Do not shave over the pimples as it can irritate the skin causing more breakouts. If you can avoid shaving over your acne with hair, it is best to be gentle and light. Never try to shave off the acne, as it will only make things worse. Do not press too hard on the shaver. It is recommended to use an electric shaver rather than a razor blade to minimize skin irritation. If that is also not possible, it is best to use a disposable razor. Make sure the razorblade is always clean and sharp. If not needed, it is best to shave once in 2 -3 days for acne with hair.
