Is there a difference between how deep voluma vs. Radiesse is injected in the temples?

While fillers injected into the temples tend to be injected more deeply than other areas of the face, the specific depth will depend on a variety of factors including how much correction is needed. These two products work in different ways and therefore might be administered differently to achieve the desired result. Voluma is a hyaluronic acid filler that provides support within the dermal structure to restore youthful volume. Radiesse is a filler containing calcium hydrospheres that serve as a type of scaffolding in the dermal structure to provide volume right away. At the same time, the formulation stimulates the body to produce more collagen, for additional support over time. 
If you are working with an experienced, board-certified dermatologist with expertise in dermal fillers, you can rest assured that your doctor will choose the appropriate filler at the appropriate depth to create an optimal outcome for you. 

Great question!  Radiesse and Volume are thick products and should be injected in the deeper planes of the tissue. Placing them too shallow can create a palpable and lumpy appearance.  Thicker products are generally placed in the deeper tissues, thinner products are generally placed in the more superficial tissues.  So depending on your desired results will depend on what products are used. Best of luck and hope this information helps!

Thank you for your question. The depth of the filler will depend on a variety of factors, including the amount of filler needed and the preferred injector technique. Radiesse and Voluma are usually both administered deeper below the dermis and also right on the bone to create smooth, natural fullness. Sculptra, which works by stimulating collagen production, is usually injected in similar areas. Usually it is safest to inject right on the bone with a depot technique in the temple, to avoid blood vessels and complications. Occasionally, I will add a hyaluronic acid filler subdermally, using a cannula in this area if needed. If you are working with an experienced, board-certified dermatologist, rest assured your injections will be placed with the precision necessary to obtain an optimal outcome for you.
