Turkey neck is an unfortunate side effect of the aging process. The years give us so much: cherished memories, a wealth of wisdom and whatever comfort we’ve won in our youthful campaigns. But age takes a heavy toll, as well. Turkey neck emerges when neck muscles weaken and the skin loses its elasticity. That’s because springy compounds abound in supple, youthful skin; collagen and elastin hold things firmly in place. But as they gradually break down, the underlying muscle, called platysma, runs like over-easy eggs from your chin down to your clavicle (collarbone).
