The Quick Answer
Replace mascara every 3 months, regardless of how much is left. Mascara tubes are breeding grounds for bacteria. Never share mascara or use it past its expiration.
| Item | Frequency | Signs It Needs Attention |
|---|---|---|
| Mascara | Every 3 months | Mascara is clumpy or dry, It smells different than when new |
Why Every 3 months? (The "Why It Matters")
The dark, moist environment of a mascara tube is perfect for bacterial growth. Using old mascara can cause eye infections, styes, and even serious conditions like conjunctivitis.

Frequently Asked Questions
Can I use mascara longer if it still looks fine?
No. Bacteria aren't visible. The 3-month rule is about safety, not product quality.
What about waterproof mascara?
Same 3-month rule. Waterproof formulas may dry out faster but still harbor bacteria.
