Overview of facial aging.

Facial aging is a multidimensional, multifactorial process. The aging face has traditionally been treated by each specialty in a different manner. However, by understanding the process from the perspective of different specialties, each physician may better treat the spectrum of facial aging. Whether or not the facial plastic surgeon injects products to restore volume, uses lasers to resurface the epidermis and dermis, incorporates cosmeceuticals to enhance and maintain improvements in the skin integrity and appearance, or relaxes muscles with botulinum toxins, he or she can best advise patients and address facial aging by having a functional understanding of these various modalities. With this knowledge, the facial plastic surgeon can parse the component of facial aging that enables him or her to correct each with the appropriate treatment. Thieme Medical Publishers.
