I've been on a huge thebalm kick lately; I just can't get enough of the wonderful products and adorable packaging. I work long days, and cannot STAND creasing, so was looking for a serious primer that would keep my eye makeup intact all day. This absolutely does the trick. I can leave for work at 6:30AM, work all day, and go out after work and I swear my eye makeup looks exactly the same at 9:30 PM. Zero creasing, zero touchups required. I also love that this is a true sheer formula; it doesn't sparkle or shimmer or tint my eyelids. Feels a bit thick out of the tube, but absorbs so quickly on the lids it doesn't feel like anything. You only need the tiniest amount, so I'm sure this will last forever!
