The present research aims at preparing and characterizing different formulations of SBR1712 rubber with different loading amounts of two inorganic fillers: conventional N330 carbon black, new nanometric aerosil 200 fumed silica and local micrometric volcanic tuff.
Elastin and collagen loss from the dermal layer is essential cause for wrinkles in
the face. Dermal fillers is the solution for this problem and this study compared clinical improvement
degree and the duration of correction between hyaluronic acid (Matrigel) versus bovine collagen (Zyplast)
for the correction of nasolabial fold.
