Dimple Chin, also known as 'Orange Peel Chin' or 'Pebble Chin' is caused by repetitive movements of the mentalis muscle of the chin. Over time, due to repetitive use of the mentalis muscle, your chins skin develops a pitted appearance (a sign of ageing). This however, all can be reversed with a few units of Botox injected into the mentalis muscle. This minimally invasive procedure helps to achieve a smoother chin and regain your youthful appearance with results lasting 3-4 months.
