Demo article: products mentioned here are fictional and shown for demonstration only.

Daily sunscreen is the single step that keeps the rest of your routine worth doing: it helps prevent sunburn and helps keep dark spots from looking darker.

How much?

About two finger lengths for the face and neck, or a quarter teaspoon. Most people apply half of that, which gives much less protection than the label says.

When to reapply

At least every two hours outdoors, and after swimming, sweating or towel drying. On office days, reapply before going out at lunchtime.

Mineral or chemical filters?

Mineral filters (zinc oxide, titanium dioxide) sit on the surface and are often preferred by sensitive skin. Modern mineral formulas blend in far better than they used to. The best sunscreen is the one you like enough to wear every day.

Sunscreen is one part of sun protection

Shade, hats and sunglasses matter too, especially between 10 a.m. and 4 p.m.
