Here's what dermatological testing covers, and just as importantly, what it doesn't.

This is what "dermatologically tested" refers to. A group of volunteers uses the product under the supervision of a dermatologist, who checks whether it causes any irritation on the skin.

It's a tolerance test. It confirms the product is well tolerated, not that it produces a particular result. Only some of our products carry this claim, so check the product page before you use it.

Some statements about a product's effect on the skin come from use tests. Here, people use the product for a set period under a dermatologist's supervision, and the dermatologist forms conclusions based on the users' experience over that time. These rest on real-world use rather than lab instruments.

Instrumental tests use specialized technology to measure things on the skin directly, like the depth of wrinkles, moisture levels, pigmentation, and overall skin condition. These give measured, quantified readings rather than subjective feedback.

Dermatological testing checks how well skin tolerates a product. It does not prove that a product is effective. "Dermatologically tested" and "clinically proven" are not the same thing, and they shouldn't be used interchangeably.

You can describe a product as dermatologically tested only if that specific product carries the claim. If you're unsure whether a product qualifies, check the product page or ask our support team.
