Thank you for your question leigh_crouch. Volbella is a hyaluronic acid filler designed to enhance the lips. It, along with Voluma and now Vollure (Volift in Europe), is a member of the Juvederm family which uses Vycross technology. This means multiple sizes of hyaluronic acid are used and it leads to a longer duration. Each of these products contains a different level of hyaluronic acid. Volbella, Vollure, and Voluma contain 15, 17.5, and 20 mg/mL of hyaluronic acid, respectively. Volbella is a thin product that works well in fine lines such as those around the lips. Voluma, on the other hand, is thicker and works well for volumizing and lifting the upper cheek. Vollure is intermediate and works for areas such as the nasolabial folds and marionette lines. Please consult with a doctor for specific recommendations. Good luck!
