It’s important to check the expiration date on the bottle or look for signs of deterioration, such as a change in color or consistency, a strong, rancid smell, or if it’s been over a year since you bought it, to determine if your sunscreen is still good.
Does Sunscreen Have an Expiration Date?

Typically, sunscreen will have an expiration date printed on the bottle, typically three years after the date of manufacture. If your sunscreen doesn’t have an expiration date, you can use the following guidelines to determine if it’s still good:
- If the sunscreen has changed color or consistency, it may be expired and should be discarded.
- If the sunscreen has a strong, rancid smell, it’s likely past its prime and should be replaced.
- If you’ve had the sunscreen for more than a year and have used it regularly, it may be time to replace it.
The Dangers of Using Expired Sunscreen
Using expired sunscreen can be dangerous for your skin, as it can cause skin irritation, sunburn, and an increased risk of skin cancer. When the active ingredients in sunscreen break down, they can become irritating to the skin, causing rashes, itching, and other uncomfortable symptoms. Additionally, expired sunscreen may also contain bacteria and other harmful substances that can cause skin infections.
What You Can Do to Extend the Shelf Life of Your Sunscreen
To extend the shelf life of your sunscreen and ensure its effectiveness, follow these tips:
- Store your sunscreen in a cool, dry place: Sunscreen should be stored in a cool, dry place, away from direct sunlight and heat sources. Exposure to heat and sunlight can cause the active ingredients in sunscreen to break down, reducing the effectiveness of the product.
- Keep the lid tightly closed: To prevent the active ingredients from breaking down and to protect the product from contaminants, it’s crucial to keep the lid of your sunscreen tightly closed when not in use.
- Use a separate container for travel: When traveling, it’s a good idea to use a separate container for your sunscreen to prevent it from being damaged or exposed to extreme temperatures. This will help ensure that the sunscreen remains effective and provides the protection you need.
- Avoid exposing your sunscreen to high temperatures: It’s necessary to avoid exposing your sunscreen to high temperatures, such as leaving it in a hot car or on a windowsill. High temperatures can cause the active ingredients to break down and the formula to become less effective.
- Use a stable, broad-spectrum sunscreen with a high SPF: To ensure maximum protection against both UVA and UVB rays, it’s better to use a stable, broad-spectrum sunscreen with a high SPF. Look for a product that has been tested and proven to provide effective sun protection.
- Reapply your sunscreen every two hours: Sunscreen should be reapplied every two hours, especially after swimming, sweating, or toweling off. This will help ensure that you are getting the full protection that the product is designed to provide.
By following these tips, you can extend the shelf life of your sunscreen and ensure that you are protected against harmful UV rays. Don’t forget to check the expiration date of your sunscreen regularly and replace it as needed.
