Foundation (cosmetics)
Foundation is a liquid, cream, or powder makeup applied to the face and neck to create an even, uniform color to the complexion, cover flaws and, sometimes, to change the natural skin tone. Foundation makes the face flawless and glowing, but if not applied properly, it gives a cakey and patchy look. Some foundations also function as a moisturizer, sunscreen, astringent or base layer for more complex cosmetics. Foundation applied to the body is generally referred to as "body painting" or "body makeup".
Safety[edit]
Per- and polyfluoroalkyl substances (PFAS)[edit]
A 2021 study tested 231 makeup and personal care products and found organic fluorine, an indicator of PFAS, in more than half of the samples. High levels of fluorine were most commonly identified in waterproof mascara (82% of brands tested), foundations (63%), and liquid lipstick (62%).[18][19] As many as 13 types of individual PFAS compounds were found in each product.[18] Since PFAS compounds are highly mobile, they are readily absorbed through human skin and through tear ducts, and such products on lips are often unwittingly ingested. Manufacturers often fail to label their products as containing PFAS, which makes it difficult for cosmetics consumers to avoid products containing PFAS.[20]
