Makeup Expiration Date Calculator
How to Use This Tool
Select your makeup product type from the dropdown menu, then enter the date you first opened the product. Click the "Calculate Expiration" button to see when it will expire. Use the "Reset" button to clear all fields and start over. The tool will show the expiration date, days remaining, and a status message.
Formula and Logic
This calculator uses standard cosmetic industry guidelines for product shelf life after opening. The expiration date is calculated by adding the typical months of usability for each product type to the opened date. For example, mascara is typically good for 3 months after opening, while powder products can last 24 months.
Practical Notes
- Always check for changes in smell, texture, or color as additional indicators of expiration.
- Store makeup in a cool, dry place to maximize its shelf life.
- Consider labeling products with the opened date using a permanent marker.
- For expensive products, prioritize using them first to avoid waste.
- When in doubt, throw it out—especially for eye and lip products.
