This all depends on how you use it.
If you're using an electric razor for a quick shave, you may need to learn how to apply it to your skin so that you don't irritate or damage skin.
If you're using a precision trimmer, learn how to apply the right amount of pressure and direction to get those delicate spots so that you get the job done without irritating your skin.
If you're finding that your skin gets noticeably irritated by each shave, you may also be allergic to the blade materials or other components. You may want to try a different razor, or contact a doctor to see if you may be allergic to certain metals or materials.
