Juvederm Ultra XC
Juvederm Ultra XC is a very versatile HA based filler. Like the other more commonly used hyaluronic acid based fillers, it includes lidocaine to improve the comfort of injection. Studies have shown its effects can last up to one year. This does depend in large part on the area of injection. I like to use it in the lips to add volume. I also like to use it in the melolabial fold (commonly called the nasolabial fold) as well as the marionette lines. These are the lines that are found around the mouth. When used in the lips it will last around 6 months. The reason is that the lips are very mobile which tends to make any filler go away faster than a less mobile area such as the cheeks. It tends to pull in more water (hydrate more) than some of the other fillers which makes it ideal for adding fullness to the lips and softening the deeper folds around the mouth. However, this makes it less than ideal for very fine lines or the tear trough area because in these areas it tends to look to full and lumpy.
