Lip augmentation is a very popular and safe procedure. Typically filler of some kind is inserted into the lip either as an office procedure or combined with another procedure in the operating room. Implant materials can be either natural or synthetic. Using natural materials, such as fat, requires a longer recovery and is associated with more swelling, but can achieve longer lasting results. Off-the-shelf injectable materials are very popular and can easily performed in our office. We suggest making small changes over time, to avoid an over-done and unnatural appearance. The materials used for injection are proven to be safe but are only expected to last for periods of months at which time a repeat procedure might be desired.
