Have been experiencing a rapid turn over time with both Radiesse and Sculptra. Been getting filler injections in my gaunt (heredity) temples and cheeks for over 9 yrs and lasts rarely more than a few months.
My doctor is baffled; don't have enough fat to transfer. May be active lifestyle/metabolism. Still looking for a more lasting affect. I am not underweight either. Radiesse gives immediate gratification but have problem with shadowing/see-thru affect and contour irregularities in some places.
Never let it be injected into top layers of thin skin areas- I have experienced scarring.
Overall, a skilled MD can do wonders with this product.
