When considering the use of Neuramis on top of Juvederm in your lips, it's important to consult with a qualified and experienced injector. Here are some key points to consider: Compatibility: Both Neuramis and Juvederm are hyaluronic acid-based fillers, which generally makes them compatible. However, each filler has its own formulation and properties, so mixing them should be done cautiously. Professional Assessment: It's crucial to have a thorough assessment by a licensed practitioner who can evaluate the current state of your Juvederm filler and determine if adding Neuramis is appropriate for your desired outcome. Timing: Consider the timing of your previous Juvederm injections. Your practitioner can advise you on the optimal interval between treatments to ensure safety and effectiveness. Potential Risks: Combining different brands of fillers can increase the risk of complications such as lumps, uneven texture, or prolonged swelling. A skilled injector will have the expertise to minimize such risks. Custom Treatment Plan: Your practitioner can tailor a treatment plan that considers your aesthetic goals and the characteristics of both fillers to achieve a natural and satisfactory result. Ultimately, the safety and effectiveness of mixing fillers depend on the skill and judgment of your injector, so it's essential to choose a qualified professional for your treatment.
