my thoughts on the formula: It’s a thicker, nearly non-sticky but it has this faint tackiness, along with a subtle, spiced vanilla scent. I have not found the majority of the range to have much pigmentation, so the differences between each gloss is minimal. They last four hours on me, which is shy of the six they’re proposed to last. My concern with these glosses in the amount you get — a mere 0.10 oz. Most glosses are more like 0.20 oz. They do have SPF 15 in them, which is a nice touch.
