Sun protection for the backs of your hands

In short

Yes, the backs of your hands need sun protection, because they are almost always uncovered in the sun and sunscreen disappears from them faster than anywhere else. On the steering wheel, on the bike, on a walk and in the garden, your hands are on top. When you apply sunscreen to your face, some cream stays on your palms but hardly any gets onto the backs of your hands. And every hand wash and every towel removes the protection again. So for your hands: apply sunscreen deliberately and reapply after every wash.

Why hands in particular get forgotten

Three things come together. First, position: like the face and neck, the hands are among the body parts that are least often covered all year round. Second, technique: when you apply sunscreen with your hands, you spread it with your palms; the backs of your hands only get whatever happens to be left over. Third, everyday life: hands are washed, dried and wiped on trousers. The German Federal Office for Radiation Protection (BfS) points out that washing or rubbing off reduces the amount of sunscreen on the skin and thus lowers the sun protection factor; it recommends reapplying at least every two hours and especially after bathing and drying off (BfS, UV-Schutz durch Sonnencreme).

How little cream people usually apply is described in the European Commission's recommendation on sunscreen products: the stated sun protection factor applies to 2 mg of product per square centimetre of skin; if only half that amount is applied, the protection can drop by two thirds (Recommendation 2006/647/EC). On the backs of the hands, where people tend to spread thinly, it is especially easy to fall short.

Car, bike, garden: where hands catch the sun

SituationWhat UV gets throughWhat helps
Driving, windows closedUVB is blocked by all windows; depending on the glass, UVA passes through the side windowson long sunny drives, apply sunscreen to the backs of your hands, use the sun visor

Garden, manual worksun plus frequent hand washinggloves, reapply after washing
Water, snow, mountainsadditional reflection, higher radiationvery high protection, reapply often

On cars in detail: the BfS writes that all windows in a car block UVB and the windscreen also protects against UVA, while UVA can pass through the side windows to a greater or lesser extent (BfS, UV-Schutz im Auto?). In a measurement of 29 cars, the windscreen blocked on average 96% of UVA radiation and the side window only 71%, with a range of 44 to 96% (Boxer Wachler 2016). In a study from Tübingen, the arms of test dummies received 3 to 4% of the ambient radiation with the windows closed, 25 to 31% with the windows open and 62% in an open convertible (Moehrle et al. 2003). If you drive a lot for work, you have a reason to protect the backs of your hands, above all with the window open and through the side window.

How to apply sunscreen to the backs of your hands

  1. In good time: the BfS recommends applying sunscreen 20 to 30 minutes before going out in the sun (BfS).
  2. Deliberately: put the cream on the back of one hand and rub the backs of your hands together. Then fingers, the spaces between them, knuckles and wrists.
  3. Enough: better a little too much than too little. Why the amount matters so much is explained in SPF, UVA protection and water resistance.
  4. Reapply: after every hand wash, after drying off and after swimming, otherwise at least every two hours. Even water-resistant sunscreen is removed by soap and towels.
  5. In the evening: wash your hands and apply a normal hand cream. It cares for your skin but does not protect against UV.

Hand cream with SPF or sunscreen?

A hand cream without a sun protection factor does not protect against UV radiation, even if it leaves a film on the skin. Hand creams with SPF exist, but they are only as good as the amount applied and how often you reapply. For a day outdoors, a proper sunscreen is usually the simpler choice, because it is designed for high protection and you have it with you for your face and arms anyway.

According to the EU recommendation, sunscreen products should protect against both UVB and UVA; the sun protection factor itself only describes protection against the radiation that causes skin reddening, which is mainly UVB. The recommendation also states that scientific findings allow the conclusion that sunscreen products can protect against damage from premature, light-induced skin ageing (Recommendation 2006/647/EC). If you notice spots on your hands that are new or changing, have them looked at by a dermatologist. A cream is no substitute for that.

Mineral filters such as zinc oxide and titanium dioxide sit on the skin; how they cover UVA and UVB is explained in Zinc oxide or titanium dioxide, and particle size in Nano or non-nano. That mineral sunscreen can look white, especially on the backs of the hands, is described in the blog post White cast from sunscreen.

Frequently asked questions

Do my hands need sun protection in winter?
Usually not in everyday life, but yes in the mountains and on snow. There your hands are often covered by gloves, but not during breaks without them.

Is sunscreen in the morning enough for the whole day?
Not on your hands. Every hand wash removes some of it. Reapplying after washing is the most important step.

Does the car window protect my hands?
Against UVB, yes; against UVA, mainly the windscreen. Depending on the glass, some UVA radiation comes through the side windows, and much more with the window open.

Are gloves better than sunscreen?
According to the BfS, clothing is the simplest protection. Gloves are practical for cycling and gardening; where you do not want to wear them, sunscreen helps.

Can I mix sunscreen and hand cream?
Better not. That dilutes the sun protection. Sunscreen during the day, hand cream in the evening.
