Rare Beauty Perfect Strokes Longwear Gel Eyeliner

Editor's Take
A high-performance waterproof liner built on silicones and petrochemical waxes; it delivers on smudge-proof durability, not on clean chemistry.
Four-pillar formula scores

- Clean Beauty: 7.3 / 10
- Sustainability: 5.9 / 10
The Verdict
This is an old-guard synthetic makeup formula doing exactly what it was designed to do: stay put. The trimethylsiloxysilicate resin and isododecane solvent create a fast-setting, waterproof film that won't budge through sweat or tears. The organoclay rheology system ensures smooth application without dragging, and the pigment suspension is genuinely modern. The trade-off is environmental: the base is a parade of persistent petrochemicals and silicones that score poorly on biodegradability and green chemistry alignment. Carbon Black raises flags in stricter clean frameworks. If you want a liner that survives a marathon, this delivers. If you want one that aligns with sustainability values, keep looking.
