Face and body moisturizers are essential to most beauty regimens. As a basic skin care component, moisturizers are known for their ability to soothe and protect dry and aging skin. Dermatologists recommend it, and aestheticians lavish it on their clients. Even the simplest drugstore moisturizer can feel luxurious and pampering -- particularly to dry, flaky or itchy skin.

Some of these ingredients can be as basic and unremarkable as lanolin or mineral oil. Though effective, these elements don't necessarily convey a sumptuous skin care experience to moisturizer users. Therefore, moisturizer manufacturers will often add in more lavish -- even unusual -- components. Take a look at the five most exotic (and bizarre) moisturizer ingredients.
