I have been shaving for a while, and i got my style down, very close shave, normally rash free. But today i shave, first time i 2 weeks. and i had a lot of pain when i applied after shave, then i relized that i had pain were i had acne, and i realized that i had quite a lot, so if you a 18 year old, make sure you don't have a lot of acne when you straight shave
