How Long Should You Really Keep Your Beauty Products? The Truth About Product Expiration

Posted by Trudy Petith on 13th Aug 2025

We get it - you’ve got that makeup bag stuffed full, your skincare shelf looking like a mini pharmacy, and some products that have probably been hanging around longer than you’d care to admit. But when was the last time you checked if your beloved products are still good to use? If you’re unsure, don’t worry, you’re not alone. Today, we’re breaking down everything you need to know about product expiration and why tossing out old beauty products is one of the best things you can do for your skin (and your glow).

Why Does Product Expiration Matter?

Expired beauty products aren’t just less effective, they can actually be harmful. Over time, ingredients break down, preservatives lose their power, and bacteria can creep in, potentially causing irritation, breakouts, or infections. Using products past their prime is like trying to get a caffeine hit from day-old coffee, just disappointing, and maybe a bit risky.

How Long Do Products Last?

Here’s a quick guide to the average lifespan of some of the most popular beauty products after opening:

  • Mascara & Liquid Eyeliner: 3 to 6 months

  • Foundation & Concealer: 6 to 12 months

  • Lipstick & Lip Gloss: 1 to 2 years

  • Powder Products (Blush, Eyeshadow, Face Powder): 2 to 3 years

  • Skincare (Moisturisers, Serums, Sunscreens): Generally 12 to 18 months, but active ingredients like retinol and vitamin C may need replacing sooner

  • Sunscreen: Replace every year (yes, every year!) — effectiveness fades even if it hasn’t expired on the label

How to Know When to Toss It

Look for the PAO (Period After Opening) symbol on your packaging—a little jar icon with a number and an ‘M’ (for months). This tells you how long a product is good for after opening. For example, 12M means 12 months.

If you don’t see a PAO symbol, check for an expiration date or any changes in texture, smell, or color. If a product smells funky, separates, or looks weird, it’s time to say goodbye.

Tips to Keep Your Products Fresh Longer

  • Close lids tightly to avoid contamination

  • Store products in a cool, dry place away from direct sunlight

  • Avoid using your fingers—opt for clean spatulas or applicators

  • Don’t share products to reduce the risk of bacteria spreading

Bottom Line: Your Skin Deserves Freshness

Regularly decluttering your beauty stash might feel like a chore, but it’s essential for maintaining healthy, radiant skin. Using fresh, effective products means better results, and fewer surprises (we’re looking at you, mysterious breakouts).
