Soft tissue augmentation: nonsurgical approaches to treatment of the mid and lower facial regions.

Fillers are playing an increasing role in dermatology practice, complementing the use of laser and other procedures used in skin rejuvenation. Prior to the injection of any filler, the patient should be counseled about what to expect in terms of any discomfort that may occur during or after injection, possible side effects, the results that he or she can expect, and the likely durability of correction. Knowing how and when to use dermal fillers throughout the face can help clinicians confidently educate patients regarding the full range of rejuvenation procedures that are available.
