One of the interesting products I have had the opportunity to use over the years has been the lip glaze from Stila. **Product Details** Stila Lip Glaze is a unique lip gloss system. It comes in a clear tube which has a clear snap on lid and the other end has a knob to turn. You can see the gloss through the tube, and then as you turn the knob, a plunger moves up gradually into the gloss and pushes it up through a brush which is on the end of the tube- an applicator. The colors tend to be on the very sheer side, some are creamy some are sparkly . Most of them are flavored to reflect fruity flavors, or flavors of drinks, etc. **Product Performance** Stila Lip Glaze is one of those products that has a list of positives, but also negatives. *Positives:* These lip glazes are easy to see so that you know how much is left in the tube. They are lightly scented but not flavored heavily. The glosses are not overly sticky, and the colors are interesting and sometimes very pretty- such as the Jewel versions they came out with at Christmas time. *Negatives:* The gloss is hard to estimate- if you turn the knob, nothing comes out and then all of a sudden, the pressure is so high on the gloss that it comes oozing out of the brush too much and you have to put it all somewhere before you put the cap back on. Another thing I don't like is that these glosses tend to go rancid pretty quickly. And once you turn the knob one way, you can not turn it back- EVER. **The Bottom Line** A very convenient lip gloss with a brush and see through to gauge how much you have left, this gloss can also be frustrating to use when too much comes out of the tube. It also has a tendency to go rancid fast, so collecting these to use over a few years is not a great idea. The colors are VERY sheer so if you are looking for heavy coverage, you should probably look elsewhere.
