Can you use an expired, unopened cosmetic product?

When you find an expired, unopened face cream , oil, or other cosmetic product at the bottom of a drawer, you often wonder if you can still use it. Is the expiration date of an unopened cosmetic product really a strict limit, or is there a margin of possible use? Let's explore the risks and precautions to take together.

Understanding the expiration date of cosmetics

Most cosmetic products display two types of indications regarding their duration of use:

• The expiration date (EXP) : often indicated in the form "EXP 12/2025", this date mainly concerns sun products , pharmaceutical care and certain sensitive cosmetics .
• PAO (Period After Opening) : represented by a pictogram of an open jar with an indication such as "12M" or "24M", it indicates the recommended duration of use after opening.

An unopened product normally retains its properties for a longer period of time. However, several factors can affect its quality, even before the date indicated.

At LActive , we have chosen to systematically indicate the expiration date (EXP) on our products in order to be completely transparent with our customers. This approach aims to simplify the lives of consumers , by providing them with clear information on the lifespan of their cosmetics and ensuring safe use.

Is an expired, unopened cosmetic product dangerous?

The effectiveness and safety of an expired product vary depending on its composition. Here are the main risks to consider:

1. Alteration of active ingredients

Some active ingredients, such as antioxidants, vitamin C, or sunscreens, lose their effectiveness over time. An expired cream containing these ingredients may therefore no longer be as effective, or even completely ineffective.

2. Change in texture and odor

An expired cream or oil may change texture, becoming more runny, grainy, or sticky. The smell may also be altered, a sign that chemical reactions have occurred. If your unopened, expired face cream has a suspicious odor, don't take any chances.

3. Development of bacteria and mold

A product containing water (such as a moisturizer) is more likely to develop bacteria over time, especially if its preservative system is weakened. An expired oil , while less at risk, can still oxidize and become irritating to the skin.

How do you know if an expired cosmetic product is still usable?

If you have an unopened expired cosmetic product , here are some criteria to check before using it:

• Appearance : Are there any color changes or phase separation?
• Odor : An unusual or rancid scent indicates spoilage.
• Texture : a product that is too liquid, grainy or sticky can be degraded.
• Ingredients : Natural cosmetics without preservatives deteriorate more quickly.

Can you use expired oil?

Vegetable oils , such as argan or coconut oil, are less susceptible to bacteria but can oxidize over time. Expired oil can develop a rancid odor and become irritating to the skin. If this is the case, it is best not to apply it to the face or body.

Some tips for keeping your cosmetics longer

To avoid waste and extend the life of your products , here are some tips:

• Store them in a cool, dry place , away from light and humidity.
• Avoid temperature variations , especially for sensitive oils and creams.
• Do not dip your fingers into a jar : use a clean spatula to avoid contamination.
• Close containers tightly after each use to limit oxidation.

Conclusion: Should you use an unopened expired cosmetic product?

It all depends on the type of product and its condition. An expired, unopened face cream may still be usable if it shows no signs of deterioration. However, if the texture, scent, or color have changed, it's best not to take any risks.

When in doubt, caution is advised. Expired cosmetics can cause allergic reactions or be ineffective. To avoid these problems, adopt good storage practices and use your beauty products wisely!
