The Cryodrop has a magnet with a lifetime charge. The Serum contains ingredients with diamagnetic properties. This means that when they are used together, the diamagnetic properties in the serum are repelled by the magnet. When the Cryodrop massages in the serum, the diamagnetic force from the tool gently pushes the diamagnetically charged ingredients deeper into the top layer of the skin. The technology is gentle and completely safe for use. There are no safety concerns posed with the use of this serum.
