Bobbi Brown Ultra Violet is a very cool-toned, light purple with a sheer finish. It is a permanent lipgloss that retails for $24.00 and contains 0.24 oz.
Bobbi Brown Ultra Violet Sheer Color Lip Gloss ($23.00 for 0.24 fl. oz.) is described as a "sheer violet pink." It's a sheer pop of purpled pink with cool, berry-like undertones. This formula is supposed to be sheer, so the color is just right; it's noticeable but not dominating and lets the natural lip color come through. I couldn't think of a perfect dupe for the color, though. Illamasqua Move has similar coloring but it's opaque, so it looks very different.
Bobbi has sized up all her glosses to give you an extra dose of shine. Wear it on its own for sheer color or swipe it on top of lipstick for extra shine, plus the new tapered applicator lets you apply it like a pro. Bonus: Sheer Color Lip Gloss is infused with soothing botanical extracts to keep lips healthy and soft.
