Product summary

We believe that "Riemann - P20 Sun Protection Continuous Spray SPF50" can provide reliable sun protection based on the ingredients listed. It can protect from both UVA and UVB rays. This is great news because not all sunscreens with SPF ratings give UVA protection. (UVA rays do not cause sunburn, but still damage our skin and lead to early aging).

Sunscreen filters

This sunscreen uses so-called "chemical", or organic UV filters (organic simply means that their molecules contain atoms of carbon). These filters typically give good sun protection and rarely leave a white cast, but they can be irritating for sensitive skin. These are the sun protection ingredients in this sunscreen: uvinul a plus 5.00% - 7.50%, octinoxate 3.90% - 5.90% and octocrylene 8.60% - 12.90%.

Irritation risk

There are some common irritants in this product, including ingredients that do not have benefits for the skin. We assess the overall irritancy of this product to be medium. For a detailed overview of all potential irritants: click here
