Corners Of Mouth Drooping Treatment

2nd September 2026

A radiant, attractive smile can boost confidence and well-being, but drooping corners of the mouth can detract from this positivity, creating a downward smile or a perpetually sad expression.

Botox is a popular treatment for droopy mouth corners (also known as marionette lines), a concern that becomes more pronounced with age due to a combination of factors. These include the natural loss of collagen and elastin, repetitive facial expressions, overuse of the depressor anguli oris (DAO) muscle, and loss of volume in surrounding areas. Smoking and genetics can further accelerate these changes, impacting the overall facial appearance and contributing to a sad mouth look.
