It is the responsibility of the Ministry of Health to ascertain the intended purpose of a cosmetic product and if it fulfills that purpose as stated on the packaging. In addition, the Ministry of Health must ensure that the ingredients contained in cosmetics are worthy of use, cannot cause harm to the user, and are not known to be substances that are dangerous to the public. However, sometimes people develop irritations, sensitivities or allergies to substances found in cosmetics, such as lead, aluminum, parabens (preservatives) and more.
