@Geekish -I wanted to say that I was involved in a market research study regarding lip stains and I loved it. The company sent me a questionnaire and later sent me a prototype of the new lip stain formulation that they were coming out with.
They wanted me to try the lip stain and offer them my feedback. It had sheer coverage with a hint of color but instead of having a shine it had a matte finish so that it would stay on longer.
I really like it because I only had to reapply my lip stain a few times the entire day and the color held on well and it did not feather or bleed.
