Quality of life (QoL) is the physical, psychological and social well-being of an individual (WHO definition of 1949). QoL in this context does not so much include "the objective availability of material and immaterial things", but the degree to which a desired state of physical, psychological and social well-being is actually achieved. QoL can only be measured by a self-assessment of the patient. Standardised questionnaires are suitable for this purpose, which are filled out by the patient himself (self-assessment) or by examiners or family members (external assessment, "proxy survey"). QL should be a target criterion in dermatological therapy studies and should be considered in addition to somatic and, if necessary, economic parameters.
