Patch tests, application tests, studies on damaged skin – testing the skin tolerance of topical and ophthalmic products.
We can investigate the tolerability of your product with a series of epicutaneous tests. This determines whether a test product causes a reaction after application to the skin. The different test designs differ, e.g., in the duration of the application phase, the test area, the type of application (open, semi-occlusive, occlusive). We also recommend appropriate designs for specific product categories.
The epicutaneous tests are usually performed on the skin of healthy test subjects. As an option, we can offer you testing on special collectives. In addition, we consider subjects with sensitive skin, depending on the respective test design. Our offering of simple and repetitive epicutaneous tests includes:
In Dermatology, Oral Care, Ophthalmology, Hair Care, Women’s Health and Sun Care
If the product is actually used by the end user on particularly sensitive skin (e.g., in the area of the mucosa or on baby skin), this must be taken into account in the test procedure. In this case, carrying out the tolerability test on intentionally damaged skin makes sense. By damaging the skin, its reactive potential to the provocation that has taken place is increased, thus placing the tolerability of the test product under intense scrutiny. We are able to damage the skin using various methods. We offer the following test designs
The most realistic test is the dermatological-controlled use test, which evaluates the tolerability of the test product after a two-week application period. In addition to the dermatological assessment, subjective parameters such as itching, burning, and a feeling of tightness are also assessed as part of the study, and the cosmetic acceptance is evaluated.
The dermatological evaluation can be carried out by a specialist (dermatologist, pediatrician, gynecologist, ophthalmologist, dentist, ENT specialist), a general practitioner, or a trained evaluator. In addition, two test products can be investigated in a split design, and the questionnaire can be statistically evaluated. We are happy to offer additional options on request
The statement “dermatologically tested” or “dermatologically approved” is not protected and may be written on the products as soon as any test with investigation of skin tolerability with appropriate positive outcome has been performed under dermatological control. Under certain conditions in may be possible to apply the statement ‘clinically tested’. Please contact us in order to discuss this option.
