From that favorite foundation you’ve had for years to the serum hiding in the back of your cabinet, beauty products don’t last forever. Using expired skincare or makeup can lead to irritation, breakouts, or worse. Knowing when to toss what—and how to store items properly—can help you protect your skin and get the most out of your investment.
The Hidden Risks of Expired Beauty Products
Expired beauty products can harbor bacteria, degrade in performance, and even cause adverse skin reactions. Mascara and liquid eyeliner, for example, are particularly prone to bacterial growth due to frequent exposure to air and the eye area. Lipsticks can dry out and change in texture, while foundations may separate or oxidize. Skincare items like SPF can lose their efficacy, leaving you unprotected. If a product looks or smells different than when you first bought it, it’s time to let it go.
A General Guide to Expiration Timelines
Each product category has its own typical shelf life:
- Mascara & Liquid Eyeliner: 3–6 months
- Liquid Foundation & Concealer: 6–12 months
- Lipstick & Lip Gloss: 1–2 years
- Powder Products (blush, eyeshadow, bronzer): Up to 2 years
- Skincare (serums, moisturizers): 6 months to 1 year (especially if they contain active ingredients)
- Sunscreen: Check the expiration date; usually 1–3 years
Some products display a PAO (Period After Opening) symbol—a tiny jar with a number (e.g., 12M for 12 months). Use this as a guide once you’ve opened a product.
Smart Storage = Longer Life
To help your beauty products last as long as possible, store them away from direct sunlight and heat. Keep lids tightly closed and avoid using your fingers directly in jars to prevent contamination. Opt for pumps or use clean tools like spatulas or brushes to scoop out creams. If possible, store certain items (like vitamin C serums or natural products) in a mini skincare fridge to slow oxidation.
When in Doubt, Toss It Out
Trust your senses—if something smells off, looks different, or feels strange on your skin, it’s safer to throw it away. Don’t risk irritation or infection just to hang onto that half-used product. Regularly checking your beauty shelf and decluttering expired items keeps your routine fresh, safe, and effective.
