Hi thank you for your question and posting a photo of the problem area. There is some sagging in the mid and lower face, as evidenced by the prominent nasolabial folds and marionette lines.
There are a few treatment options available depending on degree of invasiveness that you are comfortable with. I would recommend some lifting via non invasive HIFU (high intensity focused ultrasound) as well as volume replacement in the temples, mid face and buccal area with fillers.
For a more dramatic result, you could also consider bio-absorbable threads that help reposition the sagging fat pads. Last, but not least is the surgical facelift.
The best treatment for more severe sagging would be the surgical facelift but it is not without downtime and General Anesthesia risk.
Do speak to your preferred Doctor regarding the pros and cons of each treatment to choose the one that is best for you.
