What are the precautions for using razors

1. Never shave before bathing. The skin is unprepared for this, and you're likely to experience a burning sensation after shaving and cause ingrown beards.
2. Don't shave before playing sports. Because sweat can irritate the skin you just shaved, creating an infection.
3. Do not shave off the hair. Although shaving pellets will result in a cleaner shave, they can easily irritate the skin and form barbs.
4. Don't borrow razors from others, and don't lend your own to others. Contaminated blades can cause serious skin diseases.
5. When shaving your face with the blade, don't strain your facial muscles too much. This makes it easy to shave off the fibrous roots on the surface of the skin.
6. Do not shave the same spot from different directions. You risk shaving your beard too short to create barbs.
7. Do not use blades that are too old or even rusted. When the blade is not sharp enough, it should be replaced in time.
8. When shaving with a razor, do not do it on dry beards. Those scraped knife marks and bloody pustules will take at least three or four days to heal if you don't keep your beard moist.
9. Post-shave moisturizer is medically unnecessary. While the ingredients do make shaved skin look more radiant, and while you'd love to have a scent after shaving, it's advisable not to use perfumes with ethanol and witch hazel tinctures, which can lead to infection. Check out the ingredients in your after-shave moisturizer, and see if they're meant for after-shave.
