Treatment of Itching is (http://en.wikipedia.org/wiki/Itch) –
- Steroids (destroys the cells) and
- Antihistamine (reduces the fluid build up)
Histamine works by setting of a chain reaction which includes increase in blood supply to the area.
Antihistamines work by reducing the bluid up of fluid (blood) or by sedating.
Excessive fluid build is the main reason for Itching.
Build up of fluids in the layers of the skin will be caused due to use of moisturisers and soaps together.
Acids wash away the natural skin oils. That causes excessive supply of fluids to the soap washed skin.
Moisturisers are muscle relaxant. When applied externally, the moisturisers do not all the oils present in the skin to reach to surface due to passive nature of muscle relaxants.
