Filler or PDO thread lift? (Photo)

Your photos show a beautifully contoured face. There is no sagging skin apparent to indicate a thread lift. If you would like more definition to your cheeks you could consider filler to naturally enhance your facial contours.

First, let me say, that, at least from the photos, you do not appear to need any work at this time. And unless an in-person examination reveals something different from what is seen in the photos, you appear to have a beautiful and properly proportioned face. Just for general information, I gave up threads years ago, since the results do not last as long as promised and a recent paper reported an unacceptably high rate of adverse reactions to them. On the other hand, fillers, particularly of the hyaluronic acid-based variety would, in my opinion, be a far better route to go. For now, relax. Best of luck.
