In one experiment, the team measured the wrinkles at the corner of the eyes, commonly known as crow’s feet, of Japanese men and women.

The results revealed that men had a larger volume of wrinkles and that they were likely more advanced in all age groups compared to women.

Men aged in their 30s all the way to their 50s, were found to have similar wrinkle distribution to women that were one generation older.

By calculating the age difference observed in this analysis, the researchers concluded that men form and develop wrinkles approximately 10.9 years earlier than women.

Using 3D analysis, the researchers were able to confirm that the wrinkles were also more likely to be deeper and larger in men than in women.

In another survey on men and women in their 20s and 30s, Shiseido found that men had lower antioxidant levels and higher microinflammation indexes compared to women.

Further investigation confirmed that men had higher amount of MMP9, an enzyme that degrades collagen and other substances in the dermis that are responsible for skin elasticity and firmness, compared to women.

According to Shiseido, MMP9 increases with skin damage, suggesting that it could be a reason that men have higher microinflammation indexes than women.

In another survey, Shiseido studied the skin elasticity and firmness in the deeper dermis layers of the cheeks on men and women in aged 20 to 60.

The results showed that men had lower indexes in all age groups, and the index was significantly lower for men in their 20s to 40s.
