Please tell me more on the 'cons ' of considering Voluma to fill sagging cheeks?

Hi Shayda. When done by an experienced injector there really are no "cons" to Voluma treatment. The results look natural and can last up to 2 years. The main risks of the procedure are related to the injection process: bleeding, bruising, swelling, etc. However, when done by an experienced injector these risks are minimal. Voluma can help improve the appearance of the nasolabial folds, however, depending on the degree of volume loss you may require additional filler to those areas also. Please find an experienced physician injector for this treatment. Hope this helps.

Voluma is one of my
favorite products for filling sagging cheeks. It looks very natural
and can last for up to 18 months, as it helps to stimulate new
collagen production. The poor outcomes that you describe are not due
to the product itself, but to injector error. For example,
discoloration is the result of placing the product too superficially.
If you work with a board-certified dermatologist who has many years
of experience sculpting the face beautifully and naturally with
Voluma, the only side effects you should expect are short-term and
related to the trauma of injections, such as slight bruising,
swelling and/or discomfort. These should resolve within days. You
also want to start conservatively – no more than one syringe per
cheek – and then add more later, if desired. Stretching of the skin
is not an issue with Voluma. Fillers stimulate some natural collagen
growth and actually strengthen skin over time.
Using Voluma alone
creates a lift that smooths out the nasolabial folds and mouth folds,
in an immediately visible way. If there are superficial lines too, we
often also need to use other fillers, such as Juvederm, Restylane or
Belotero, to even out those creases. Please consult a board-certified
dermatologist to find out how Voluma and fillers can help you
compensate for volume loss under your orbital rims, plus smooth out
nasolabial and other folds.  

Our practice is one of the busiest Voluma injectors in the region.  We have had incredible results from the product and recommend it highly.  Voluma is natural, predictable, and durable (lasts approximately 2 years).  The "con" is potentially the higher cost.  Most patients require more than one syringe and Voluma is priced higher than most of the other fillers.  Consider Sculptra or fat transfer as potential alternatives in your decision making.  Best of luck!
