Dermal fillers are a blanket term for a number of different products intended to add bulk or volume to areas that appear wrinkled or hollow, such as around the cheekbones. Fillers are recommended for application in certain areas of your face where volume is beneficial. This includes your lips, nasolabial folds or smile lines and "marionette” lines or the lines near your lips that seem to turn down. Fillers range in types from temporary to semi-permanent and tend to be priced based on how long the filler lasts. Fillers aren’t to be confused with another injectable material that treats certain wrinkle types.
