Are Sleek MakeUPs products dermatologically tested?
In this day and age very few companies carry out dermatological tests of the finished product unless they are supporting a product performance claim. Sleek MakeUP products are produced in factories that are ISO 9001 certified, and in turn only use raw materials that have undergone dermatological tests historically. Therefore, all our raw material suppliers have records of how their products react with the skin. They ensure that the product ingredients are ethically safe for topical application. In saying this, all of our products have undergone historical dermatological tests in accordance to our raw material (ingredients) suppliers.
