The Australian research group took a closer look at sunscreen and collaborated with Cancer Council Victoria and the Australian Radiation Protection and Nuclear Safety Authority on their study. Sunscreen loss was determined at three different wind speeds and five different products. Results:

Quiet: 0 km / h One bottle is enough for about 2.5 times
Light breeze: 10 km/h About 54% of sunscreen loss
Moderate winds: 20 km / h About 70% of sunscreen

To test the spray products and their use in windy conditions, the researchers used a calibrated fan and a wind speed measuring device. It turns out that in windy conditions, more sun protection ends up in the atmosphere than in the body.

The average wind speed on Sylt in the summer months from June to August is high about 21.6 km / h. Then 70 percent of the sunscreen spray applied can be expected to be lost. With one of the products tested, 93 percent of that wind power was blown away.

The study shows: That’s how much sunscreen we should be applying

For good protection despite such high loss rates, a lot of content is required. Based on the five test products in the study, the following guideline values ​​can be established: If there is no wind, one spray bottle (175 grams) is only enough for about 2.5 full-body applications. With loss of protection in fair winds, you need more than one bottle, sometimes more than two bottles for a single application. Initial practical impression of the shape of the spray is not clear. More protection with significantly less content – According to the results, a good sunscreen turns out to be a better alternative. So no produce toxinsPay attention to the expiration date.
