QACS clinical efficacy testing includes

  • In use tests
  • Ophthalmological tests
  • Dermatological tests – Patch and HRIPT tests
  • standard & custom testing protocols

  • We maintain a pool of more than 1000 volunteers, male or female, aged 18 to 65, covering a wide range of specific characteristics (e.g. sensitive skin, comedones, oily skin, normal skin, dry skin, normal eyes, contact lens wearers etc.).
  • Skin type diversity facilitates all types of cosmetic efficacy testing and enables product claims substantiation.
  • Test panel can be customized according to your needs.

Throughout the study, we provide evaluation by expert dermatologists and ophthalmologists.

At the end of the study, you receive a final report, which includes:

  • Data interpretation and statistical analysis
  • Documented experts opinion
  • Panelists opinion
  • High-resolution images of the skin surface for marketing purposes upon request

If you are based in the EU, we offer 24-hour courier service.
