Yup, just a sign that your technique is still improving. Your shaves are good enough to not have visible irritation, but you're still causing a bit of trauma to your skin.
Nothing to do for it but to keep working at your shave, it'll get better over time.
working too hard?? not on yer life! anyone who works hard enough to sweat and gets paid for it is lucky Lately, in order to not experience so much burn, my goal is a sas on most week days.
Yep, it's you. I get it sometime too, yet when I know my lather and shave was exceptionally good (for me ), I don't get any sweat sting even working out. And nine out of ten times, it's my neck that's the damaged goods.
