Chroma Remover Saline Pigment removal system utilizes sodium chloride which works through the process of osmosis. When the remover is introduced into the skin, which is a semi-permeable membrane, water in the cells beneath the pigment particles will rise to areas containing higher concentrations of sodium chloride. This process is called equalization and forces ink from the dermal layer of the skin upward to the top layer of the skin. This method is safe and successful when done by a certified professional.
