Juvederm® Ultra XC & Ultra Plus XC are dermal fillers available from Allergan, the makers of Botox®. It is an excellent filler, especially for lips and nasolabial folds, as it tends to swell less than other fillers and generally lasts for around 12 months or longer. It creates natural and soft lips and can be easily used to define and/or enlarge lips. Juvederm® comes in two forms, Ultra and Ultra Plus.
