Skin Age Calculator

Estimate how your lifestyle habits โ€” sun exposure, sunscreen use, sleep, smoking, and hydration โ€” affect your skin's apparent age. Based on published dermatological research on photoageing and skin biology.

Lifestyle estimate, not a clinical measurement. Skin age is not a standardised medical metric. This calculator provides a directional lifestyle estimate based on published risk factor research. Only a qualified dermatologist can assess your actual skin age.

The science behind skin ageing

Skin ageing occurs through two main pathways: intrinsic ageing (driven by genetics and time) and extrinsic ageing (driven by environment and lifestyle). Research consistently shows that extrinsic factors โ€” especially UV exposure and smoking โ€” can add years to skin appearance beyond what genetics alone would produce.
