Three checks for an everyday routine: amount, coverage, and reapplication. Save the full checklist or choose a reminder below. No account needed.
Use sunscreen generously, following its label. Finger-lengths are a visual cue, not a guaranteed measurement, and bottle lifespan does not tell you your protection level. Read the full amount and reapplication guide for adult amounts, product differences, and the limits of shortcuts.
