Skin damaged by expired skincare? 5 warning signs to watch out for!
Skin care is important, but did you know that the skin care products you are using have an expiration date? Ignoring the expiration date of skin care products can lead to adverse results for your skin. This article will give you insights into the importance of skin care product expiration dates, how to recognize the signs, and how to store them to ensure they are at their best.
Why is the expiration date of skin care products important?
Like food, skin care products have a limited shelf life. Over time, the active ingredients in a product can deteriorate, making it less effective or not as effective as expected. Additionally, expired products can cause skin problems, such as:
- Reduced effectiveness: Active ingredients such as vitamin C or retinol degrade over time, making them less effective.
- Irritation: Deteriorated ingredients may cause skin irritation, allergic reactions, or redness.
- Bacterial contamination: Products left open for too long can become contaminated with bacteria and fungi, which can lead to infections or breakouts.
5 Warning Signs Your Skincare Products Have Expired
While there’s not always a clear expiration date on the packaging, there are several signs that your product may have expired:
- Changes in texture: The product may thicken, separate, harden, or become unusually liquid.
- Color Change: The color of the product may darken, fade, or change to another color.
- Unusual smell: A rancid, sour, or unfamiliar smell.
- Separation of ingredients: You can see the oil separating from the product.
- Damaged packaging: The container is swollen, has cracks, or the lid does not close tightly.

How to check and extend the shelf life of skincare products
- Look for the PAO (Period After Opening) symbol: This symbol is an open jar with a number followed by the letter “M” (e.g. 6M, 12M) indicating how long the product will last after opening (in months).
- Write down the opening date: You can write the opening date of the product on the packaging to help you remember.
- Proper storage: Store the product in a dry, cool place and away from direct sunlight to prevent deterioration.
- Avoid direct finger contact: Use a spatula or spoon to scoop out the product to reduce contamination from bacteria on your hands.
- Watch out for high-risk products: Products with high active ingredients, such as vitamin C or AHA/BHA, tend to have a shorter shelf life, and water-based products are more susceptible to contamination.
