Why does my chin stick out and how can I fix it? (Photos)

It’s completely understandable to feel self-conscious about your chin — even small differences in facial balance can really change how we perceive our profile. From your description, it sounds like you may have what’s called a prominent or projecting chin, which can happen when the lower jaw (mandible) extends a bit forward in relation to the upper jaw or when the soft tissue and muscle around the chin (the mentalis) are more pronounced.

When you push in your lower lip and the chin appears smoother, that movement temporarily relaxes the mentalis muscle, which can make the chin look less projected — that’s a helpful clue about what’s contributing to the look.

Here are a few possible approaches, depending on the cause and how much correction you’d like:

Botox (or similar neuromodulators) – Small doses can relax the chin muscle if part of the projection is due to muscle tension or dimpling, giving a softer, smoother contour.

Dermal fillers to the upper lip or chin area – Can subtly balance the profile and reduce the appearance of chin prominence without surgery.

Chin contouring surgery (genioplasty or reduction) – An option if the prominence is mostly bony and you’re seeking a more permanent change to facial proportions.

Your observation about the “pushed-in” look helps guide what might work best — often a gentle, non-surgical approach can already bring harmony and balance to your features while maintaining your natural expression.

At least from the photos provided, there appears to be a rather deep "mental crease" (the horizontal deep furrow (in this case) that runs all the way across the lower face and extends all the way from under the lower lip and over the chin. Such a deep furrow can make the chin appear to protrude.
If this is indeed the case, the use of a robust HA lifting filler can be used to elevate the furrow and in so doing diminish significantly the appearance of the "protruding" chin. In the hands of an experienced, board certified cosmetic dermatologist filler injector expert, treatment should take no more than about five minutes to perform and yield immediate results. Hope this helps and best of luck.
