Both types of UV–radiation play a role in the development of skin cancer in the long-term . Therefore, proper sun protection is necessary. Not only when you go out sunbathing, but also if you stay outside longer on a sunny day.

Precautions:

Lubricate your skin generously half an hour before going into the sun. This contributes to the protection.
Apply regularly, especially after swimming, sweating or towelling.
Choose a SPF that suits your skin type. When in doubt, choose a higher factor instead of low!
Avoid the sun during the hottest part of the day (between 12:00h and 15:00h).
Keep babies and young children out of direct sunlight and use sunprotection with a high SPF.
Do not stay too long in the sun, even if you use sunprotection.
