A man's skin is approximately 20% thicker than a woman's, and is typically firmer because it's richer in collagen and elastin. However, because of more active sebaceous glands, men's skin tends to be much oilier. It is also more prone to dehydration because of daily or regular shaving. Men are also more likely to develop skin cancer than women. Products which are specially formulated taking into consideration these specific needs work best for men.
