How to Sanitize False Lashes After Every Wear

I once wore a gorgeous pair of $20 false lashes three times without cleaning them. By the fourth wear, my eyelids were swollen, pink, and painfully tender. My longtime eye doctor took one look and said, "Congratulations, you gave yourself bacterial conjunctivitis." All because I skipped a 5-minute cleanup routine.

WHY YOUR LASHES TURN INTO A BREEDING GROUND

Your lashes come into contact with your skin, eye makeup, mascara, and your fingers — and that's before they even touch your eyelids. The band especially collects oil, dead skin cells, bacteria, and old adhesive residue. In a 2021 study published in Contact Lens & Anterior Eye, researchers found that reused false lashes without proper cleaning harbored up to 7 different types of bacteria, including staphylococcus and streptococcus. Leave them dirty, and you're not just risking a stye — you're risking an infection that can keep you away from makeup for weeks.

STEP-BY-STEP: HOW TO SANITIZE AFTER EVERY WEAR

Remove all adhesive residue: After taking off the lashes, gently peel away the band with tweezers to remove glue clumps. Never pull at the fibers.
Soak in 70% isopropyl alcohol: Place your synthetic lashes in a small dish or cup of 70% isopropyl alcohol for exactly 2 minutes. This kills 99.9% of bacteria without damaging the fibers. Note: This is only for synthetic and mink-free lashes. If your lashes contain mink or silk, skip the alcohol and use a specialized lash shampoo instead.
Blot, don't rub: Gently press the lashes between two clean paper towels. Rubbing can fray the lash points.
Air dry completely: Lay the lashes on a clean tissue in their original tray, and let them dry for at least 10 minutes. Never store them damp — moisture promotes bacterial growth.
Store in a sealed case: Once dry, place them back in their tray and close the lid to protect from dust and airborne particles.

WHAT NOT TO DO WHEN CLEANING FALSIES

Don't use water and soap alone: Soap leaves a film that actually attracts dirt. Alcohol or a dedicated lash cleanser is better.
Don't soak them overnight: That will ruin the curl and loosen the band.
Don't use makeup wipes: They're not antibacterial enough, and the oily residues linger.
Don't wear them if you have an active eye infection: Toss the pair immediately to prevent re-contamination.

Here's what your eyes deserve after hours of wearing falsies: a clean pair that won't cause a doctor visit. If you care for them properly, a single pair of quality false lashes can be worn 5-7 times. That daily 5-minute routine saves you money, protects your vision, and keeps every wear as fresh as the first.

LASH CLEANING FAQ

Can I sanitize false lashes with hand sanitizer?

No. Hand sanitizer contains gels and thickeners that will coat the lash band and leave a residue. Stick to 70% isopropyl alcohol or a lash cleaner.

How often should I replace my false lashes even if I sanitize them?

Plan to replace synthetic lashes after 5-7 wears. If the band loses its curve or the fibers start to separate, it's time to say goodbye. Immediately discard lashes after an eye infection.

Is alcohol safe for all types of lashes?

No. Alcohol is safe for synthetic and acrylic lashes. Mink, silk, and other natural hair fibers can be damaged, so use a gentle, oil-free lash shampoo and pat dry.
