Sunbed use induces the photoaging-associated mitochondrial common deletion.

Sunbeds have become very popular and, as a result, health effects of their use are of growing concern. In this regard, exposure to ultraviolet radiation from sunbeds may cause premature skin aging. Evidence for this assumption, however, has thus far been elusive.

Ultraviolet-free phototherapy.

Background: Ultraviolet (UV) radiation phototherapy has been used for decades in the management of common skin diseases. On the other hand, UV radiation is a complete carcinogen and as a consequence, UV phototherapy is usually not used for the long-term management of children and young adults and in combination with topical or systemic immunosuppressants.

Purpose: The therapeutic effectiveness of a new UV-free irradiation device in the treatment of patients with atopic hand and/or foot eczema was studied.
