All skin types become irritated from shaving, especially the upper layer of the skin. Even with a healthy and smooth skin the razor blade cuts not only the beard, but also the uneven places on the skin and destroys thus its wholeness. Minor injuries incur as well as scabs and pimples. To limit such phenomena, you should always use a very sharp razor blade, avoid cutting the beard repeatedly at a same place and apply an aftershave of good quality afterwards.
