EFFICACY CLINICAL STUDIES

A product’s efficacy studies consist in demonstrating its allegation(s) / claim(s) by quantifying its effects on skin, eyes or mucosa.

Checking that your products do cause the expected effects is crucial for their commercialization and the respect of future consumers.

The Dermscan methods and protocols come from a close to 30 years old recognized know-how. Always updated to meet your today requirements and anticipate tomorrow’s, we clearly quantify and visualize your product’s effects.

We can offer you several complementary approaches:

  • In use test.
  • Instrumental measurements.
  • Sensory analysis by our regularly trained panelist.

Statistical analyses are carried out on your results in order to precisely determine the evolution of the studied parameters and draw conclusions on your products’ efficacy

IN USE TEST

Whatever your claim, the in use test is inescapable! It consists in:

  • Several weeks utilization of a product by volunteers under normal conditions and based on your packaging recommendations.
  • A medical examination to determine its proper tolerance.
  • After being used by subjects allowing to check its effects, a subjective evaluation questionnaire.
