While sunscreen's development was a global effort, Australia is credited with creating the first commercially successful sunscreen.
Although early forms of sun protection existed elsewhere, Milton Blake, an Australian chemist, developed and marketed the first commercially viable sunscreen through his company, Hamilton. Before this, sun protection was common in Australia, highlighting the country's proactive approach to addressing the harmful effects of the sun due to its climate and high UV levels.
Therefore, while the concept of sun protection has a long history in various cultures, Australia stands out for its early commercial innovation in this field.
