Sun filters

Inside Our Products

What are sun filters? 

Sun filters are essential ingredients that protect the skin from sun damage and prevent the risks of skin cancer such as melanoma as well as sunburn, premature aging of the skin, or the appearance of spots.
Organic filters absorb UVA and UVB rays, while mineral filters reflect mainly UVB radiation and less UVA radiation. 
Each sun filter provides a specific type of protection, which is why sunscreen products or daily photo-protection products (day cream with SPF) are usually composed of a combination of filters to ensure the broadest protection.

To identify sun filters in our products, take a look at the ingredients list on packaging. They can be found under the names "drometrizol trisiloxane = Mexoryl XL", "octocrylene", bis-ethylhexyloxyphenol methoxyphenyl triazine = Tinosorb S" (organic filters), "titanium dioxide", "zinc oxide" (mineral filters).

Where do they come from?

Sun filters consist of mineral compounds (originating from rocks and which reflect UV rays) or transformed organic compounds (originating from carbon and which absorb UV rays)

What are they used for?

Sun filters are ingredients used in sunscreen and skincare products to protect the skin from sun damage. Sunscreens prevent the risk of skin cancer by protecting the skin from UVA and UVB rays. They protect against skin reactions and sunburns. They protect the skin from premature ageing by preventing UVA rays from penetrating deeper into the skin.

What are they questioned?

Certain organic filters are accused of causing allergies, while others are pointed out as being endocrine disruptors. Mineral filters - when in nanometric form - are suspected of crossing biological barriers like the skin or mucous membranes, and spreading into the body, causing certain types of cancer. Lastly, sun filters are said to impact the environment and in particular coral reefs.


Why and how do we use them?

We use sun filters only in products where they are required to protect the skin from sun damage (skin cancer, sunburn, premature aging of the skin, appearance of spots).

A regular application of sunscreen helps maintain the protective effects on skin. We develop various products and textures (sprays, mists...), encouraging consumers to use sunscreen and reapply them as often as necessary.

We always choose a combination and quantity of filters that provide both an optimal level of protection and tolerance, coupled with a minimal environmental impact.

All of our products undergo a strict evaluation of their quality and safety for humans as well as for the environment before they are placed on the market. This is a fundamental principle that we apply everywhere our products are sold.

For more than 20 years, our environmental research laboratory has been working to understand and always improve the impact of our sunscreen products on the aquatic environment. 

To benefit from the latest scientific advances, we collaborate with research teams of excellence such as the Monaco Scientific Centerthe Criobe and the Tara Foundation. In fact, the Monaco Scientific Center and L’Oréal Research & Innovation have just published their findings on the absence of harmful effects of UV filters used in cosmetics on the photosynthetic activity of corals.
