The Aging Face: When aesthetic medicine is enough and when the patient needs a plastic surgeon

Every sign of aging has an address. Do you know which one you're treating?

A deep nasolabial fold. A hollow tear trough. A softening jawline. Two patients can show the same sign for completely different reasons. In one it's bone, in another fat, in a third ligaments or skin. Treat the wrong layer and you get the face everyone recognises: heavier, wider, and no younger.

In this lecture, plastic surgeon Dr Marco Castrechini takes the aging face apart layer by layer and puts it back together as a clear clinical method. For seven of the most common concerns, you'll see what actually causes them, how to grade their severity with published scales, and where the line runs between what a syringe can fix and what needs a scalpel.
