Combining Juvederm Ultra and Juvederm Ultra Plus can be an effective strategy to achieve your desired lip volume and contour. Both fillers are made from hyaluronic acid, but they have slightly different formulations and consistencies. Juvederm Ultra is typically used for fine lines and moderate volume enhancement, while Juvederm Ultra Plus is thicker and can provide more substantial volume and lift. Layering Juvederm Ultra Plus on top of Juvederm Ultra can create additional volume, which may help maintain fullness once the initial swelling subsides. The thicker consistency of Ultra Plus may also contribute to longer-lasting results. However, the final outcome will depend on several factors, including the skill of the injector, the specific areas being treated, and your individual anatomy. It's important to discuss your goals with a qualified injector who can tailor the treatment to your needs. They can assess your lips and recommend the best approach to achieve a natural and balanced look. Always ensure that any procedure is performed by a licensed and experienced professional to minimize risks and achieve optimal results.
