Dermal fillers are injections which are placed under wrinkles or deep lines to help reduce their depth and soften their appearance. They are also used for lip enhancement.
The commonest type of dermal filler consists of Hyaloronic acid, a natural substance which exists in the connective tissue of the body but has been artificially synthesised. It is not permanent and will dissolve over time.
A number of companies make dermal fillers such as Restylane and Juvederm.
The use of permanent dermal fillers should be avoided on the face.
