When cosmetic products come into contact with the eyes, consumers expect absolute mildness.
Eye irritation is one of the most common reasons for complaints about shampoos, shower gels and cleansers or suncare products.
Dermatest now offers a clear solution for brands that want to prove their products are truly gentle: the No Tears Seal.
This seal is only awarded to products that successfully pass Dermatest’s scientifically validated testing method.
It provides manufacturers with credible proof that their formulations are eye-friendly and it gives consumers the safety they need when choosing products for themselves and their families.
Design of the in-vitro study for “No Tears”
- Ethical testing, no harm to test persons and no animal testing
- Dermatest relies exclusively on advanced, non-invasive methods. The test is performed on a three-dimensional reconstructed human cornea-like model that mimics the properties of the human eye.
- Determination of the ET-50 value
- The ET-50 value measures how long it takes until 50% of the corneal tissue cells are no longer viable under the influence of the product. The longer this process takes, the milder the product.
- Scientifically reproducible results
- The test provides objective, comparable data that allow brands to substantiate “No Tears” claims with confidence.
