How Often Should You Reapply Sunscreen?

How often should you reapply sunscreen to your face?

When outdoors, you should reapply sunscreen to your face about every two hours. If you've been swimming, sweating heavily, or dried your face, you should reapply the sunscreen regardless of the time.

Do you also need to reapply sunscreen in the shade?

Yes, reapplying sunscreen is also advisable in the shade. Some UV radiation is reflected by water, sand, buildings, or other surfaces and still reaches the skin. If you spend extended periods outdoors, you should therefore reapply your sunscreen regularly.

How long does SPF 50 sunscreen last on your skin?

An SPF of 50 does not protect the skin all day. Sunscreen is gradually removed by sweating, friction, or water. Therefore, experts recommend reapplying sunscreen approximately every two hours, as well as after swimming or towel drying.

Do I always have to reapply lotion after swimming?

Yes, even waterproof sunscreen should be reapplied after swimming. Water, friction, and drying with a towel can compromise the protective film and reduce UV protection.

Can you use too much sunscreen?

No, generally not. Many people even apply too little sunscreen, which means the stated SPF is not fully achieved. A generous amount ensures reliable UV protection.

How often should you apply sunscreen in everyday life?

For everyday use, it's usually enough to apply sunscreen generously in the morning. However, if you spend several hours outdoors or are directly exposed to the sun, you should reapply sunscreen approximately every two hours – especially on your face and other exposed skin areas.

Sunscreen is one of the absolute summer essentials to protect your skin from UV radiation. After all, this can promote skin aging and lead to serious damage. To ensure your skin is properly protected all day long, you should reapply sunscreen regularly. But how often should you reapply it? You'll find out that and more here!

How Often Should You Reapply Sunscreen?

Especially if you sweat, go swimming, or have dried yourself off, you should reapply sunscreen. Even water-resistant products are no longer effective then.

In general, you should reapply sunscreen every two hours to maintain protection. Reapplying does not extend the protection, but only maintains it!

Why Do You Need to Reapply Sunscreen?

Especially in summer, when you sweat a lot, exercise outdoors, or go swimming, sun protection is reduced. To keep your skin protected, you should reapply sunscreen immediately afterward or every two hours.

However, reapplying does not extend the protective effect each time – the duration you can stay in the sun with UV protection remains the same.

Does Reapplying Extend Sun Protection?

No, sun protection is not extended by reapplying. The protection merely remains intact. How high your protection is depends not only on the SPF of your sunscreen but also on your skin's natural protection.

Sunscreen is dispensed from a tube onto a hand outdoors – ready to be applied to the skin.

Depending on your skin type, your natural protection time is higher or lower, so you can stay in the sun longer or shorter with sun protection. If you multiply the SPF you use by your natural protection time, you get the maximum duration you should stay in the sun – to avoid risking sunburn and other skin damage.

How Much Sunscreen Should You Use When Reapplying?

According to the Federal Office for Radiation Protection (BfS), adults should use four heaped tablespoons of sunscreen for the body to achieve the stated SPF. For the face, you should apply two finger-lengths of the product.

Even when reapplying, you should use this amount of sunscreen to ensure protection.

Reapplying Sunscreen Over Makeup – Is That Possible?

You should definitely apply sunscreen before your makeup to protect your skin from UV radiation. It's best to wait a few minutes between the two layers so that the sunscreen can properly absorb into your skin and the texture doesn't pill.

Light sun sprays are suitable for reapplying, as are tinted formulas that you can gently apply to your face with a makeup sponge. Ideally, on such sunny days, you should avoid powder makeup so that the textures harmonize well together.

Common Mistakes When Reapplying Sunscreen

too little product: Make sure to use about four heaped tablespoons of product for the body and two finger-lengths for the face. Only then is the SPF guaranteed.
reapplying too rarely: After sweating, swimming, or drying off, but at the latest after two hours, you should reapply sunscreen.
underestimating the sun: Even if it's cloudy or even in winter: You should use sunscreen every day.
forgetting other UV protection measures: Nevertheless, it's best to stay in the shade and especially protect your head with a hat or cap to prevent sunburn on the scalp or sunstroke.
