**ABSTRACT**
====The purpose of this experiment was to find which lipstick was the most durable. The main ingredients found in lipstick are wax, oil, alcohol, and pigment. Lipstick was wiped onto cling wrap and held in between a flashlight and a light probe. Bobbi Brown is considered to be the most durable.====

**CONCLUSION**
====Bobbi Brown is considered to be the most durable. This information is important to consumers to buy the better brand of lipstick. My hypothesis was correct; the more water that is applied to the lipstick the more light will shine through. Testing 24-hour lipstick with the same method would be a good follow up experiment.====
