Dithrocream Forte 0.5% 50g: Dithrocream contains the active ingredient Dithranol, which is a medicine applied to the skin to treat psoriasis. Psoriasis is a condition in which thickened, scaly patches or plaques of skin form. These are the result of excessive production of skin cells. Dithranol works by slowing down the process of skin cell production. It is applied only to the psoriasis plaques & not to normal healthy skin. The Dithranol is absorbed into the skin cells & inhibits DNA replication in these cells. This slows down cell division & stops the cells from multiplying excessively. In turn, this reduces the thickening & scaling of the skin & clears up the psoriasis plaques.
