Cause & concerns

Small jaw bone

A small jaw bone is one of the biggest causes of an undefined jawline.

Related to genetics, people with a small jawbone often require braces and adult teeth removed. They also typically have a recessed chin.

Excess facial and under chin fat

Whether through weight gain or genetics, excess fat along your lower cheek, jawline and under chin causes a loss of jawline definition.

People with excess fat often have a fuller, heavier, rounder looking jawline.

Loose skin

As we age, our skin loses collagen and elastin, becoming saggy. Some people have naturally looser skin, even from a young age.

Having loose jawline skin reduces definition because it doesn’t drape well over the underlying jaw bone.

Treatment Options

Jawline augmentation

A jawline augmentation is a non-surgical option to enhance the definition of your jawline.

Depending on your anatomy, it can target many of the causes of an undefined jawline, and is a popular choice due to its convenience.

    The definition of your jawline depends on how the skin and fat drapes over the underlying jawbone.

    The larger your jawbone, and the tighter your skin sits over the bone, the more defined your jawline will be.
