What role does CYP1A2 play in skin aging?

The provided context does not contain specific information about CYP1A2's role in skin aging. In general, CYP1A2 is a phase I detoxification enzyme that metabolizes estrogens and polycyclic aromatic hydrocarbons (PAHs) from pollution and tobacco smoke. These substances can promote oxidative stress and collagen degradation, potentially contributing to skin aging. However, direct evidence for a significant role of CYP1A2 variants in human skin aging is limited and mostly based on mechanistic studies. Some research suggests associations between CYP1A2 polymorphisms and susceptibility to UV-induced skin damage, but the data are insufficient for personalized recommendations. Caveat: The predictive value of single genetic tests for skin aging is low; lifestyle factors such as sun protection and diet have a much greater impact.
