Hello! My name is Jessica, I am a physician assistant, and one of the providers at Aesthetic Skin in Winnetka and Chicago. This is a great question. After receiving Sculptra injections, it is important to monitor the treatment area for any changes, including the formation of nodules. Typically, Sculptra works by stimulating collagen production, which may initially create small lumps or nodules. These are usually temporary and can resolve as the product integrates into the tissue. In most cases, nodules should not grow larger over time. However, if you notice that they appear to be increasing in size or becoming more prominent, it is advisable to consult your provider. They can assess the situation and determine the best course of action, which may include massage techniques or additional treatments to help manage any concerns. I hope this helps and best of luck!
