Product summary

We believe that "Laboratoires de Biarritz - Organic Alga Maris Sunscreen Lotion Face and Body SPF30" 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).

It also works as a moisturizer, so you do not have to use an additional hydrating product. This product prevents early signs of aging by protecting against sun damage (all broad spectrum sunscreens do that).

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

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 moisturizer to be medium. For a detailed overview of all potential irritants: click here

Sun protection

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.
