Plexr generates a 4th state of matter called plasma (not the plasma in blood), using the air molecules in the tiny space between the device and the target skin. This plasma has a unique ability to gently sublimate (evaporate) the target skin. Aside from mole removal, all skin tightening procedures are not removing all the skin but just the very surface, leaving the underlying dermis intact. This is also typically done in a dot-like (fractional) pattern to avoid significant downtime. This process leaves carbon crusts which fall off in the coming days after treatment. Eventually the skin regenerates and it is this NEW skin which is the key. Plasma seems to trigger a powerful cascade of bioremodelling with new collagen and elastin being made. The skin thus becomes architecturally younger and therefore tighter. Plexr is the most powerful non-surgical skin tightening device that currently exists.
