ARPW's fasciotomy is specially designed for facial and body care. It has four models: small ball knife, small fish knife, big M knife and small curved knife. These four types also have their own uses. If you use a small fish knife and a small ball knife to treat your face, the small ball knife can be used in the corner of your eyes, without letting go of any tiny places. Different parts of the body will also use big M knives and small machetes respectively. No matter face or body part combined with 448kHz+20kHz thermoelectric therapy, it can help the body relieve inflammation and promote microcirculation. Focusing on the face helps to fade fine lines and even skin color.
