There are several ways of how anti wrinkle creams work. Wrinkles are basically caused by the natural dryness and thinning of the skin, which is only natural when one gets older. The most basic function of anti wrinkle cream is usually as moisturizer, so that the skin will not be dry. The next way is to exfoliate; that is to remove any dead cells from the skin and to give younger and fresher look. Other ways are by using collagen, sun protection, chemical peeling, and many more. While some anti wrinkle creams have specific functions, most of them usually combine several ingredients to give several treatment, thus provide the most benefits.
