[[* SUNSCREENS should be applied often and liberally to exposed skin. For UVA protection, look for ingredients like Mexoryl SX, titanium dioxide and an avobenzone that doesn’t degrade in light. For UVB, the American Academy of Dermatology recommends at least an SPF 15. Keep the following in mind, even in winter, and especially near water, snow and sand:
Use a shot glass full of lotion (or an ounce) on your body; two coats of spray since it’s hard to detect missed spots.
Apply a sunscreen 15 to 30 minutes before exposure, because some take time to become fully active.
Ultraviolet A rays can pass through window glass, so office workers with the luxury of a view should take precautions.
Reapply after swimming, toweling off, sweating or every two hours, if you miraculously don’t perspire at the beach.
A sunscreen’s SPF doesn’t correlate to how long it lasts. So even an SPF 85 or SPF 100+ needs to be diligently reapplied. *]]

(3) Useful to have UVA-fighting ingredients like an avobenzone that doesn’t degrade in light or Mexoryl SX. *]]
