Can I use last year's sunscreen?
Using last year's sunscreen is generally not recommended. Sunscreens have an expiry date, and their effectiveness can decrease over time, especially if they have been opened or improperly stored. To ensure you are adequately protected from harmful UV rays, it's best to use a fresh bottle each season.
Key points:
- Sunscreen can lose its effectiveness after the expiry date.
- Opened sunscreen may degrade faster than unopened products.
- Proper storage is essential for maintaining sunscreen quality.
- Always check for changes in appearance or smell before use.
