What is psoriasis, Psoriasis is not a simple rash, but a disease that can become painful and debilitating and affects the development of daily activities. It is caused by the malfunction of the immune system that causes excess production of skin cells, responsible for replenishing the layers of skin, in constant renewal. This excess reaches a substitution level up to seven times higher than normal, giving rise to the characteristic plaques of the disease, which take the form of highlighted red spots covered with scaling. In addition, excess cell production also causes the infiltration of white blood cells (T cells) into the skin. The lesions are usually located on the trunk, elbows, knees, scalp and English. For very dry skin. 220 g container.
