Moisturizer

Moisturisers or moisturizers (see spelling differences) are complex mixtures of chemical agents specially designed to make the external layers of the skin (epidermis) softer and more pliable, by increasing its hydration (water content) by reducing evaporation. Naturally occurring skin lipids and sterols as well as artificial or natural oils, humectants, emollients, lubricants, etc. may be part of the composition of commercial skin moisturizers. They usually are available as commercial products for cosmetic and therapeutic uses, but can also be made at home using common pharmacy ingredients.

Moisturizers prevent and treat dry skin, protect sensitive skin, improve skin tone and texture, and mask imperfections.[1]

Risks of moisturizers

Two factors have to be considered when assessing the safety of a moisturizer:

1. The safety of the ingredients it contains. There are on-line databases like Skin Deep where consumers can get information about individual cosmetic ingredients.[2]

2. The risk of bacterial contamination.

A recent study discovered that the application of certain moisturizers increases the incidence of skin cancer in mice.[3] Four popular moisturizers were tested, providing the same result. It is not yet known if the same applies to humans. A fifth moisturizer, specially prepared without mineral oil and sodium lauryl sulphate, had no such effect.[4]

Some people are sensitive or allergic to certain products, and this can cause outbreaks.

There is a risk of moisturizers being contaminated with bacteria that can cause disease.
