What is the difference between Juvéderm Volbella and Juvéderm ultra plus, does one plump up the lips more?

In terms of adding lip volume, there is a WORLD of difference between Juvederm Ultra Plus and Volbella.  The differences start with the basic hydrophilic nature of Juvederm, which leads to a pleasing volume enhancement of the lip.  Juvederm Ultra Plus comes in a 1 mL syringe, while Volbella is packaged as a 0.55 mL.  Volbella, being far less hydrophilic, gives a more subtle result and is more suitable for finer lines.  

Thank you for your question. Both products are made by the same manufacturer which is Allergen. The difference between them is their consistency. Volbella is a thinner product which is great for subtle changes and fine lines, whereas Ultra Plus is thicker product and used for adding more volume. I recommend have a consultation with an expert injector to discuss your concerns and determine the best treatment plan for you. Best of Luck!
