I am scared to do injections under my eyes, so I am wondering if Radiesse in my cheeks will also help my eyes?

I think Radiesse is a great product for areas that need alot of volume, such as the cheeks or even the hands, but I would not use it underneath the eyes. The lower eyelid skin is very thin and will not tolerate thick product like Radiesse. In these cases, I will use Radiesse for the cheek volume and then Restylane for the lower eyelids. This gives a very nice overall balance to the face, and improves one of the classic signs of aging, which is volume loss.

Radiesse is a wonderul filler for lifting the cheeks, contouring the jaw and filling the backs of the hands.  It should not be used in the hollow under the eyes as you it appear lumpy and irregular.  However, when the cheeks are lifted and contoured in an artistic manner, the cheeks will help to fill the hollows seen between the lids and cheek areas.  Using Voluma and Radiesse the face can be mid-face can be sculpted, lifted and rejuvenated. 

Radiesse (Calcium Hydroxyapatite) is an effective filler for deeper injection, and can certainly be useful for addressing cheek position and increasing fullness.  It has to be used carefully, and it shouldn't be injected under the eyelid, due to the thinness of the eyelid tissue, and thickness of the product.  However, when injected along the cheek bone, the tissue is often slightly lifted, which can decrease the appearance of under-eye hollowing.  If hollowing remains, I typically use a thin hyaluronic acid filler like Belotero or Restylane to further improve the appearance of the tear trough.  These are safer fillers for injection in that region.
