IMPORTANT

MySun provides model-based educational estimates—not medical advice, a diagnosis, a UV measurement or a guarantee against skin damage. Sunscreen does not make UV exposure risk-free. Follow local guidance and consult a qualified clinician for health concerns.

Some features require an optional Sun+ subscription.
