If you read the label of your body wash, you'll probably find a long list of difficult-to-pronounce ingredients. But if you see any of the following ingredients, your body wash contains a moisturizer:
- mineral oil
- soybean oil
- jojoba oil
- almond oil
- aloe vera
- olive oil
- shea butter [source: American Academy of Dermatology]
Many of these ingredients -- such as soybean oil -- are lipids, or oil-soluble molecules, that replace natural oils removed from the skin during cleansing [sources: Bruno, Case]. Other ingredients are emollients and humectants. Emollients -- such as petrolatum -- remain in the outermost layer of the skin and act as lubricants, while humectants -- such as glycerin -- help trap moisture in the skin [source: Mayo Clinic].
