Juv�derm ULTRA SMILE is specifically for your lips to create natural, smooth, beautiful results. Juv�derm SMILE contains biocompatible hyaluronic acid which is an injectable filler that provides instant results that are natural so no one will guess anything has even been done. Hyaluronic acid (HA) is a natural substance found inside the human body. It�s key properties are to keep the skin hydrated whilst adding plumpness. HA naturally breaks down in the body during metabolism and is then replaced. However as we get older and our metabolism slows down, replacement of HA is less often which results in less hydrated skin and less volume in the skin. Medical professionals have been using HA in arthritis treatment and during eye surgery. Juvederm Ultra Smile is a leading filler used for enhancing lip volume. The gel containing lidocaine can be administered without any pain due to its smooth consistency. The effects can be seen for up to 12 months. Pregnant or lactating women should not use Juv�derm ULTRA SMILE.
