$700 seems kinda steep, but I guess not for miami beach. I go to harmony wellness in coral springs and the nurse practitioner does it, only $550. Love my results, first time doing Perlane, have done restylane many times before but I wanted my lips fuller and I know what you mean when you say you smile and the upper lip disappears. I also get my lip wrinkles injected and botox'd. Hopefully this will last longer than the 4 months I get out of Restylane!
