I have had 4 syringes of Radiesse injected in the back of my hands $$. (photo)

4 syringes of Radiesse should have given you much more volume.  You should see if the radiesse was diluted or if this is truly what was injected.  If you have an area to harvest fat, this may be a better option for you as it would give you more volume and may last longer.  I suggest seeing a filler expert for treatment.  Veins can also be treated with sclerotherapy which can really rejuvenate the hands in some cases.  You should see if you are a candidate.  Best, Dr. Emer.

I encourage you to explore Renuva. This product is specially designed to address age related volume loss. It is similar to traditional HA fillers in that you will see some improvement immediately. However it differs in that over time the product is gradually replaced by your own fat. This gives longer lasting results. See my website or a provider near you to learn more.

Thank you for your question, and the photos. We get this question often. Radiesse is supposed to last 1 year.  Those who move their hands excessively will have it wear off sooner.  Each patient is different, and may need more or less product.  In Las Vegas, we get many card dealers who take pride in the appearance of their hands, as that is what the public sees.  Often the aging had will have more visible vessels and tendons.  The hands may also have solar damage, or just aging changes to the skin.  We often will inject patients with Radiesse to add volume to the hands and decrease the harsh appearance of the vessels and tendons.  Radiesse is FDA approved for this.  We often will follow this up with appropriate peels to help smooth the coloration and give the skin a more vibrant look.  Best to see a Board Certified Plastic Surgeon.  They have had multiple years of hand surgery training, and know hand anatomy and function well.   Some, (like our office), have had additional hand fellowship training.   They are also well versed in how to best treat the skin, as they diagnose and operate on it.

Radiesse is a stimulatory filler so it may take some time to see full effects. Take before and after photos and speak to your injector about your concerns. Best, Dr. Karamanoukian Los Angeles

Based on my experience, 2 tubes of Radiesse injected to each hand should have produced more of a result.  However, you should find out whether the larger 1.5 cc syringe or the smaller 0.8cc was utilized.  Nonetheless, everyone is different and what works for most people unfortunately does not work for all.  I would go back to your doctor and discuss your results.
