Lotion is a skin softener used to treat dryness. Lotion moisturizes by slowing the evaporation of water from the upper layer of skin, making it a temporary treatment for dry skin. Lotions are generally easier and less messy to apply than creams. Lotions usually do not have an expiration date, so they can be used past their best-before date, as long as they are sealed tightly after every use and stored in a cool dark place.
How is lotion different from other types of moisturizers?
1. The main difference between lotion and moisturizer is that lotion is an emulsion of oil-in-water while moisturizer is an emulsion of water-in-oil. Lotion, therefore, contains more water than a moisturizer.
2. Another difference between lotion and moisturizer is that lotion usually contains added fragrance, while a moisturizer usually does not contain fragrance (although there are exceptions). The main purpose of fragrance in a lotion is to mask the odor from the oils used in it, which can be slightly unpleasant.
3. The biggest difference between lotion and moisturizer is that a moisturizer is usually applied on a daily basis, while lotion is applied only every now and then (though in some cases it can be applied daily as well). A moisturizer is dispensed through an applicator, for example an oil pump, while lotion is slathered directly on the skin.
4. Lotions are typically oil-based emulsions in which vegetable oils are used as emollients. Oils used in lotions include certain types of palm oil, shea butter, cocoa butter, corn oil and sweet almond oil.
5. A moisturizer doesn’t typically contain oil, and contains ingredients such as glycerin, a humectant that helps retain moisture; or urea, which is a potent skin conditioner.
6. Lotions are typically made with herbal extracts or essential oils that add fragrance, vitamins and minerals to lotions for skin treatment. These include vitamins A and E (antioxidants) and zinc oxide (a sunscreen).
The ingredients used in lotions can vary depending on the individual product, but they typically contain natural ingredients, such as oils and beeswax. In terms of application, lotions are applied in one of two ways: in a pump bottle or by dabbing on the skin with a finger.
