FACES: Why They Matter and What They Reveal

The human face is the most private thing about us, and the most public. In his latest book, Professor Patrick Treacy asks why we want to change our faces — and what that desire reveals about identity, memory, and the way we are seen.

Drawing on four decades in aesthetic and regenerative medicine, Faces moves beyond anatomy to explore the face as a vessel for dignity and continuity: how ageing changes the way we are perceived, why patients so often seek not vanity but recognition, and where the science of beauty meets the deeper question of what a face is for.

A number-one release, and a thoughtful, medically grounded read for anyone drawn to the psychology of appearance, the science of ageing, and the meaning beneath the surface.
