Restylane injection method question for under eye hollows
Doctor Answers 5
Using a cannula can only get the Restylane in loose connective tissue where it does not stimulate collagen growth. A needle does enable the injector to inject the material intradermal. There is lots of scientific evidence that Restylane administered in the dermis does stimulate collagen and enhances strength and longevity. In other words; the cannula takes the material too deep to strengthen the skin.
