Hello, thank you for posting your questions and photos. Dermal fillers are a cosmetic treatment option that can help address lines around the chin and mouth. These lines, also known as nasolabial folds and marionette lines, are common signs of aging and can make individuals appear older. Dermal fillers work by injecting a gel-like substance into the skin, which helps to plump up and smooth out these lines, resulting in a more youthful and rejuvenated appearance. Fillers like Juvederm and Restylane last around 6-12 months, and the results can be maintained with regular injections. This non-surgical procedure is quick and relatively painless, making it a convenient option for those seeking to improve their facial aesthetics. I recommend scheduling an in-person consultation with a reputable board-certified facial plastic surgeon and expert injector. They will be able to evaluate your concerns and treatment history, then determine the best course of action to achieve your desired results.
