CELEBRITY MAKEUP ARTIST MATIN'S PICK. “Freeze” away the signs of aging with the SiO Cryodrop, a professional level skin-toning tool that uses the power of cold therapy and massage to visibly lift, tighten and sculpt facial contours. The diamagnetic heart of the tool effectively delivers key ingredients deep into the skin’s dermis by propelling the positive ions of the SiO Energy Serum into the negative ions of the skin.
