First let me compliment your injector for achieving significant improvement in your dynamic glabellar wrinkles, but not leaving you incapable of motion. Back in the early 1990s, when I first started using Botox for aesthetic purposes, we mistakenly thought that it was necessary to "freeze" muscles. It took us some time to learn that this frozen, porcelainized look and inability to emote was artificial and did not contribute to a natural look. Think about it. If you look at a five year old child, you will see a nice, smooth, wrinkle-free area between the brows. But, just refuse to give that child ice cream and watch how deep a frown that child is capable of making. So, contrary to outdated conventional wisdom, the intent of treatment with neuromodulators (such as Botox, Dysport, and Xeomin) nowadays is to diminish dynamic (motion-related) wrinkling, not to eliminate it entirely. In your case, the residual static (lines at rest) eleven line creases (etch-in lines) present have resulted from years of folding the skin with facial expression, which lead to a situation akin to the creating a permanent crease from repetitively folding a piece of paper. Fillers can be helpful for these residual, static lines,. My preference is Belotero Balance in my NY office and for Teosyal Redensity II or Alaxian FL in my Israel satellite facility, where a far greater number of regulatory agency approved fillers are available. Make sure you are seeing a board certified aesthetic physician.
