What do we always mean when we talk about whitening?! When you talk about the whitening effect or white film when talking about sunscreen, you mean the white or whitish shimmering layer that lies on the skin. The white film usually occurs with sun creams that use mineral (physical) UV filters.
You can find out why you should not only avoid chemical UV filters for the sake of yourself but also for the sake of the environment in our blog article "What does sunscreen actually have to do with corals?"
Mineral UV filters work like a mirror on your skin. The tiny particles such as titanium dioxide and zinc oxide in the sunscreen settle on your skin and reflect the sun's rays, which are harmful to the skin. A bonus compared to chemical UV filter sunscreens: a mineral sunscreen protects you directly, as it does not have to be absorbed in order to be effective.

Our Naseweiss also works with mineral UV filters, but hardly whitens. To achieve good sun protection, you should apply a generous layer. You can then rub it on your skin. A barely noticeable white film remains. A slightly whiter residue can only remain on very hairy parts of the body, as cream often accumulates on the hair.
