Some may wonder: why aren't professional whitening products sold directly to consumers? The answer comes down to a simple principle: the more effective a product is, the more important it is that it is used in the right setting and under the supervision of a qualified professional.<\/p>\n

Regulation follows effectiveness<\/h2>\n

In many markets, regulators classify teeth whitening products by the concentration of the active ingredient and the method of use. In the European Union, for example, whitening products within a certain concentration range are available only through dentists, the first application is carried out under the dentist's supervision, and they are not used for persons under 18 years of age. In Saudi Arabia, these products are subject to the regulations and classifications of the Saudi Food and Drug Authority (SFDA).<\/p>\n
