Artificial Tanning

In the 1920s and 1930s, certain luxury European hotels installed artificial tanning machines intended to reproduce the sun's effects. The tanned complexion then became a modern symbol associated with vacations, sport, and health. Yet a few decades earlier, bronzed skin remained linked to manual labor and popular classes.

In the early 20th century, medicine already experimented with light's effects on the organism: alpine heliotherapy, treatments against rickets, phototherapy lamps in hospitals. The Nobel Prize in physiology awarded to Niels Finsen in 1903 for his research on light reinforced the idea that rays possessed measurable therapeutic virtues. When beauty institutes and cures took up these technologies in the 1920s, artificial tanning borrowed as much from science as from fashion.

The devices resembled clinical equipment: metal frameworks, orientable reflectors, cabins or chairs equipped with ultraviolet tubes. The user did not expose themselves to the open sky; they followed a calibrated lighting duration, eyes partially protected, in an entirely controlled environment. The gesture held as much of the medical session as the leisure ritual—especially since advertising insisted on "vitality," "solar hygiene," and the supposed benefits of UV on energy, skin, or even mood.

This offer fit into an era fascinated by electricity, neons, and the technical possibility of reproducing natural environment effects. The tanned complexion ceased being the simple residue of a summer or an outdoor profession to become an attribute one could acquire and maintain independently of season. The first cabins thus marked a stage where the modern body already thought itself as modifiable surface, exposed to machines capable of artificially fabricating signs once imposed by environment.
