Skin absorption, What is it? Why it is important?

The skin is a barrier of the body. Its out layer is responsible for keeping water in the body and keeping other harmful chemicals and pathogens out, making skin a natural barrier to infection. However, it does allow some chemicals to pass through and enter the body. This is so called skin absorption which refers to transporting chemicals from the outer surface of the skin into the skin or even into other part of the body when skin exposed to chemicals or cosmetic products. Absorption of substances through the skin depends on duration of contact, concentration and solubility of the substance as well as physical condition of the skin itself. When applying skin products, it is important that the product is not toxic. If it is toxic, it is not only harmful to the skin, but also it can get into the body causing harm to the whole body.
