Voluma is the filler we commonly recommend for penis fillers. Voluma is a Hyaluronic Acid, or H.A.   H.A is a naturally occurring substance made by the body.  This type of filler is generally more safe and is commonly used in the lips and face.  However, with the increased interest in penis enhancements, Voluma has been found extremely safe in the penis as well.  In fact, It has been used for about 15 years now.  This product is one of the lower risk options because it can be reversed.  Patients will need to repeat the treatment again to maintain their increased penis size.
