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.

I think Juvederm or Restylane (or other hyaluronic acid based filler) may be better for under the eyes. However, Radiesse is great for the cheeks.

RADIESSE® is a terrific filler, specifically because of its thick
consistency. This quality also makes it ideal for adding volume to the cheek
area with really beautiful, natural-looking results when you visit a skilled
injector. However, the very qualities that make RADIESSE® so great for other
areas are the same qualities that make it not the best choice under the eyes.
The skin around the eyes is very thin; not only can the RADIESSE® injections be
more apparent there, but the opacity of the substance may actually be visible
through the thin lower eye area skin. I’d recommend the cheek enhancement alone
to see how that affects the under eye area. If you are still unhappy, try a
different filler just under the eyes that is a bit more subtle.

Thanks for the great question. For the midface, cheeks, and under eye areas, I use a combination of different fillers. Radiesse is an excellent choice for building up the cheeks and highlighting the cheekbones. However, it is not an appropriate filler for the under eye area. In this delicate tissue, a thinner product is required. I use either Restylane or Belotero for this area, sometimes called the "tear troughs". In most cases, one 1.5ml syringe of Radiesse and one or two 1ml syringes of Restylane will give a fantastic, natural-appearing result.
