Hello, thank you for posting your question and photos. Nasolabial folds, or smile lines, can become more prominent with age as the skin loses elasticity and volume. Fortunately, dermal fillers offer an effective solution for treating nasolabial folds and restoring a smoother, more youthful appearance. By carefully injecting filler into the area around the folds, a board-certified facial plastic surgeon can plump up the skin and reduce the depth of the creases. RHA fillers are popular for deep nasolabial folds because they mimic natural hyaluronic acid produced in the body for more natural results. RHA fillers are also long-lasting, up to 18 months, and can be tailored to meet your needs with four different formulas. 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.
