Does Sunscreen Expire?
Many of us have been guilty of holding onto sunscreen for several seasons, wondering whether that bottle of Coppertone is still effective. If you’ve ever asked, "Does sunscreen expire?" you’re not alone. This article clarifies your questions about sunscreen shelf life.
The Shelf Life of Sunscreen
According to cosmetic chemist Dr. Julian Sass:
- Standard Expiration: Sunscreen has a lifespan of approximately three years from the date of manufacture.
- Opened vs. Unopened: Once opened, a sunscreen should ideally be used within six months for the best efficacy.
What to Check for Expiration
If the packaging lacks a clear expiration date:
- Smell, Texture, and Color: Always check for any changes in these characteristics. If you notice a difference, it’s better to discard it.
- Three-Year Rule: If it’s been over three years since its manufacture date, consider it expired, even if you bought it more recently.
Why Expired Sunscreen Is Ineffective
As sunscreen ages, the following changes may occur:
- Preservative Breakdown: Over time, preservatives weaken, making the product prone to contamination, which can contribute to skin irritation.
- Separation of Ingredients: The stabilizers that mix water and oil can begin to break down, leading to uneven UV protection. The SPF filters may also lose their effectiveness, turning the product nearly useless.
“Once the product starts to separate, you may not have an even distribution of UV filters, so the protection that the product provides can decrease," says Dr. Sass.
Key Takeaways on Expiration
- Think Holistically: The expiration consideration should go beyond just SPF filters; degradation of oils, binding ingredients, and water happens uniformly.
- Regular Checks: Always assess your sunscreen every few months and make a habit of replacing it annually if you’re unsure.
