I am considering Profhilo (am early 50's and getting first signs of jowls plus upper lip lines). I have searched and found a few posts of people saying it didn't make much difference, and am wondering if anyone has had a positive experience? The reason I am considering Profhilo rather than fillers is that I have not had any 'work' done previously and want a subtle effect that just slows down aging, rather than to fight aging completely.
