The natural oil and moisture level drops, the muscle tone is decreased, blood circulation becomes poor. All these lead to a dry, wrinkled and shallow skin. Decrease in metabolic rate gives a puffy look due to accumulation of metabolites.

The description clearly matches mature/aging skin characteristics: decreased oil and moisture, reduced muscle tone, poor circulation leading to dryness and wrinkles, and metabolic slowdown causing puffiness from metabolite accumulation. This is not 'Normal' skin (which would have balanced oil/moisture), not simply 'Dry' skin (a temporary condition), and not 'Natural' skin (too vague).
