What is the difference between Silicone and Silikon 1000? Which one is safer? If I was to decide to have Silikon 1000 or Silicone injected into my lips to enhance them, could I inject another filler after? What I mean by this is that I do want my lips bigger, but I do not want the end results forever. I rather have a nice sized pair of looking lips when I'm old instead of the results I really want for the time being.
