The consensus
What reviewers found
Synthesized across the trust-weighted source mix below.
L'Oreal's Infallible Grip Mechanical Gel comes up across the reviewers we read as the drugstore answer to a premium gel pencil. popsugar.com tested the 36-hour claim and reports the pencil stayed put for eight hours of real wear, which is the kind of grounded measurement that translates to most users. r/drugstoreMUA commenters describe it as a 'cannot believe how well it works' surprise, and a separate r/MakeupAddiction rave on a related L'Oreal Infallible pencil compares its color payoff to Urban Decay's Zero.
What reviewers liked
- popsugar.com confirmed approximately 8 hours of real-world wear
- r/drugstoreMUA and r/MakeupAddiction threads consistently positive on color payoff
- Mechanical-pencil format avoids sharpening
- Under $10 with strong shade range
Where it falls short
- Ulta retailer review directly contradicts the smudge-proof claim
- 36-hour wear claim is not supported by any expert source we read
- Long-wear performance varies significantly by skin oil level per community reports

The pushback is meaningful. An Ulta product-page review flatly states 'there's nothing smudge-resistant or waterproof about this eyeliner,' reporting transfer to the lower lash line within a day. That contradiction between expert testing and a subset of retailer reviewers is exactly the pattern you see across most 'long-wear' claims in this category, performance depends heavily on skin chemistry and oil levels.
At under $10 with a mechanical-pencil format that doesn't need sharpening, the consensus across mainstream press and specialist communities is that this is one of the strongest gel pencils in the drugstore tier, with realistic expectations of 8-12 hours rather than 36.

I cannot believe how well it works! Goes on great, doesn't smudge and not too expensive. I won't buy anything else now.
L'oréal Infallible Super Slim has been my best. The tip is super precise and it has a comfortable grip. Also very dark pigment and while not ...
