To prolong the life of any blush, clean your blush brush regularly and store the color in a dark, dry place to avoid promoting bacterial growth. Moisture can also come in the form of residue from your foundation and face cream, says Dubroff: “If you apply blush over those products, the oils cling to the hairs and transfer to the blush. cheeks.” This will eventually cause a dull gray film to form on powder formulas or a white, chalky layer on creams. To prevent this from happening, after applying foundation and moisturizer, wait a few minutes before putting on blush. You can also blot excess oil from your face first, then once your blush is applied, immediately wipe your brush with a dry towel.
With powders or creams, texture is also an indicator that it’s time to blend. If the formula has become so hard that it no longer budges from the compact, it’s time to buy a new one.
Eyeliner ? Yes please. Those that irritate the eyes? No thanks. To prevent your eyes from reddening or itching, replace powder eyeshadow every six to nine months, according to Hammer. Even though their formulation is similar to that of other powders, because they are constantly in contact with a mucous membrane, there is a higher risk of transferring bacteria to the product and then to the eyes.
Pay particular attention to cream-based shadows, which tend to grow bacteria faster than powders. If you use your fingers to apply, wash your hands before doing so and watch out for color changes or unpleasant odors.
Liquid or pencil, these eye contours should be replaced approximately every three months. Like eyeshadow, they’re applied near a sensitive area and can pick up bacteria and bring them back into the eye very easily “without any visible signs of contamination,” Hammer warns. If you’ve used a dirty liner, you may experience redness, itching or, in extreme cases, conjunctivitis.
Pencils will last a little longer than liquid liners if you’re faithful to regular sharpening, but you’ll know they’re dead once a white film starts to develop on the tip that can’t be sharpened, said Dubroff.
Lipstick and lip gloss
The wrong color can ruin your mood, but the risk of a lipstick or lip gloss formula going bad (or growing bacteria) is low because they don’t contain water, Hammer says. But since they’re repeatedly exposed to the mouth, he suggests replacing lip products after a year — or if you’ve recently been sick. Teschendorf agrees, saying Seduce“Traditional anhydrous lipsticks have the potential to last a bit longer because their top surface can be cleaned between uses, but a year is still a good rule of thumb.”
