Rigourous Testing, Glowing Results.

Our formulas are backed by rigorous testing on men and women with all six skin colors on the Fitzpatrick phototype scale.

Our skincare products are developed with a commitment to rigorous scientific testing, ensuring they deliver real results for every skin type, tone, and texture. Every formula undergoes rigorous clinical trials and dermatologist assessments, and our eye serum is additionally evaluated by a licensed ophthalmologist.

Our Testing Process

Instrumental Testing

An instrumental test is performed to assess our product's effectiveness in moisturizing the skin, reducing wrinkles, and minimizing skin redness.

Advanced devices from Courage + Khazaka are utilized for precise measurements, including the Corneometer® CM 825 and Antera 3D® Pro.

Application Test

A home panel application test is conducted, where our test participants applied the product in their usual environment while maintaining regular contact with a dermatologist for guidance and feedback.

Effectiveness Criteria

To confirm the product’s efficacy, at least 50% of test participants had to report positive outcomes across each of the tested parameters.

This comprehensive approach ensures the accuracy and reliability of our product's benefits.
