The SmartAppGuided™ Sonic Warm & Cool Facial Mask uses a SmartSonic Pulsation Technology that gently shakes loose dirt and invisible makeup residue on your skin through over 8,000 sonic pulsations per minute. Our proprietary Cryo Deep Cooling Technology instantly shrinks pores to a minimum to reduce puffines. By adding the Thermo Deep Warming Technology, Full Facial Hyper-Infusion Technology, and Full Spectrum LED Technology, the Facial Mask helps your skin to take in the active ingredients of your skincare products at a deeper level, where they can improve your skin in the most efficient way.
