This is the latest v3 kassa with radio wave function, renewed in 2021. I purchased it at a beauty salon and opened it once to check the contents, but I have never used it and have kept it carefully stored. ◆ Condition: New, unused ◆ Product Name: V3 aggressive kassa RF ◆ Model Number: YDF-25B ◆ Retail Price: 38,280 yen (tax included) I will include the instruction manual and send it in its original box. 【Effects/Performance】 When RF (radio waves) are emitted, the heat generated (Joule heat) stimulates deep within the skin, promoting collagen production. By generating new collagen, it tightens the skin from within, giving it firmness, and can improve sagging and wrinkles, leading to a lifting effect.
