“Natural ageing, also called intrinsic or chronological ageing, is the natural, genetically driven process of skin ageing, marked by gradual loss of collagen, elasticity and structural integrity over time,” explains Dr Nadal. Photoageing, on the other hand, results from external factors: “This is mainly sun exposure,” says Dr Nadal, “and it leads to premature skin damage like deep wrinkles, pigmentation and skin laxity.”
