Then learn to shave properly and buy better products, as you obviously need it.
Shaving is not the same as putting on foam and shave it off with a razor, well it is, but then you get the problems mentioned above.
1) Take a shower
2) Scrub your face and throat
3) Put on gel (foam isn't as good), oil, both or whatever and let it wear for 3 minutes.
4) Then shave with the root's direction, and only one way as the doing it up and then down leaves a smooth result, but also grown-in hair which causes a mess the day after
(so a good shave is not the one where you can stroke up and down with your fingers and feel only smooth skin.... like I said, awesome at the time but pain tomorrow!)
5) When finished, and this is the most important step for many, rinse with cold water.... because when your skin it hot and your pores are open it is also irritated after shaving so bacteria can easily get in and cause acne, more irritation, red marks and burns etc...... cold water... alfa omega =)
did you really just give me instruction on how to shave?
I do use good products, gillette - it's the best a man can get you know! my guess is that as i normally only use a trimmer my skin isn't used to the shave.
