Juvederm Ultra 2 for Nasal Folds and Below Jowls?

Most of the injectable fillers on the market have been initially developed and approved through the FDA processes for the nasolabial creases.  Injections to the marionette lines below the corners of the mouth are effective for early stages, bu for severe lines, the extra volume may only serve to make the cheeks heavier and accelerate drooping and jowling.  I am very conservative in this region.  Do ask your surgeon about alternative choices before having them filled up with volume that you may not actually need.

The Canadian fillers are slightly different from what we have in the United States, but it is wise to not change needles from what the company suggests to be used per that syringe.  Different viscosities of the fillers could make it dangerous to use a different needle and if it's too small in its lumenal diameter for the thicker filler, the needle might fly off the syringe during the increased pressure used to try to force filler out of the needle.

Juvederm is great for the nasal folds and for the lines around the chin. Juvederm is great here because it's soft and will feel like the tissues around it. The hollows of your cheek may be best treated with Radiesse. Radiesse has slightly larger particles than juvederm, it lasts longer, and is great for adding volume to hollow areas.

I prefer Radiesse for the depressions you describe. It lasts 2 or more years while juviderm lasts up to a year.

Juvederm products are appropriate to use for all of your areas.  Fortunately, in Canada we also have Voluma which is the thickest form of Juvederm.  Your discomfort can be minimized with an anesthetic cream and ice.  You should have treatment with a board certified dermatologist or plastic surgeon who is experienced in using all of the Juvederm products available in Canada.
