Should I stretch the skin while Double Edge shaving?
Before I took up straight shaving, I never stretched my skin at all DE shaving.
One day I decided to stretch my skin during my DE shaves too, and found the results to be much improved.
Now I wouldn't shave without stretching the skin.
According to Mantic stretching the skin can lead to ingrowns for some people, however, I doubt it causes ingrowns for the majority of people.
I would say give it a try, and see what the results are.
I thought the guard bar did that for you ( stretch the skin )
