SPF: The Evolution of Sun Protection | Investor's Almanac

SPF, or Sun Protection Factor, has become a ubiquitous term in the world of skincare and sun protection. With a history dating back to the 1960s, SPF has evolved significantly over the years, from its initial introduction as a measure of UVB protection to the current broad-spectrum protection offered by modern sunscreens. The development of SPF is attributed to Swiss chemist Franz Greiter, who in 1938 suffered severe sunburn while climbing Mount Piz Buin, prompting him to develop the first commercial sunscreen, Piz Buin, in 1946. Today, SPF is a critical component of daily skincare routines, with the global sunscreen market projected to reach $13.7 billion by 2025. Despite its widespread adoption, SPF remains a topic of debate, with concerns surrounding its environmental impact, skin cancer prevention, and the efficacy of high SPF values. As the world grapples with the challenges of climate change and skin cancer, the future of SPF will likely involve innovative, eco-friendly formulations and a greater emphasis on education and awareness.
