Until recently I would energetically pump the tube before applying mascara to my lashes. By pumping I mean vigorously moving the brush around in the mascara tube to get a good coat of lash paint onto the brush. One of my clients, who has been in the beauty industry for decades, mentioned that pumping the brush causes liquid mascara to go clumpy and thick. It has something to do with the addition of air into the solution as you pump that causes the clumps.

My lovely client suggested that a gentle ninety degree twist of the brush is sufficient, and that will keep your mascara solution thin and smooth for longer. So I started a new mascara tube and have religiously NOT pumped the tube.

Who else pumps their mascara tube?
