Piz Buin began after a Swiss chemistry student suffered from overexposure to the sun when climbing the Piz Buin Mountain in the Alps. In 1946, he invented the first sun protection product for those who wanted to enjoy nature's bounty in the light of the sun. Piz Buin was also one of the first companies to implement the Sun Protection Factor, or SPF, with its products. Today, Piz Buin offers a wide range of advanced sun protection products as well as sunless tanning products.
