The Juvederm range of products use a specially formulated type of hyaluronic acid (HA) that exists naturally in the skin. It's a natural, biodegradable gel that flows easily and smoothly into the skin, instantly filling out troublesome lines leaving a smooth and natural look and feel.
Juvéderm Ultra 4 is an injectable hyaluronic acid based dermal filler that has an even greater volumising effect and is used to fill deep depressions of the skin via injections, as well as for lip enhancement and cheekbone augmentation. Juvederm Ultra 4 contains Lidocaine.
