• Mascara: 3 to 6 months. Mascara can easily get contaminated with bacteria, so it’s best to buy this staple several times a year.
  • Moisturizer: 3 months to a year. Manufacturers often include an expiration date on moisturizer, so it’s best to heed their recommendations.
  • Foundation: one year. If liquid foundation starts to change color or if it takes on an “off” smell (yuck!), throw it!
  • Powder: two years. It can last longer, but it tends to dry out.
  • Eyeshadow: powered shadow can last up to three years; cream shadows only last about a year.
  • Eyeliner and lipliner: up to two years. Sharpening these products helps to discourage bacterial growth.
  • Lipstick: two years. If it dries out, it’s time for a new shade!
  • Lipgloss: 18 months to 2 years.
  • Perfume: up to 2 years. To keep them lasting longer, store them in the fridge or away from direct sunlight.
