Eczema (also known as atopic dermatitis) commonly presents in young children and may even go dormant for a period of time with relapses in adulthood. Eczema may be part of an “atopic” picture, involving other conditions of the immune system such as asthma and hay fever. Psoriasis is a skin condition characterised by an overproduction of skin cells that build-up to form thick, scaly patches that are dry and itchy. Stress commonly causes exacerbations of this condition.
