A simple aftershave lotion with aloe vera helps. You may also be using a shave cream or soap that is an irritant to your skin as microabrasions cut your skin along with the cut hairs. Use a mild, mild soap as a shave cream, such as Dove with moisturizer or very mild such as Dial bar soap, or try using a lather made from a natural soap milk soap or olive oil soap bar found at Dollar stores (they have some nice specialty bar soaps at Dollar Tree if you look.) A good naturally-made soap, lathered well, used for shaving, will reduce the bumps. And afterwards, use a simple aloe vera gel, as plain as possible with very little added perfume, to heal the skin. I hope this helps!
