Chemical SPFs are quickly absorbed into the skin and work by absorbing UV to protect the skin. Mineral SPFs, also known as physical sun creams, work as a barrier on the skin that reflects UV. The Australian Gold botanical range is made up of mineral SPFs that are reef-safe, as they do not contain harmful chemicals that can harm the ocean. Some countries are now only allowing the use of mineral SPFs to ensure the safety of their reefs. These lotions are designed to be water-resistant for up to 80 minutes and can be easily removed with soap or a cleanser.
