Based on the ingredient list, we assess that "Piz Buin - Mountain Sun Cream - Very High SPF50+" can provide reliable sun protection. We love that it can protect from both UVA and UVB rays (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).
As a plus, this sunscreen uses some of the new generation UV filters (Tinosorb M). These filters are more stable and more gentle on the skin.
It should also be hydrating enough to use without an additional moisturizer during the day. Like all broad-spectrum sunscreens, this product helps prevent early signs of 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. The UV filters in this sunscreen are: tinosorb s 0.45% - 0.70%, avobenzone 1.60% - 1.90%, uvinul a plus 0.45% - 0.70%, octisalate 4.70% - 5.80%, tinosorb m 0.75% - 1.10% and octocrylene 3.70% - 4.50%.
Irritation risk
This formulation includes some common irritants, including ingredients that do not provide a benefit for the skin. We assess the overall irritancy of this product to be medium. For a detailed overview of all potential irritants: click here

Moisturizing
What does the product description say?
This product contains good ingredients to attract water to the upper layer of the skin. These ingredients are called
"humectants":
glycerin, trehalose.
When humectants are on the surface of the skin, they “pull in” the moisture from the outside environment, or from
within deeper layers of the skin. If the air is dry, humectants can speed up the moisture loss from the skin. This
is why it is a good idea to use another product on top of this one to help "seal in" the moisture (look for
ingredients like dimethicone, squalane, oils and butters).
