| Dermis/epidermis ratio | 0.186 ± 0.04 | 0.17 ± 0.038 | 0.16 ± 0.04 | 0.356 ± 0.08 | 0.127 ± 0.03 | 0.18 ± 0.025 | 0.21 ± 0.03 |
The mean densitometric values in the papillary and reticular layers of the dermis in various, blindly selected areas. These data confirm that epidermal Cu, Zn-SOD expression is higher than in the dermis.
