I am 53 and I noticed those darn pesky folds along the sides of my nose. I did some research and then was lucky to find an excellent doctor. My 'Doubting Thomas' husband thought it was a waste of time and good money, but he went with me. (I previously had Botox and he did not see any great results.) After I came out he actually was amazed. He said I looked wonderful and he was taken aback by how quick the results were. It lasted a very long time, over a year. I had it again and it has even lasted longer the second time. I really feel the best results are achieved when you have a qualified doctor perform the procedure. After all, it is the artist, not the paint that makes a painting beautiful.
