Is there a difference between how each of these 3 options look? I know that the latter 2 are non-reversible and also build collagen but I just wondered if they look the same in the short run when injected? And do any of them do a better job on deep wrinkles than others? I saw a demonstration of a doctor injecting standard filler at an open evening once and I have to say I was underwhelmed but there are photos of sculptra/ellanse on the website I'm considering and they look amazing. Is this just good marketing and/or an unusually poor result in the demonstration (maybe the individual injected just didn't have that bad wrinkles to begin with)?
