Recessed Chin

How far the chin projects is largely decided by genetics, the inherited instructions that guided how the jaw and chin bone grew. A naturally recessed or short chin is a variation, not a flaw, but it gives the lower lip and the profile less forward support from the beginning. This concern is common in both men and women and has nothing to do with aging.

Bone is living tissue that constantly renews itself, and with age the balance tips toward loss, a process called resorption. The chin and the front of the jaw are among the areas where this shows most. As the bone slowly recedes, the chin shortens and projects less, and the soft tissue above it loses the base it was built on.

A pad of soft tissue, mostly fat, covers the chin bone and gives the chin its rounded, padded shape. With age this pad gradually thins, like a cushion compressing over years of use. The bone's outline shows through more, the chin looks flatter, and the crease between lip and chin deepens because the pad no longer fills it from below.

Collagen, the protein scaffold that keeps skin firm, declines from the mid-twenties at about 1% per year. Around the chin, thinner and less elastic skin settles more visibly into the labiomental crease and along the start of the neck. Skin quality does not cause the loss of projection, but it determines how clearly that loss shows.
