Sunless tanning
cosmetic technique and products for producing a tan-like appearance without ultraviolet exposure

Sunless tanning refers to the effect of a suntan without exposure to the Sun. Sunless tanning involves the use of oral agents (carotenids), or creams, lotions or sprays applied to the skin. Skin-applied products may be skin-reactive agents or temporary bronzers (colorants).
Sunless tanning has emerged as an alternative to UV exposure (from sunlight or indoor tanning), which has been linked to increased risk of skin cancer.
The chemical compound dihydroxyacetone (DHA) is used in sunless tanning products in concentrations of 3%-5%. DHA concentration is adjusted to provide darker and lighter shades of tan. The reaction of keratin protein present in skin and DHA is responsible for the production of pigmentation.
History
The tanning effect of dihydroxyacetone (DHA) was discovered in the 1950s by Eva Wittgenstein at Cincinnati Children's Hospital, who observed that DHA used in an oral treatment stained the skin brown on contact. The first commercial DHA self-tanner, Man-Tan, appeared in 1959, followed by Coppertone's "QT" (Quick Tan) in 1960; both produced an orange-toned result that gave early self-tanners a poor reputation. Reformulated products and, from the late 1990s, automated spray-tan booths broadened the market.

Why this record matters
A short description can identify a subject without explaining its stakes. For “Sunless tanning”, the useful work is to connect “cosmetic technique and products for producing a tan-like appearance without ultraviolet exposure” to the records capable of establishing context and consequence.
Vocabulary and entity names are the principal evidence signals here, because they determine the precision of every later search. The source revision retrieved here is dated Jul 18, 2026. The linked authority identifier is Q995634. None of the 0 selected statements returned an explicit reference. The first chronological checks are 1959 and 1960.
The absence of detail may reflect summary conventions rather than a lack of surviving documentation. The source lead contains qualifying language; that uncertainty should survive quotation, summary and reuse. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
