Psoriasis is a skin condition that causes the rapid build-up of skin cells. Effects from the build-up process are forming of scales and red patches appearance. Normal life cycle of a skin cell is usually in a month. After a month, new skin will resurface while old dead skin will fall off.
That is not the case for psoriasis patient, the re-growth process of skin cell may occur within a few days. Thus, old skin doesn’t have enough time to fall off which lead to the build-up of skin cells. The scales and patches commonly appear in whitish-silver, red in colour and thicker than usual.
Scales from psoriasis typically develop on joints parts like elbows, knees and ankles. They may also develop anywhere on the body including hands, feet, neck, scalp and face. Some research has stated that psoriasis may be associated with several other conditions which are type 2 diabetes, inflammatory bowel disease, heart disease and psoriatic arthritis.
Psoriasis is a non-contagious skin disease. Touching a psoriatic lesion on another won’t cause you to develop the same condition. Expert and doctors have stated that the skin condition can’t be passed from one via skin contact.
