I have heard these very enthusiastically compared to the Revlon Lip Butters in terms of moisture level, comfort and pigmentation. Sadly I don't have any lip butters to compare them to, but I can tell you that these are one of my favourite lip products of the moment.
Sheer but buildable, these lipsticks are luxuriously soft and moisturising on the lips and for such a soft product, they have really good staying power.
I waited so bloody long to finish this post that these lipsticks are now on sale at Priceline for $9.60 instead of the $12 I paid! Even at full price they're much cheaper than the Revlon Lip Butters. I really like the look of Berry Shortcake and Raspberry Sorbet. I haven't seen any swatches of those around, so I might have to try to get to a store to play with them.
Did you pick up any of the Moisture Lust lipsticks, or do you prefer your lipsticks with fuller pigmentation?
