What is saline removal?

Salt or saline removal operates based on the principle of osmosis. Osmosis is the process whereby solvent molecules, typically water, move through a semi-permeable membrane, such as skin, from a region of lower solute concentration to one of higher concentration. This results in achieving equilibrium, where the concentration is the same on both sides of the membrane. The movement of water serves to balance out the proportions of salt to water.

By introducing a higher concentration of salt or saline solution than naturally present in the body, osmosis is initiated. When Li-FT® is introduced into the upper dermal layer, where the unwanted pigment resides, this process commences. Water within the cells beneath the pigment, with lower salt concentrations, is drawn upward towards the area with higher salt concentrations. 

Equilibrium compels the pigment from the dermal layer to migrate towards the epidermis due to osmotic pressure. This natural process aims to equalize the higher concentration of salt and water. As a result, the pigment becomes trapped within the scab, and upon the scab's detachment, some of the pigment is carried away with it.
