Considered an "immune condition" by the Psoriasis Association, the skin of psoriasis sufferers can be painful, itchy and often times, a nuisance.
The charity said: "When a person has psoriasis, their skin replacement process speeds up, taking just a few days to replace skin cells that usually take 21-28 days." The Express explained that the condition affects up to 1.8 million people in the UK, and typically surfaces in early adulthood, or later on in life.
Research has discovered that psoriasis is caused when T-cells become overreactive. Those who suffer from the condition develop raised "plaques" that can be flaky, scaly and red on people's skin.
