Do Skin Care Products Expire? Here's What You Should Know

We’re all in the habit of checking expiration dates on groceries, especially with how quickly things can spoil in the fridge. But when’s the last time you gave your bathroom shelf the same attention? Just like food, skin care products have a shelf life—and using them past their prime could be doing more harm than good.

 

Yes, Skin Care Has a Shelf Life

Whether you’re using a luxe face serum or a drugstore moisturizer, every product eventually expires. Unlike food labels in Canada, skincare expiration dates aren’t always clear. You might see a PAO (Period After Opening) symbol on the packaging—a tiny jar icon with a number like “6M” or “12M”—which tells you how many months the product is good for once opened.

While Health Canada doesn’t require expiration dates on cosmetics unless the product has a drug component (like sunscreen or acne treatment), most reputable brands include one anyway. Storage and hygiene habits also affect longevity—so how you treat your products really matters.

 

Typical Shelf Life of Popular Products

While it’s always best to follow the manufacturer’s recommendations, here’s a general idea of how long your go-to skincare staples tend to last:

Moisturizers
Unopened, they can last up to 2.5 years. Once opened, aim to use them within 12 months. After that, the texture can break down or bacteria might start to creep in—especially if you’re dipping your fingers into a jar.

Serums, Retinoids & Vitamin-Based Products
If they come in pumps or tubes, they’re less exposed to air and bacteria and can usually last up to a year. Jarred formulas? Plan to replace them within 6 months after opening.

Masks
Cream or gel masks (like Patchology’s fan-favourites) tend to last 2–3 years sealed, or about a year once opened. Clay or all-natural masks may dry out quicker, especially in dry climates like Alberta or during our cold winters.

 

How to Spot Expired Skin Care

Still hanging onto that face cream you bought during a Boxing Day sale two years ago? It might be time to let go. Here are some signs it’s time to toss your products:

• A noticeable change in colour or smell
• A shift in texture—think separation or a watery consistency
• Skin irritation or breakouts after use

Even if a product hasn’t technically expired, if it’s acting differently or affecting your skin, it’s better to play it safe. Expired skincare can lose effectiveness—or worse, cause irritation or infection.

 

Tips to Help Your Skin Care Last Longer

Want to get the most out of your skin care investments? These simple habits go a long way:

• Store products in a cool, dry space—avoid direct sunlight or hot bathrooms.
• Keep lids tightly sealed.
• Choose pumps or tubes over jars when possible.
• Avoid sharing personal products, especially creams or anything that touches your face directly.
• Check your products every few months and do a seasonal clean-out.

 

Time to Refresh?

Clearing out expired products is a small step that can make a big difference in how your skin looks and feels. Think of it like a mini reset—an easy way to keep your routine clean, safe, and effective.
