Dermatitis
Conditions
Brief summary
The dermatological testing of cosmetic products which are new on the market, or existing products with novel formulations is common and a useful procedure, yet necessary to alleviate common irritants and contact allergic reactions. Cosmetic products contain a range of substances that may be considered as potential irritants or contact allergens. In order to estimate that risk, cosmetics are tested by applying patch tests.
