So, I've been using this for the past couple of months, I didn't post about it earlier because I wanted to see how it fared when the weather heated up. Being in a squeezy tube applicator with a small nozzel, it's very easy to control the amount of product and very little is required. I find less is more with this. The reason being that the colour is very white and too much means teadeous blending.
That aside, this seems to feel kind of cooling when applied and dries quite quickly. Lasting power is average, while it does make the shadow last longer and gives the colour some punch, it's not infallible and won't keep things from creasing for an infinity, but for a full day of work and the trip home, this works nicely. The fact that so little is needed means this should last for ages:-)
