Piz Buin (brand)

Piz Buin is the trading name of a sunscreen firm, whose headquarters is in Zug, Switzerland. It is named after Piz Buin, a 3312 metre-high mountain in the Eastern Alps.

The Piz Buin brand traces its origin back to the inspiration of Franz Greiter, a young chemistry student, who suffered severe sunburn while climbing Piz Buin in 1938.[1] He introduced his first sun protection product in 1946.[2][3]

In 1974, Greiter adapted earlier calculations from Friedrich Ellinger and Rudolf Schulze and introduced the "sun protection factor" (SPF), which has become a worldwide standard for measuring the effectiveness of sunscreen.[4]
