stretch marks, and elasticity. This device is easy-to-use - simply select your desired LED attachment and glide it over your face. Hold it still on each quadrant of your face and use it daily for 10 to 12 minutes for better results. The results from LED light therapy are cumulative, you'll receive additional benefits from doing a treatment every week for eight to ten weeks.
