I failed science at school so this was very hard for me. I had no idea what all the words meant. I didn't know why brands put this and that inside lipstick – I had no idea. So I had to do my own research and then figure out what's good, what goes into what and how to mix certain ingredients. I basically had to teach myself and I was so determined to make it mine. The formulas changed quite a few times. As I went along, I tried them on myself and my friends – Mata Labs is cruelty-free! Yes, there were a few hiccups when I first started, but for someone who failed chemistry, I've done pretty well. I've nailed this formula. When people started to pick up on the products, they kept asking, "What is that? How do I use that? Where do I get that from?" That's when I knew I was doing something right.
