Why Moisturizer Expires
Bacterial Contamination
Jar moisturizers are especially prone to contamination because you dip your fingers in repeatedly.
SPF Degradation
Sunscreen ingredients break down over time and lose effectiveness, leaving you unprotected.
Ingredient Separation
Oil and water-based ingredients naturally separate, and preservatives can't keep them stable forever.
The Hidden Cost of Expired Moisturizer
Health Risks:
- Breakouts from bacteria
- Skin irritation
- Sun damage if SPF has degraded
- Allergic reactions
Note: These risks are why it's crucial to replace moisturizer regularly and watch for expiration signs.

Frequently Asked Questions
Can I use moisturizer past its expiration date?
It's not recommended. The PAO (Period After Opening) symbol on packaging indicates when moisturizer is most effective and safe. After this period, the formula may harbor bacteria, lose effectiveness, or cause skin reactions. When in doubt, throw it out.
How do I read the PAO symbol?
The PAO symbol looks like an open jar with a number and "M" (for months). For example, "12M" means the product should be used within 12 months after opening. This countdown starts when you first open and use the product, not when you purchase it.
Does unopened moisturizer expire?
Yes, even unopened products have a shelf life, typically 2-3 years from manufacture date. Look for a small jar icon without a number or a batch code. Once opened, the PAO period applies. Store unopened moisturizer in a cool, dark place.
What if my moisturizer expired but looks fine?
Even if it looks and smells normal, the preservatives may have broken down and bacteria could be present. It's better to be safe, especially for products used on your face. The expiration date exists for safety, not just quality.
