What role does CYP1A2 play in Haut?

The role of CYP1A2 in skin is not covered in the provided context. CYP1A2 is primarily a liver enzyme involved in caffeine and drug metabolism. Its expression in skin is low, and its function there is not well-established. Some mechanistic evidence suggests it may metabolize certain environmental toxins or hormones, but this is speculative. Consumer DNA tests typically include CYP1A2 for caffeine sensitivity, not skin health. Without direct skin-related studies, any claim about CYP1A2 and skin is weak. Skin health is far more dependent on sun protection, diet, and skincare than on this single gene variant.
