Do I need sunscreen every day, even indoors?

For most people in a sunny climate, the usual advice is to protect exposed skin on days when you are outdoors, and to do it daily if you are out a lot. The NHS and the American Academy of Dermatology both explain that sunscreen is one part of sun care, along with shade and clothing.

What is a simple rule?

1. Outdoors for more than a short time: use sunscreen on exposed skin, and cover up or find shade at midday.
2. Walking to the car or sitting by a sunny window: many people still apply it to the face and hands. Ask your pharmacist if it suits you.
3. Indoors all day, away from windows: you may not need it. Daily habits differ, so use your judgement.

Details such as SPF and UVA marks are in how to choose a sunscreen.

The exception

Babies, people with a history of skin problems, and people who use strong skin products or take some medicines may need different advice. Ask a doctor or pharmacist. Any mole or mark that changes needs a doctor. See should I get a mole checked.

A sunburn needs care too. See sunburn: what to do.

This is general information. Ask a licensed professional about your own skin.

What else counts as sun care?

Sunscreen is one layer. Shade at midday, long sleeves, a wide hat and sunglasses all help, and none of them replaces the others. Sunscreen also needs enough product and reapplying, as the label says. Windows can let some UV through, so a seat by a sunny window is not the same as being in the dark.

If your skin stings or reacts to a product, stop using it and ask a pharmacist. Try a different type only after a patch test.
