Fat-dissolving injections, such as those using deoxycholic acid formulations like Deso, are designed to break down and eliminate fat cells in targeted areas. If administered in the same region where dermal fillers have been recently placed, there is a potential for interaction between the two treatments. Here are some considerations: Proximity and Interaction: The fat-dissolving injections could potentially affect the filler if they are administered in close proximity. The process of breaking down fat might alter the surrounding tissue structure, which could, in turn, impact the position or effectiveness of the filler. Timing and Healing: Since your fillers were placed only three weeks ago, they are still in the settling phase. Introducing another treatment in the same area might interfere with this process and lead to unpredictable results. Volume Changes: Fat-dissolving treatments reduce volume in the treated area. This might alter the aesthetic balance achieved with fillers, especially if the filler was used to create a specific contour or volume enhancement. Consultation with a Professional: It is crucial to discuss your specific situation with a qualified practitioner, ideally the one who performed your filler treatment. They can provide personalized advice and assess whether it is safe and appropriate to proceed with fat-dissolving injections at this time. To ensure the best outcome and avoid complications, it’s important to coordinate these treatments under the guidance of a skilled and experienced aesthetic professional.
