Back in 1994, a 17-year-old Princess Victoria of Sweden looked sweet with her glowing complexion and sun-kissed locks. Today, the royal still has a youthful appearance thanks to her natural makeup and signature smile. In case you didn't know, the princess is an avid supporter of living a sustainable lifestyle. On top of being aware of her carbon footprint and trying to be a responsible consumer, the monarch was also appointed by the United Nations to promote the organization's Sustainable Development Goals in 2016.
