Assessment of local Tolerance
The COSDERMA Laboratory specialises in assessing the Efficacy of cosmetic products. We also carry out cutaneous, oral and/or ocular Acceptability tests (Use tests) under the supervision of a specialist (Dermatologist, Dentist or Ophthalmologist) only in association with an Efficacy test. This Use test can be coupled with the Comedogenicity assessment.
* Patch tests, ROAT tests are only performed internally in the search for the imputability of the tested product in the case of an adverse event (AE).
Cutaneous acceptability, ocular and oral
The purpose of these tests is to confirm the acceptability of the finished products after application under normal conditions of use by the subjects at home:
Use test under dermatological, ophthalmological or dental control
Principle
Clinical examination at the beginning and at the end of the study
Interest
- Primarily physical signs data
- Normal conditions of use for 21 or 28 days
- Target panel
- Physical (Investigator) and functional (subjects) signs
- Cosmetic acceptability / performance
- Comparative tests (versus reference, excipient, modified formula…)
- Claim “under the control of a Dermatologist…”
Limitations
Interpretation, imputability of the product ( Decision table for the imputability of adverse effects related to cosmetic products, ANSM)
Non comedogenicity test
Principle
Clinical examination and counting of retentional and inflammatory elements at the beginning and at the end of the study
Interest
- Normal conditions of use for 21 or 28 days
- Claim: “non-comedogenic product”
Limitations
Sensitivity
