Silkn Silk ZPRO is a three-source rf beauty instrument of four-color brand. Its main function is to reduce swelling, lift and tenderness, and the effect is obvious.

Radio frequency (RF) is a kind of high-frequency alternating electromagnetic wave with a frequency between 300 kHz and 300 GHz. Radio frequency can penetrate the epidermis and act on the deep tissue, and the water molecules in the tissue move (rotate) and generate heat by friction through the rapidly alternating electromagnetic field, so that the collagen fiber is heated to about 55-65℃, and the thermal energy can immediately shrink the collagen fiber. In addition, the thermal damage caused by radio frequency can start the repair and regeneration of skin, and constantly stimulate the repair and regeneration of collagen, thus improving the problem of skin relaxation and aging caused by collagen loss. Simply put, when radio frequency acts on the skin, the heat energy generated by electromagnetic waves can heat the dermis. After heating, collagen cells under the skin will contract and tighten, promote the regeneration of collagen cells, and make the skin firm, full and elastic.
