It in a third of the people that they suffer this pathology is evident the presence of a hereditary

The skin is formed by a fine external layer, the epidermis and an internal resistant and flexible layer, the dermis.

The base of the epidermis is formed by alive smoothed cells that they go replacing continually to those another that they come off in the surface, in a process that from the basal layer to the cutaneous hard stratum around 28 days.

The dermis, on the other hand, is formed only for alive cells and they in her are also sanguine glasses, that they feed the epidermis.

Recent investigations indicate that the psoriasis is a disorder of the system immunológic that causes the hyperactivity of the T [linfocitos] in the cells of the skin.
These T [linfocitos] produces the inflammation of the skin and an excessive renovation of the external cells of the skin (epidermis) that it take place in 4 days, instead of the 28 normal days (seven times quicker), they for this accumulate the layers of dead skin, that come off in form of flakes; the cells of the skin conserve the nucleus, they don't mature and they don't grant the appropriate protection, there is lost of humidity and elasticity for the lesions.

In the psoriasis lesions the skin is thicker by increasing the number of cells of the epidermis. The capillaries are thicker and long that in the normal skin, tangled on itself, and the blood flows in more amount, for this the badges appear red (papulosis). In some cases could produce serious forms of psoriasis.
