Aesthefill is made of PLA(poly-Lactic acid )which is biocompatible  and also used in materials for lifting threads.It naturally stimulates the skin sells to produce its own collagen.
PLA is an aliphatic thermoplastic polymer derived from 100% renewable resources,such as corn and potato starch.
Through polymerization,PLA results in Poly (PLLA) and Poly( PDLA).The chemical and physical properties of these PLA are completely the same.
Since no surgery needs to take out biodegradable PLA from the body ,PLA prevents chronic problems or nuisance from eliminating non-degradable polymers that are left in the body after treatment
