Finding a clean mascara that performs as well as conventional formulas used to feel impossible. They were clumpy, flaky, or disappeared by lunchtime. But clean beauty brands have finally cracked the code, creating mascaras that rival — and sometimes surpass — their traditional counterparts.
We tested 30+ clean mascaras over 8 hours of wear to find the best performers. Here are our top 10 picks.
What Makes a Mascara "Clean"?
We look for mascaras free from:
- Parabens
- Phthalates
- Synthetic fragrances
- Carbon black
- Formaldehyde-releasing preservatives
- BHA/BHT

Pro Tips for Better Mascara Application
- Wiggle the wand at the base of lashes to deposit more product where you need volume
- Apply to top lashes first, then bottom — prevents transfer to your upper lid
- Use a clean spoolie to separate lashes before mascara fully dries
- Replace mascara every 3 months to prevent eye infections
- Don't pump the wand — it introduces air and dries out the formula faster
