Glossier’s Lash Slick mascara is labeled ‘clean.’ That word is doing a lot of work.
The real test? The ingredient list — and whether the formula performs like a mascara or a sad, watery tint.
It’s a $20 tubing mascara from Glossier. The promise: a natural, defined, and clump-free fringe. No smudging.
Tubing Formula
Wraps each lash in a polymer tube for removal with warm water.
Fibre Brush
A skinny, precise wand for lower lashes and corners.
Clean at Sephora
Meets Sephora’s ‘Clean’ standards, banning 50+ ingredients.

The hero is the tubing polymer. It’s not groundbreaking — lots of drugstore mascaras use it. The ‘clean’ part means no parabens or formaldehydes.
But ‘clean’ doesn’t mean inert. Some ingredients are there for marketing, not your lashes.
- Acrylates Copolymer: The tubing film-former
- Pro-Vitamin B5: A basic conditioner
- Beeswax: For texture, not a vegan formula
- Jojoba Esters: Adds a slight sheen

The formula is thin — almost like tinted water. You won’t get volume. At all. It’s strictly length and separation.
After two weeks, I noticed zero lash conditioning. The ‘clean’ benefit is what’s *not* in it, not what it does for you.

It delivers a true your-lashes-but-better look. Zero smudging on my oily lids. Also zero drama — it’s the most boring mascara I own.

It’s a clean-ish mascara that does one thing well. Not greenwashing, but not a revelation either.
