Your makeup applicators could be breeding grounds for bacteria, which can led to acne, clogged pores, and impurities on your skin. Not so pretty.



First step, make sure your makeup hasn't expired. Mascara, because of its proximity to the eyes, should be replaced every three months, states Blisstree. "Most other makeup should be discarded after one year," said Dr. Carol L. Clinton, of skincare company Timeless Skin Solutions, in the article. "You'll notice that its consistency changes, and that any SPF in the product will have deteriorated."

Her advice: Clean your brushes weekly to keep a significant amount of bacteria from accumulating in the brush. If you use a brush daily to apply liquid makeup, however, you'll need to clean it daily.
