We assess that "Piz Buin - Moisturising Sun Lotion SPF 50+" can provide reliable sun protection based on the ingredient list. 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).

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).

The UV filters in this sunscreen are: tinosorb s 2.50% - 3.10%, avobenzone 3.10% - 3.80%, octisalate 3.50% - 4.30% and octocrylene 5.80% - 7.10%.

Irritation risk

Sun protection

This product offers a good level of protection against both UVB and UVA rays.

A weak sunscreen that protects against the sun rays that cause sunburn (UVB) and is somewhat effective against the UVA rays. It is quite stable and can help stabilize other, more vulnerable, sunscreen ingredients like Avobenzone. It is an organic, or so called "chemical" sunscreen

Anti-aging
