How Often Should I Replace My Mascara?

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.

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.

Same 3-month rule. Waterproof formulas may dry out faster but still harbor bacteria.
