Modern sunscreens are very effective in protecting against sunburn and other damages caused by UV rays. Proper application plus following some easy guidelines puts you on the safe side.

Our tips – The to-do list for a comprehensive sun protection approach. (The order does not indicate importance) 

High Noon
Avoid being outdoors too long during the midday sun while on vacation. The sun is the strongest when it reaches its peak. Take a siesta and recharge your batteries. Use the UV index to know the expected values and the actual intensity of the current UV radiation. The Shadow Rule can also help you keep your skin safe: when the person’s shadow is long, the intensity of the UV rays is less. If the person’s shadow is shorter than the person is tall, the sun is stronger. This tip can be especially useful for children to indicate when the sun is very intense during the day. However, this doesn’t take into account other factors, such as how cloudy it is or the sun’s reflection on certain surfaces.

Find shade, don’t cast a shadow
Find shade and use it. Although shade is not entirely UV-free, UV radiation is less intense by as much as 50%. Because radiation is scattered, even in the shade, almost half of the UV radiation is still around. However, it should be taken into account that the strength of the reflection depends on the surface in question. The reflected portion of UV radiation is generally between 3–15%. However, snow can reflect up to 80–90% of UV rays. (Ref.: „2018, Turner and Parsis. Ultraviolet Radiation Albedo and Reflectance in Review: The Influence to Ultraviolet Exposure in Occupational Settings.“)

Maintaining your perspective 
Open your eyes: Do not forget to protect your eyes. Always wear sunglasses to prevent cataracts and retinal damage. The eyes should be completely covered by the glasses and a brown or gray tint is ideal. Sunglasses with good protection are labeled with "UV-400", "100 percent UV" or have the "CE" mark.

Check out the Sun Protection Factor 
The sun protection factor (SPF) of a sunscreen indicates how well it protects from sunburn. The maximum time spent in the sun is calculated by multiplying the length of time it takes to suffer a burn without sunscreen with the sun protection factor.Your skin’s natural sun protection refers to the time you can spend in the sun unprotected before you get sunburned. Depending on a person’s skin type, this can vary greatly. Remember, that sun protection is reduced when swimming, sweating and if sunscreen rubs off on towels and clothing.
