I am searching for a good disposable razor to use when I don't have time to DE shave, which is most days. I used the Schick ST2 when i first started shaving and never got any razor burn. I have very light facial hair on my cheeks and mild hair on my chin and upper lip. Do you guys think I'd still have success with the ST2 now and achieve a shave with no irritation? Please note that I have very sensitive skin.
