Silikon-1000 may be used safely, only by experienced physicians, for Permanent Lip Augmentation.
Silikon-1000 is a permanent filler, so your results, good or bad, are permanent. You must find a board-certified dermatologist or facial plastic surgeon experienced with the micro-droplet technique. You should also have a discussion with your doctor about the FDA's position with respect to using Silikon-1000 in an off-label fashion to enhance your lips. Lastly, you should see many before and after photos demonstrating beautiful, natural results before you pick your doctor and proceed.
