How can you be sure skincare products are really safe?

When choosing your skincare today, you need a brand worthy of your trust. You also need full information on products to allow you to make the best choices.

At La Roche-Posay, we are committed to creating products safe for even the most fragile and vulnerable skin types. Read on to discover how we make sure our products are safe.

Laboratory testing on reconstructed skin


We run extensive tests on all our products before they come to market. Our Research & Innovation teams have developed a pioneering method, which means we avoid the need for animal testing. How does it work? We use a type of reconstructed skin called EpiSkin*. Only when we are satisfied with the test results on EpiSkin* do we move onto human testing. As well as providing innovative technology for incredibly precise testing - and a viable alternative to animal testing - this allows us to exclude any irritants at the earliest testing stages.

Clinical testing on the most vulnerable skin types

Then come clinical tests on the products’ target populations carried out under the supervision of a dermatologist. As the sensitive skin specialist, La Roche-Posay takes the “tested on sensitive skin” claim very seriously. We set up genuine clinical tests where all of the participants have sensitive, atopy-prone or allergic-prone skin in line with the product being tested. We also conduct studies to ensure safety on the most fragile skin and on patients undergoing cancer treatments to provide optimum skin relief with the highest tolerance.

Patch testing

To test our products’ hypoallergenicity, we make use of a technique called repeated patch testing**

The La Roche-Posay rule: 100% allergy-tested

We scrupulously test each formula before launching it on the market. Some of our products have been applied more than 10,000 times before making an appearance on your bathroom shelf! If a single participant develops an allergic reaction during testing, due diligence takes us straight back to the labs to revise the formulation.

Continuous checking even after the product hits the shelves

We have a Cosmetovigilance program whereby we systematically monitor all of our products’ tolerance post-launch to confirm their excellent tolerance. This involves the recording and in-depth investigation of all adverse events reported by consumers and/or doctors. We actively participate in resolving each case and take any and all corrective actions with regard to the product in question and its ingredients. Some of our products are now more than 20 years old and are still making people’s lives better every day.

* EpiSkin consists of small discs of laboratory-synthesized human skin. Healthy human skin cells (keratinocytes) are grown in petri dishes. EpiSkin is a healthy structure on which to test cosmetics and therefore avoid animal testing.
** The product is applied under an occlusive (air- and watertight) patch. The skin is examined by a dermatologist after removing the patch. This process is repeated several times. The skin is then left to rest for 2 weeks. A further patch test is then carried out as a re-challenge test.
Once again, the skin is examined by a dermatologist at 30 minutes, 24hrs and 48hrs.
This allows us to confirm that the tester has not developed an allergy to the product.
