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

It is a mineral sunscreen. In other words, it contains non-organic UV filters. It will probably not sting your eyes but might leave a white cast.

This product can be considered "reef safe" because it does not contain the UV filters (oxybenzone and octinoxate) that can be harmful to coral reefs when present in the water in high concentrations.

Product summary

Based on the ingredients included, we believe that "Laboratoires de Biarritz - Organic Alga Maris Sunscreen Lotion Face and Body SPF50" can offer reliable sun protection. 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).

Because it includes good moisturizing ingredients, it can also work as a hydrating day cream. Like all broad-spectrum sunscreens, this product helps prevent early signs of aging.

Sunscreen filters

This moisturizer is a mineral sunscreen. It uses titanium dioxide and zinc oxide for sun protection. Both titanium dioxide and zinc oxide almost never irritate even the most sensitive skin and eyes, but can leave a white cast.

Irritation risk

This product does not contain known common irritants and is suitable for sensitive skin. We assess the overall irritancy of this moisturizer to be low. For a detailed overview of all potential irritants: click here
