Abstract
BACKGROUND/ PURPOSE: Various studies have examined the properties of male skin. However, because these studies mostly involved simple measurement with non-invasive devices, a lack of understanding of the properties of male skin remains. METHODS: In this study, we focused and investigated not only on simple instrumental measurements but also on gender differences and men's subjective perceptions of skin and daily skin care habits. RESULTS: Barrier function depends on corneocyte maturation level as well as sebum amount. Irrespective of the skin type, a high percentage of male subjects perceived a 'tacky feeling'. However, the percentage of men perceiving a 'shiny feeling' differed by skin type. Furthermore, there was a relationship between skin care habits and skin function. Men who did not perform a daily skincare regimen demonstrated a significantly higher sebum amount and transepidermal water loss value than those who did perform a daily skincare regimen. CONCLUSION: The results of this study indicate that male skin has two specific characteristics: impaired barrier function because of the excess amount of sebum and a lack of an appropriate skin care regimen because of the 'tacky feeling' caused by excess sebum.
