Figure [1]: The sun protection factor of a
sunscreen is different in America and Europe.>

Michael Have you ever been to America, bought SPF 20 sunscreen, laid on the beach, and ended up with a patchy sunburn? Ha! That happened to us too. Obviously, it wasn't a "real" SPF 20.

Funnily enough, only speculative nonsense can be found on the internet about this topic. Some claim that the German sun protection factor (LSF) and the American sun protection factor (SPF) are determined using the same method. Others report drastic discrepancies, stating that the American value is exaggerated by 50% to 100%. There are no serious scientific reports -- the medical clowns of the world obviously haven't published their dissertations on the internet yet. Hello, wake up!

However, we are not naive either. Supported by long-term research projects on the world's most important beaches, we put on our white lab coats today and boldly claim: The "SPF" indicated on American sunscreen packages corresponds to a "sun protection factor" that is about 30% lower. So if you buy a 20 SPF in America, you effectively have a 12 SPF by German standards. I wouldn't lie on any Californian beach with that, as a sunburn is inevitable.

Recently, Costco had a deal on two tubes of Neutrogena sunscreen (see image 1) with SPF 55 (which is roughly equivalent to SPF 35 by German standards) for $13.99. A bargain price! Neutrogena makes one of the best sunscreens in the world. Not chalky at all, as is usually the case with sunscreens in the higher protection range. Silky on the skin and not greasy at all! I had to stock up immediately.
