Wide lower face.

The test: clench your teeth firmly and feel the jaw angle. If a hard muscle bulges out, the masseter is involved – the most common cause, often from teeth grinding. If it stays soft, it is fat (jowls, double chin) or the bone itself. Bone can only be changed surgically.

Masseter Botox: relaxes the chewing muscle, which shrinks over three to six months; the lower face becomes narrower, the shape more oval. Grinding eases as well. Two to three treatments in the first year, then usually less often. Not suitable for a narrow face – then it looks hollow.

Fat: jowls and double chin widen the lower face visually; injection lipolysis can reduce small deposits. For larger amounts liposuction is more effective.

Proportion instead of reduction: sometimes a face looks wide because chin or mid-face lack projection. One millilitre of hyaluronic acid at the chin can make the shape appear narrower without removing anything.
