Juvéderm Ultra XC and Juvéderm Ultra Plus XC are types of injected dermal fillers. Dermal fillers are a non-surgical treatment where material is injected into the skin to fill and smooth facial wrinkles and folds. Fillers can also be used for volume replacement, bringing back a more youthful appearance of the aging face and even hands. Juvéderm is made with a smooth gel hyaluronic acid, a component found in our own skin. Because of this, pre-treatment allergy testing is not necessary with hyaluronic fillers.
