Buying Guide: Key Considerations For Thick-Lash Seekers

  • Brush design matters: A flexible, multi-bristle brush tends to separate and lift for a fuller fan of lashes, while a dense brush can deliver more volume with fewer coats.
  • Formula type: Waterproof or long-wear formulas hold better on oily lids and during heat, but require richer removers. Washable formulas are easier to remove and better for daily wear.
  • Clumping control: Look for claims or reviews about clump resistance. Primers or combs can help with separation if you notice sticking after application.
  • Wear and sensitivity: If you have sensitive eyes or wear contacts, choose ophthalmologist-tested options and fragrance-free formulas when possible.
  • Shade choice: Blackest Black provides the most dramatic contrast for bold looks, while Brown-Black offers a softer, everyday effect.
