Psoriasis is an autoimmune skin disease. In this disorder, patches of skin become thick, red, itchy and scaly. This is called plaque. Psoriasis develops when the immune system destroys skin cells. The skin reacts to this by producing skin cells rapidly, which leads to the formation of plaque.
Indications
The National Psoriasis Foundation reports that topical psoriasis medications such as creams are usually used to start psoriasis treatment. Some psoriasis creams are available over the counter, and others must be purchased with a doctors prescription.
Types
Creams that contain vitamin D analogues, coal tar, corticosteroids and salicyclic acid may be used to treat psoriasis. Other creams such as anthralin and topical retinoids are also creams that may be used to treat psoriasis.
Effects
Coal tar creams reduce itching and scales in psoriasis. Creams with salicyclic acid stimulate peeling of skin cells and reduce scales on the skin. In psoriasis, corticosteroid creams suppress the immune system and slow down skin cell production. Anthralin removes scales while vitamin D analogues slow down reduce skin cell production.
