It’s in the action
How do you load your mascara brush: by pumping or twisting?
For many of us, mascara pumping is habit. It’s one way to get mascara onto the brush. But this doesn’t mean it’s the only way or that it’s right. In fact, the pumping action alone can dry your mascara out prematurely as it forces air back into the mascara tube.
A better technique is to twist the brush. Once you’ve opened your mascara and while the brush is still in the tube, twist it 2-3 times before pulling it out completely. Twisting limits the air in-flow while still loading the brush with mascara. And if the mascara is relatively new, twisting should load the brush with enough mascara for both eyes.
