Psoriasis is a chronic skin disease that causes inflammation and flaking. Generally, it is caused by stress and a lack of (preventative) care.
As the Colombian Dermatologists Association states, this is a condition that most frequently occurs on the skin, known as plaque psoriasis. Its more aggressive forms, however, can attack the joints and the eyes.
These lesions appear as bright red spots that are normally large in scale. They primarily appear on the scalp, face, elbows and knees, although they can also affect the intergluteal cleft and male genitalia. (Related article: Basic skin care).
While its cause is still unknown, the Association for Patients and Family Members with Psoriasis and Psoriatic Arthritis in Barcelona, Spain, explains that this condition is connected to certain genes, which is why it is more common in people who have family members also affected by it.
Similarly, there are also factors that can worsen this condition such as stress, cold weather, poor skincare, injury, infections such as pharyngitis and tonsillitis, the excess consumption of alcohol, heavy smoking, or medications such as an anti-inflammatories and drugs for high blood pressure.
