Light enters the treatment room
The Science Museum’s medical history collection documents a period when sunlight and artificial light attracted wide interest as treatments. Its account describes Finsen’s late nineteenth-century work with concentrated light and the specialist lamps that followed.
From specialist equipment to the home
The museum also records the promotion of domestic tanning equipment in the 1920s and 1930s. These objects show how ideas about light moved into consumer culture. They do not establish that historical beauty rituals produced flawless skin. Read the museum’s illustrated history.
Different sources of light, different questions
Sunlight, historical ultraviolet equipment and modern red or blue LED devices should not be treated as interchangeable. The useful questions are specific: which light, which device, which intended use and which instructions?
