Psoriasis is often perceived as just a skin problem by many. This chronic condition, which causes red, flaky and crusty patches covered with silvery scales on the skin, is usually considered a cosmetic or aesthetic issue. However, consultant dermatologist Dr Ch’ng Chin Chwen says: “It can be disfiguring and disabling. “Even if it is just on the skin, for some people, it can affect their palms and soles. “If this is severe and the skin cracks, it can affect how a person walks and works, especially for those people who need to work with their hands, e.g. bakers and nurses.”
