I have a problem with chin dimpling when I close my mouth. I have a weakened chin. Can botox fix this? (Photo)

Hi there-The "chin dimpling” that you are referring to is often also called peau d'orange, or “orange peel chin.”  This condition is caused by overactivity of the underlying muscle, called the mentalis.  Botox is quite effective for this problem, as it relaxes the underlying muscle and helps to smooth the skin.  Because the Botox stops contracture of the chin, it can appear slightly more prominent. As mentioned by my colleague below, a more permanent correction may involve augmentation of your chin, either with an implant or your own bone, as often the dimpling you are seeing is caused by straining of the muscles to cause closure of your lips. How to know which is best for you? Visit a Board Certified Plastic Surgeon for an evaluation.

Botox
is a great treatment to help soften the dimpling in your chin. Results generally last for about 3-4 months. 

Hi.  The muscle that causes the skin dimpling on the chin in your photo is called the "mentalis" muscle.  It responds well to treatment with Botox.  Often, the muscle is overactive in people who have a weak chin.
