Hi! I'm a woman, age 25, just starting to notice the first signs of aging, and unfortunately, those are most noticeable under my mouth! I've attached a photo for reference. If you look in the photo underneath my lips you can see two sort of "pouches" or indentations (more so on one side than the other). I'm not sure if these are early marionette lines? These pouches lend an unhappy/bitter look to my face and age me. What can be done? Botox, filler? Open to any and all suggestions!
