Abstract
Shaving is one of the daily tasks for most men. However, shaving has caused damage to the skin in many cases. In this study, we observed the skin and beards of 21 men aged from 24 to 62 yr and investigated the influence on the skin and the performance of shaving using three models of electric shavers. As the result, it was found that subjects who have a thicker beard or subjects who take a longer time for shaving tend to have dry skin, rough skin and skin with pigmented spots. On comparison of the three models of electric shavers, one rotary shaver had few instances of TEWL and bleeding. The rotary shaver was the gentlest to the skin of the three models. The other two models were swing shavers. On sensory evaluation, “sharpness of the three models” and “a feeling of close shave” tended to have a linear relation with increase in TEWL and increase in redness. Then it was observed that it is easy to misunderstand the burden on skin with good shaving performance. As it was revealed that the rough skin of a man is mainly caused by shaving in this study, the importance of shaving and skin care to reduce the burden on the skin was shown.
