Sun Care Below the Neck: The SPF Rules Everyone Skips

Everyone knows the face SPF rules. Below the neck, almost everyone breaks them:

The chest gets sun through car windows — UVA passes glass; the left-side chest and arm of drivers measurably age faster. Two finger-lengths per limb is the real dose — most people apply a quarter of it. Backs of hands — reapply after every wash or accept that morning SPF is gone by 10am. The part line and ears on beach days. "It's cloudy" isn't a strategy — up to 80% of UV passes through cloud.

And after sun: hydration repairs the barrier the day stressed. Sun care and after-sun care are one routine, not two.

The after-half: Butta Drop with panthenol.
