Unfortunately, most of us are our own worst critics. The marionette lines seen in the photos are by no means particularly deep, and yes, in the hands of an experienced, board certified cosmetic dermatologist filler expert, can be quite easily and quickly treated with filler in order to elevate and straighten the angles of the mouth. Treatment, in the hands of an expert, should take no more than about fifteen minutes to complete, engender little to no significant downtime, and yield immediate, on-the-spot results. I just did exactly this for myself just this past Friday. So, no need to despair and btw plenty of people in their late twenties already have these, as well. So, relax. Just make sure to consult with a filler specialist. Best of luck.
