Lately, there has been a lot of talk & 'buzz' over these injectible fillers. Some last a short time, some last longer. THere's everythng from collagen to Restylane to Sculptra & many more. I've seen the impressive 'before & after' photos, but I've never met anyone who was willing to admit that they've used them & dish about the experience. These injections can be prohibitively expensive & must be repeated to get 'optimal results' & later repeated to maintain the effect as the products wear off. In the long run, surgery is much cheaper & longer lasting. Has anyone here tried these injections? What did it cost & what were the results? Thanks!
