that manifests itself on the skin with peeling, especially on the face, elbows, knees, and scalp, although it can spread throughout the body. It usually appears in young people (between fifteen and thirty-five years old), but it can appear at any age, including children.
Until a few years ago, there was little known about this disease and its cause. We currently know that factors such as stress, nutrition and aggressive products for the skin can have an important factor in its appearance.
There are many types of psoriasis, the most common is plaque psoriasis, which usually appears on elbows and knees. There are other types such as the one shown on the palms of the hand and the sole of the foot, the scalp (which manifests itself in the form of dandruff), the nails (a thickening of the nails appears), inverted psoriasis (in English or armpits), gut rate psoriasis (which arises all over the body in the form of tear drops), etc.
Psoriasis affects other organs in addition to the skin. Up to 30% of people with psoriasis have arthritis, especially if psoriasis comes from stress, since stress produces inflammation and inflammation affects the joints, mainly in the hands, feet, spine, wrists and knees. Apart from the joints, psoriasis is also associated with other types of diseases such as obesity and diabetes.
The cause of psoriasis is in the T lymphocyte. This group of cells work more than they should and produce excessive growth of skin cells. Normally, the skin is renewed in 30 days, but in people with psoriasis it does so in 4 days, which generates the accumulation of cells in the outermost layers of the skin.
Climate also influences psoriasis. Psoriasis improves in spring and summer and in humid and hot climates. The cold and low humidity of the environment makes this condition worse. Another alternative to improve psoriasis is the use of skin products made with natural ingredients and avoid those made with aggressive ingredients, such as industrial products with detergents or petroleum derivatives.
