Occlusive moisturizers

Occlusives are oils of non-human origin, often mixed with water and an emulsifier to form a lotion or cream. They provide a layer of oil on the skin's surface to reduce water loss from the stratum corneum.

  • Bath oil deposits a thin layer of oil on the skin when it comes out of the water.
  • Lotions are more occlusive than oils.
  • Creams are more occlusive again. The thicker barrier creams containing dimethicone are particularly useful for hand dermatitis.
  • Ointments are the most occlusive and include pure oil preparations, such as equal parts of smooth, liquid white paraffin or petrolatum.

The choice of stop emollient it depends on the body area and the degree of dryness and peeling of the skin.

  • Lotions are used for the scalp and other hairy areas and for mild dryness elsewhere

How often it is applied depends on how dry the skin is: Very dry skin can benefit from a greasy emollient every two hours, but slightly dry skin may only need a light moisturizer at night.
