I'm afraid I'm one of the people who really, really dislike frosty lipsticks. Even if the modern formulas feel better on the lips, the look still makes my lips look too dry for my taste and makes lip lines super exaggerated. I don't know. Don't see the appeal at all.
Ask me in a few months and maybe I will have found a frost lipstick that looks good. But until then, the most I can handle is a lipstick with a slight pearl, but even then I think it's too much!
Obviously this isn't to say they can't look great on other people (there's a reason they're on the market, after all), but definitely not the finish for me!
