i personally would never self inject. i am a huge fan of fillers but the medical knowledge needed to properly administer juverderm in a safe way should be relative to that of a doctor or fully trained nurse. the nerve ending and muscle stucture of the face is extremely complex and needs a professional to administer. cheaper products bought online may not be safe and i think your face is too precious to do this yourself to save a few pounds. please think twice before doing this the results can be disasterous.
