While previous civilizations used various measures to limit sun exposure, research points to 1928 as the first documented use of a sunscreen emulsion in the United States, which used UVB filters to protect against sunburn (5). However, there’s a bit of debate among historians about who actually invented the first commercialized sunscreen. That aside, we do know development of specifications for sun protection factors didn’t occur until 1974, and in 1980 the first documented sunscreen with UVA filters was released (6). In the decades since then, sunscreen formulations have improved leaps and bounds in terms of aesthetics, efficacy, and options for all skin types and skin tones.
