I'm 31 and starting to get some smile lines around my eyes. I was happy to get this sample and I used it every night until it ran out. It felt soothing and nice around my eyes, but I didn't really notice a difference in the appearance of lines. It did feel nice and warm going on though, so I'm sure it was doing something -- maybe preventative for further development of line, but I couldn't really tell. Maybe if I'd used it longer.
