Juvederm Fillers Explained

What Goes Where … and Why
In the last number of years, the types of fillers available for facial injection has increased dramatically. This article explains which kinds of fillers are best suited for different areas of the face.
The Juvederm brand, from Allergan, is the leading brand. It has different kinds of fillers depending on how they are cross-linked.
Hyaluronic Acid Cross-Linking
All Juvederm products consist of Hyaluronic Acid (HA). HA is a naturally occurring sugar in the skin which keeps the skin hydrated and plump. As you age, your skin naturally loses Hyaluronic Acid. As a result, the skin becomes dry and deflation occurs. Filler can be injected to address the collagen and fat loss and to reflate the affected area.
To make HA molecules into a stable, lasting filler, they are bonded together, or cross-linked, and suspended in water to make a gel. Depending on the molecular weight of the HA molecule, the tightness of the cross-linking, and the number of HA molecules per ml, different product qualities are achieved.
I like to think of an analogy such as a string of pearls. A string of same sized small pearls
looks different than a string of alternating small and large pearls. It would also have a different weight on your wrist.
2 Major Groups of Juvederm Products
The older Juvederm Ultra and Ultra Xc use Hylacross technology. This technology cross-links HA molecules of uniform molecular weights (think of the string of same sized pearls ).
The newer Juvederm Vol products use Vycross technology. This process cross-links higher and lower molecular weight (small and large pearls strung together).
The two types of cross-linking and the different weights of the HA allow products to be designed with different cohesively and elasticity. The difference in cross-linking determines which product is best in which site.
VOLUMA contains the thickest strongest gel and is best for a lift in cheeks, temples, and jaw area.
VOLIFT is a medium density product and is great for nasolabial lines, lateral cheek in thinner faces, and also in lips for the longevity of the treatment.
VOLBELLA contains the thinnest gel. It is perfect for lip hydration and tear trough areas.
VOLUX is a new product about to enter the market and will be used mostly in the jaw and chin area.
VYCROSS products tend to be a little more stable and last longer than Hylacross. So lip filler using Juvederm Ultra will give a great result but will not last as long as Volift for example.
Most often a combination of products will be used to achieve the results you are looking for.
A skilled injector will have had extensive training in the use of all these products and will know which filler will give the best and longest-lasting results.
