* The size of the tube: Larger tubes will obviously last longer.
* How much product you use each time: If you apply several coats, you'll use it up faster.
* The formula of the mascara: Some formulas tend to dry out faster than others.
* How well you maintain the tube: Proper storage and avoiding pumping the wand can help prolong its life.
General Guidelines
* Health and Safety: Most experts recommend replacing your mascara every 3 months, regardless of how much is left. This is because mascara can harbor bacteria, which can lead to eye infections.
* Performance: You'll likely notice a change in performance before the 3-month mark. The formula may become dry, clumpy, or less effective.
* Estimated Uses: Assuming daily use, a typical tube *might* last for around 90 uses (if you're aiming for the 3-month replacement mark). However, this is just an estimate.
When to Throw it Away
Even if you haven't reached the 3-month mark, discard your mascara if:
* It smells different or strange.
* The texture has changed (dry, clumpy, thick).
* It's causing any irritation to your eyes.
* You've had an eye infection (throw it away immediately to avoid re-infection).
In summary, focus on the 3-month rule or any changes in the mascara's condition rather than trying to count the exact number of uses.
