Hello SarahGG, and thank you for your question about the safety and permanence of Silikon 1000. Silikon 1000 is a permanent filler composed of liquid medical-grade silicone, and while it has been used off-label for cosmetic purposes, I do not consider it a safe option for most patients. Its permanence makes it particularly risky, as complications can occur years or even decades after the initial injection. The risks associated with Silikon 1000 include migration, where the filler shifts from the injection site over time, causing lumps, deformities, or asymmetry. It can also lead to scar tissue formation or granulomas, where the body reacts to the silicone as a foreign material, resulting in hard nodules or chronic inflammation. These reactions are unpredictable and can worsen over time. If complications arise, the only solution is surgical removal, which is invasive and may result in scarring or permanent deformities. In areas like the lips or face, removing silicone can require excision of the affected tissue, which may irreversibly alter the shape and contour of the area. While Silikon 1000 might initially provide good results, its long-term risks often outweigh the benefits. If you are considering fillers, temporary options like hyaluronic acid-based fillers (e.g., Juvederm or Restylane) are much safer and allow for adjustments over time. These fillers can also be dissolved if necessary, providing far more flexibility and fewer risks compared to permanent fillers. I hope this helps clarify the safety concerns and long-term implications of Silikon 1000. Please consult with a board-certified plastic surgeon or dermatologist to explore safer, more reliable options for achieving your goals. Sincerely, J. Timothy Katzen, MD
