I started making my own sunblock after skin cancer nearly took my dad’s life in 2008. This event spurred me to look at solutions to protect my skin. I learned that the chemicals in sunblocks were linked to negative health effects in humans and coral reefs. Corals are incredibly sensitive to chemicals. It’s been shown in scientific literature that corals have shown abnormal bleaching with sunblock that’s a dilution of just 10 micrometers. That’s one millionth of a liter.
My search for healthy sunblocks took me to a couple natural alternatives produced in Australia, but they were expensive. I searched YouTube and found some tutorials on making sunblock from scratch. They worked pretty well and soon I was making my own block in my kitchen for pennies on the dollar (compared to off-the-shelf products). These experiments led our first Korduroy video in 2009, and then our Sun Care Basics video.
