I have used Silikon 1000 in the lips for about ten years now, having learned from Jay Barnett M.D. in NYC who is likely the world authority on this treatment. I think that Silikon 1000 is an ideal filler for everywhere in the face but it is perhaps most ideal for lip augmentation. The results are outstanding and natural and I have hundreds of happy patients who would agree. Please let me know if I can be of further assistance.
