This product is a four-wheel drive firming instrument. The two metal strips on the side interact with the two contact points of the head to generate a micro current, so as to achieve the effect of firming skin care. Depends on the form and follows the principle of function, and makes innovative design. This beauty instrument is inspired by architecture. It uses the triangular geometric form to carry out the extended design. The two metal strips and the key area are reasonably arranged on the three edges, which are cleverly integrated with the geometric form to solve the functional needs. The best hand-held grip is achieved through the twisted gradient body; and the 22 gold tilt angle is adopted on the head of the product to provide users with a more comfortable use experience. The multi-purpose design concept of one cover is adopted at the cap, which integrates ultraviolet disinfection and charging. When the user does not use the product, the skin cross infection caused by bacteria breeding can be avoided; at the same time, the integrated charging base reduces the user's use steps and provides the user with a comfortable and convenient use experience. At the same time, the simple and exquisite appearance also increases the product's identification in the market.
