The Studies Performed on
Our Suncare

nos études solaires

At Laboratoires de Biarritz, our R&D strategy is driven by three fundamental values:

• Creating safe, high-performance cosmetics that take care of you and that you can trust,

• A commitment to minimize the impact of our skincare on the environment,

• Providing scientific proof for all our claims.

Our Suncare line is a perfectly illustration of these three principles

When you were born by the ocean, when you interact with it and draw inspiration from it every day, it inevitably makes you design your cosmetics a bit differently. Making our environmental impact as minimal as possible is a clear imperative.

Beyond a rigorous selection of non-controversial ingredients, our formulas are subjected to multiple ecotoxicity tests by specialized, independent laboratories.

A Carefully Selected Combination of Filters

Our organic dermo-suncare range, designed for sensitive skin, is formulated with mineral filters that offer high tolerability, particularly for delicate or compromised skin. They form a protective layer on the skin's surface, providing immediate protection from the moment they are applied.

Our range of sensorial Suncare products is elaborated, in part, using synthetic filters to ensure invisible formulas. We scrupulously chosen for their safety. Not all synthetic filters are equal when it comes to safety. Some filters are today the subject of controversy, such as octocrylene, oxybenzone and octinoxate, due to concerns over their potential irritancy, their suspected endocrine-disrupting effects, and their environmental impact. They are therefore excluded from our formulations.
At Laboratoires de Biarritz, we use the latest generation of synthetic filters, and more broadly, filters recognized for their performance and well-established safety profile. With deep expertise in photoprotection, our R&D team maintains a rigorous approach to selecting the best UV filters, combining broad-spectrum protective efficacy, safe use and minimal impact on marine ecosystems.

Highly Natural Contents

True to our convictions and scientific charter, our R&D pushes the formulation of our Suncare products towards the highest possible levels of naturalness.

In our Organic dermatological Suncare, protection is provided by mineral filters of natural origin. These formulations thereby achieve 99.6% to 100% natural-origin ingredients.

In our sensorial suncare products, photoprotection is provided by synthetic filters, which by definition are not of natural origin. Still, our commitment to excellence drives us to achieve the highest possible percentage of natural-origin ingredients.
For example, our Sun Oil SPF30 contains 84% natural-origin ingredients and our Sun Milk SPF50 76%.

Beyond these high proportions of natural-origin ingredients, all of our Suncare products include a significant percentage of ingredients from Organic Farming. The formulas contain between 20% and 33% organic ingredients, including in our sensorial Suncare products — making us stand out from the rest of the market.

Increasingly Rigorous Ecotoxicity Testing

To provide the strongest possible guarantees for our planet, it seemed crucial to assess the impact of our Suncare on aquatic ecosystems scientifically. So we evaluated their biodegradability¹ and had ecotoxicity testing performed using extreme conditions². We did this both in seawater, to know the impact on the oceans, but also in freshwater. Indeed, our products also end up in the water of your shower.
A further requirement that our R&D team sets itself is to evaluate our formulations in their entirety, that is, to conduct tests on the finished product, the ones that actually come into contact with the environment. This more demanding approach enables a more representative assessment of potential impact, in keeping with our environmental responsibility ethos, at a time when evaluations are often limited to certain ingredients tested in isolation.
To get a complete overview, our studies used a wide array of different organisms: seven planktonic and sedimentary organisms from both fresh- and saltwater, representative of various levels of aquatic food chains.
The results show that, under the conditions tested, our formulas present no impact on aquatic ecosystems, reflecting our commitment to developing the most environmentally-friendly products possible.


¹ Standard method for freshwater (OCDE301F).
² For marine environments: crustaceans - Artemia salina (method FD ISO 14669); marine algae - Phaeodactylum tricornutum (method EN ISO 10253), corals (non-standardized method/study of nub bleaching and polyp retraction), sedimentary crustacean -  Corophium (method NF EN ISO 16712), bacteria - Vibrio fischeri (method NF EN ISO 11348-3). For freshwater environments: water fleas - Daphnia magna (method NF EN ISO 6341), on freshwater algae - Pseudokirchneriella subcapitata (method NF EN ISO 8692).

Ocean Engagement***

When we put this logo on the packaging of our Suncare, it is to display our commitment to reducing the impact of our formulas on marine biodiversity. Our numerous ecotoxicity studies demonstrate this engagement.
