Professional Skin Tightening Device The Time Master Pro is a lightweight device that uses professional-grade low-frequency ultrasound to activate skin metabolism and stimulates the regeneration of skin cells. The skin feels tighter as you use the device for immediate and lasting anti-aging improvements. Oxygen to the cells increases and waste is removed from the pores throughout your treatment. Ultrasound vibrations at 90,000 waves per second with only a slight warming of the skin. The device measures the same frequency as a professional-grade laser device, but the energy is low and does not damage the skin like the heat from a laser treatment. Ultrasound waves cause a vibration of the surrounding skin tissues, which removes wastes, strengthens, lifts, and plumps the skin. The rapid oscillation of tissue action of ultrasound will induct collagen. The skin tightening and the plumping effect occur as you are using the device.
