Lettr630 is a skincare device that harnesses the powers of professional LED and massage therapy to give the consumer a high-tech pampering experience. The innovative gadget has been clinically tested in conjunction with the Korean Institute of Dermatological Sciences. The duration of the trial was two weeks and the sample size was 20 women, between the ages of 30 and 50. Each participant used the skincare device for 10 minutes every day and the results were noticeable — wrinkles were smoothed out by 37.22%, the membrane's collagen production had increased by 24.25% and pore size was reduced by 3.29%.
Lettr630 emits LED light and soft vibrations, thus not only illuminating and treating the skin, but helping moisturizers and serums penetrate deeper via massage therapy.
