Lip lift corner treatment (Photo)

First choice should be treatment at corners of lips with filler by talented injector.  For permanent result, "anguloplasty," or "corner lift" procedure.  These are both office treatments, local anesthesia.  Examples at link below.

Thanks for your question and photo. There are three types of corner lip lifts, each of which provide their own idiosyncratic benefits.The noninvasive route would be fillers plus or minus a neuromodulator such as Botox® into the depressor anguli oris muscle. This treatment route is good for mild cases. However, corner lip ptosis progresses with age. A traditional corner lip lift will elevate the drooping corners of your mouth while at the same time, help eradicate the small fold (marionette fold) that originates from the corner. The surgery can be performed under local anesthesia and results are subtle yet dramatic. The DAO release is performed within the mouth but is a less effective treatment option than a traditional corner lift (the effects of which can be predicted by injecting Botox ®  into the aforementioned muscle). A medial corner lip lift is one which elevates the corners of the mouth, lessens the marionette folds and also can directly reshape the lateral vermillion. It is essentially a "magic trick". Results are permanent, subtle and yet, as mentioned, very dramatic.

Injectable treatments like fillers and Botox can be tried first. But a corner of the mouth lift is the most effective and permanent solution. The mouth corners have to be physically relocated to a more horizontal position to achieve a long-lasting solution.
