"Measure sunscreen with a spoon"

We all look forward to spring, light and warmth, the first rays of sunshine. You should not forget your skin and even now think about the sunscreen. Many of my patients believe that it is not necessary until midsummer. In fact, the UV rays have a lot of power already in the spring. Redness or even sunburn should be avoided at all costs. Sunlight promotes skin aging. Much worse, it can trigger the development of skin cancer.

"How much cream should I take?", I am often asked, and: "Which SPF is necessary?" Basically, one can say that there is not too much. I recommend a sun protection factor of 30 to 50+, depending on skin type and type of sun exposure. The guideline values ​​set by medical societies are two milligrams per square centimeter of skin area. How do you measure that? If you have a teaspoon at hand, no problem: 1 tsp sunscreen (about 5 g) is enough for the face. For the entire body you need about 30 grams of sunscreen. That's a good handful.

Rub cream or lotion well and let it soak for a long time. It is recommended to cream for about 30 minutes before getting into the sun. Particularly important are the "sun terraces" nose, lips and ears. Incidentally, the earlobes are often forgotten! The back deserves special attention as well. My colleagues from the University of Vienna recently published a groundbreaking study.

The new finding: Sun-related changes on the back, such as freckles, wrinkles and age spots, are even more important as a risk factor for skin cancer than a light skin type or reddish hair color. Maybe that's because we do not constantly expose our backs to the sun. If he then gets unfamiliar UV light, he is more in danger. Probably the back is rather neglected, because you can cream him bad himself.

And one more request: Get the doctor to check for signs of skin cancer on a regular basis. Skin cancer screening is reimbursed every two years by the statutory health insurance funds. As with all cancers, the sooner dangerous changes are detected, the better the chances of recovery.

Take the test: Which sunscreen is the right one?
