Cosmetic products are regulated by the FDA. If a product's intended use includes beautifying, promoting attractiveness, adding fragrance, deodorizing, or altering the appearance of the human body, it's a cosmetic.
Common cosmetics include:
- lotion and moisturizer
- fingernail polishes
- eye and facial makeup
- soap, cleansers, shampoos, and conditioners
- massage oils
Promoting attractiveness and altering the appearance of the human body may seem like broad terms, but think literally to avoid confusion. One's appearance doesn't have to be altered drastically for it to be changed; many personal care products promote attractiveness in ways we don't typically consider "cosmetic" benefits.
A shampoo's intended use is to cleanse hair and leave the user with a more clean appearance; an exfoliator's intended use is to improve the appearance of the skin by reducing visible dryness or flaking; the intended use of perfumes and colognes is to leave a noticeable scent on the user, so they're considered to promote attractiveness.
