Dear 909 baby,
Morpheus 8 is a great option for collagen stimulation, and helping with lifting jowls and can help with contouring your lower jaw line and nasolabial folds. It works by creating small micro injuries that help stimulate your own body's collagen and help remodel your skin and underlying tissues. You have some volume loss that I can see from your pictures, underneath your eyes and mid face, cheek area. Nasolabial folds are also treated with fillers in areas of volume loss and with PDO threads to create a lift and collagen stimulation. You may need combination treatments to see satisfying results. In your case, I think Morpheus would be a good option to try starting with lower settings and more treatments, gradually, so that melasma and hyperpigmentation will not be an issue.
Hope this helps.
