Several things can be done to help improve the texture of skin on the neck. Hyaluronic acid fillers can be injected into prominent creases. Because the filler molecules attract water, some physicians inject them evenly in small amounts over large areas to help improve the look of the skin. Topical hyaluronic creams can be used to improve hydration and texture (for example Teoxane or IS clinical's Hydracool serum). Also, topical retnoids or retin-a can be used to improve texture. Beyond those options are several others, including microbotox (small amounts injected in the deep skin instead of the muscle), IPL and laser treatments, chemical peels, and tissue tightening treatments like Ultherapy. I recommend an in person consultation with a board certified plastic surgeon to assess your options based on your anatomy and current skin care habits. Just realize that when it comes to improving skin texture, no one treatment is perfect, and results are best with combining treatments and repeating them regularly.
