荊棘油打底面部精華油（試用瓶）

Even though it's just a sample vial, the dropper makes it easy to get the perfect amount without waste. My makeup went on so much smoother over it, and a little really does go a long way for priming.

Two drops of this oil are plenty to prep my face before makeup, and the sample vial is honestly the perfect size to test if it agrees with your skin. I’m impressed how smoothly it sinks in without leaving any greasy film, so I’ll definitely be buying the full version once this runs out.

That little vial lasted way longer than I expected, and a few drops is all it takes to get my skin feeling prepped before makeup. It sinks in fast without any greasy residue, which is exactly what I want from a primer.
