Does sunscreen expire?
Protecting our skin from the sun is essential to keep it healthy and youthful. We know that wearing sunscreen every day is crucial, but have you ever wondered if **sunscreen expires**? The answer is yes, and using an expired product can be just as harmful as not using sunscreen at all.
How long does sunscreen last after opening it?
Most sunscreens have a shelf life of approximately 12 months after opening. This is because contact with air and light can degrade the active ingredients that protect your skin from UV rays.
Where can I find the expiration date?
Finding the expiration date of your sunscreen is easy. Look for a symbol of an open jar with a number and the letter "M", for example, "12M". This number indicates how many months after opening the product is considered expired. You can also find an expiration date printed on the packaging.
How do I know if my sunscreen has expired?
Even if your sunscreen has not reached its expiration date, there are signs that it's no longer effective:
- Color changes: If the original color has changed, it's likely that the ingredients have degraded.
- Textural changes: If the texture has become more watery, grainy or separated, it's time to discard it
- Changes in odor: A rancid or unusual odor is also a bad sign.
Is it possible to use an expired sunscreen?
Not at all! An expired sunscreen will not adequately protect you from UVA and UVB rays, which increases the risk of sunburn, premature aging and even skin cancer.
Keep your sunscreen in good condition!
To make sure your sunscreen protects you properly, follow these tips:
- Store it in a cool, dry place, away from direct sunlight and heat.
- Do not leave it in the car for long periods, especially on hot days.
- Close tightly after each use to prevent oxidation.
