e/Angel dusting

Information
has gloss	eng: Angel dusting is the misleading marketing practice of including a minuscule amount of an active ingredient in a cosmetic, cosmeceutical, dietary supplement, food product, or nutraceutical, insufficient to cause any measurable benefit. The advertising materials may claim that the ingredient is helpful and that the ingredient is contained in the product, both of which are true (with the exception of some extreme cases where the ingredient is so diluted that most units of the product don't even contain a single molecule of the active ingredient). However, no claim is made that the product contains enough of the active ingredient to have an effect — this is just assumed by the purchaser. Thus, while misleading, angel dusting is typically legal.
