No, you should not use expired mascara on your eyes.
Expired mascara is one of the riskiest beauty products to use past its expiration date — and most dermatologists and ophthalmologists strongly advise against it. Here's why, along with clear guidelines on how long mascara actually lasts, the real dangers, and what to do if you accidentally use old mascara.
Why Expired Mascara Is Dangerous
Mascara is applied directly to the eyelashes and very close to the sensitive eye area. Once opened, the tube becomes a breeding ground for bacteria (especially Staphylococcus and Pseudomonas) because:
- You dip the wand in and out repeatedly → introduces eye bacteria, skin oils, and moisture.
- The dark, warm, moist environment inside the tube is ideal for bacterial growth.
- Preservatives (like parabens or phenoxyethanol) break down over time and lose effectiveness.
Using expired mascara can lead to:
- Eye infections — conjunctivitis (pink eye), styes, blepharitis (inflamed eyelids)
- Corneal scratches or ulcers — if dried mascara particles flake off and scratch the cornea
- Allergic reactions — old formula can become unstable and irritate the delicate eye area
- Chronic irritation — redness, itching, swelling, even long-term damage in severe cases
In 2026, ophthalmologists still report cases of bacterial keratitis (serious corneal infection) linked to old mascara — some requiring antibiotics or even hospitalization.
How Long Does Mascara Really Last?
- Unopened: 2–3 years from manufacture date (check the PAO symbol — open jar icon with number of months, e.g., “6M” = 6 months after opening).
- Opened:
- Most experts (American Academy of Ophthalmology, FDA guidelines) recommend 3–6 months maximum
- Many derms now say replace every 3 months for safety, especially if you have sensitive eyes or wear contacts
- If it smells off, looks clumpy, dried out, or has separated liquid — throw it away immediately (even if not yet 3 months)
Signs Your Mascara Is Expired or Unsafe
- Dried out or crumbly texture
- Clumps or flakes when applying
- Separated liquid at the bottom
- Bad/rancid smell (not the original scent)
- Wand has visible gunk or discoloration
- Eyes feel irritated, itchy, or watery after use
What to Do If You’ve Used Expired Mascara
- Stop using it immediately — do not finish the tube.
- Rinse eyes with sterile saline or clean cool water if irritation starts.
- Monitor for symptoms — redness, swelling, discharge, pain, light sensitivity.
- See an eye doctor if any symptoms last more than 1–2 days or worsen.
- Replace the mascara — buy a fresh tube and discard the old one.
How to Make Mascara Last Longer & Stay Safe
- Replace every 3 months — mark the date you open it on the tube with a Sharpie.
- Don’t pump the wand — this pushes air in and dries it out faster.
- Store upright in a cool, dry place (not bathroom — humidity speeds bacteria).
- Never share mascara — even with family.
- Use a separate tube for top and bottom lashes if you’re very cautious.
Bottom Line
Can you use expired mascara? Technically yes — but you really shouldn’t. The risk of eye infection (some potentially sight-threatening) far outweighs the cost of a $10–$30 new tube.
Replace mascara every 3 months — or sooner if it looks/smells off. Your eyes are worth it.
