I'm sorry to hear about the difficulties you're experiencing with dissolving the filler. Here are a few steps you can consider discussing with your healthcare provider: Re-evaluation: It's important to ensure that the product is indeed Croma Volume and not another type of filler that might not respond to hyaluronidase (Hylase). A detailed re-evaluation by your healthcare professional can help confirm this. Dosage and Technique: Sometimes, the dosage or technique used for administering hyaluronidase may need adjustment. Discuss with your healthcare provider whether altering these could improve the results. Time Interval: It may be beneficial to allow some time between treatments for the filler to break down naturally, especially if multiple attempts have been made in a short period. Advanced Imaging: Consider advanced imaging techniques beyond standard ultrasound, such as MRI, to assess the filler more accurately and guide further treatment. Second Opinion: If you're not seeing the desired results, it might be helpful to seek a second opinion from another experienced practitioner who specializes in filler complications. Alternative Treatments: Discuss potential alternative treatments with your provider, such as surgical removal, although this is typically a last resort and carries more risks. Remember to continue consulting with a qualified healthcare professional to explore the best options for your specific situation.
