There has been some debate about this here and there but never a survey as far as I know.

One side suggests that Str8t shaving may make you look older due to all the stretching of the skin repeatedly.

The other side argues that because wetshavers use more and better health products : soaps/creams with moisturizers, WH and alum, balms and healing lotions that take better care of their skin and therefore look more youthful in their old age.

I love wetshaving too much to ever give it up so I really don't worry about such things myself
