Efficiency and quality testing (in-use / instrumental tests)

In-use tests are designed to determine the quality of a cosmetic product supporting producers claim.

Moreover, product claims need to be supported by robust evidence during product use.

Tests are carried out by several dozens of volunteers who test products during specified time and conditions. Our team of experts – dermatologist, ophthalmologist and/or gynecologist provide supervision of volunteer trial carried out largely at home (home use test). Evaluation of the cosmetic product is always carried out in accordance with testing specification. Directions and frequency of applications is adjusted to cosmetic type, we also provide tests in beauty salons, hairdresser.
