Mascara 睫毛膏
This is the makeup item you should be most vigilant about: As the brush is taken out, applied, and put back in the tube, it brings with it any bacteria that has collected along the way, explains cosmetic chemist Jim Hammer. Lingering bacteria can cause redness and itchiness, or even conjunctivitis (a.k.a. pinkeye) and sties. Switch mascara every two to three months to be safe. "It will also have a distinct gasoline-like smell once it's gone bad," says makeup artist Pati Dubroff. If you develop any negative symptoms, immediately throw out any of your eye makeup that may have been contaminated. If your eyes are still irritated a day or two later, see an eye doctor。
Tips:刷子一進一出,就會帶進很多細菌。每兩三個月更換一支睫毛膏最好。當睫毛膏聞起來有汽油味的時候就說明壞了。
