It can be used by people with metal allergies, and is rust resistant, hard and tough, so is less likely to be scratched on the surface. It also reacts to light and has antibacterial action, so is always kept clean.

Q.Do I need to give a massage after giving treatment with the Naris Cavi 3S PRO?

No, there is no need to give a massage, but if it is for relaxation purpose, massage gently to help the lymphatic flow.

Q.Why do you equip your device with EMS? 

EMS has originally been used in medical equipment used for rehabilitation or as a solution for patients lacking in exercise and for those who are having difficulties to move due to illness or injury. With such background, EMS is often used in slimming equipment, and we also adopt EMS for our beauty device. Oscillating EMS at the same time can provide a pleasant stimulation to the body and the skin.

Unlike leg and arm muscles, which can be developed by exercising and training, facial muscles are difficult to train on an individual level. By using a device equipped with EMS, makes it easy to promote and support active muscle activity of the facial muscles and the inner muscles of the face as well.
