Purchased in 2021, used about 5-10 times. I'm selling it to organize my belongings. This is the same performance as the facial mode on the CAVIMAX Perfection sold by Miyako Chemical! EMS and ultrasonic sonic can be used simultaneously, and the titanium probe side has a single electroporation function. Sonic gel can be substituted with commercially available products, and you can use your own serums for introduction. Use it on your face, décolleté, and neck for about 5-10 minutes ( ¨̮⋆). Recommended use is about 1-2 times a week! Operation has been checked before listing. EMS, electroporation, and sonic functions are all working well. You can use it without any problems. The exterior doesn't have any noticeable stains and is in overall good condition! Please understand that there may be minor scratches. There is no stickiness or rust on the electrode surface! It has been thoroughly cleaned, so you can use it immediately upon arrival ( ¨̮⋆). Even if you are new to Mercari, feel free to ask any questions. I will respond thoroughly. For those who understand that this is a used item, please consider purchasing!
