Why You Need SPF Every Single Day
If you only ever adopt one skincare habit, make it this one. Up to 80% of visible facial aging is attributable to UV exposure — and it accumulates on cloudy days, in cars, and through windows.
UVA is the quiet one
UVB burns; UVA ages. UVA penetrates glass and cloud cover at nearly full strength all year round, silently breaking down collagen and triggering pigment. That's why 'I'm indoors most of the day' isn't the loophole it sounds like.
How much, how often
Two finger-lengths for face and neck, applied as the last step of your morning routine. Reapply every two hours of direct sun — for most office days, a morning application honestly covers you.
Make it effortless
The best SPF is the one you don't notice. A modern mineral formula with no white cast doubles as a smoothing primer, so it replaces a step instead of adding one. Keep it next to your toothbrush; pair the habits.
