Is This ‘Clean’ Mascara Actually Clean? A Greenwashing Investigation

Greenwashing Check
We investigated Glossier’s ‘clean’ mascara claim and found some dirty secrets.
Expert Analysis · Honest Reviews · Real Results
1.🔍The Clean Lie

Glossier’s Lash Slick is marketed as a ‘clean’ mascara. Their website is a minimalist dream of green promises.

The dirty secret? ‘Clean’ is an unregulated marketing term — and Glossier uses it while still including synthetic polymers and film-formers. It’s greenwashing, just prettier.

2.🌿The Pitch

A $18 tubing mascara that promises a ‘clean’, feathery look. The claim that hooked me? “Washes off with warm water.” No makeup remover needed.

1

Fibre-Free

Uses tubing technology to wrap lashes, not coat them in fibers.

2

Smudge-Proof

Dries down to a flexible film that resists raccoon eyes.

3

Buildable

Goes from a tint to a more defined lash in 2-3 coats.

3.⚠️The Ingredient Reality

The hero ingredient is Acrylates Copolymer — a synthetic polymer that creates the tubing effect. It’s not ‘dirty,’ but it’s not some earthy extract either. The ‘clean’ claim leans on what’s NOT in it (parabens, sulfates).

  • Acrylates Copolymer: The synthetic tubing agent
  • Beeswax: Adds a bit of natural conditioning
  • Propylene Glycol: A common humectant (not scary, just not ‘green’)
  • Panthenol (Pro-Vitamin B5): A legit lash conditioner

4.🧪The Feel Test

The formula is thin — almost watery. The brush is a skinny, precise spike. You feel the cool wetness, then it dries down completely weightless. No crunch.

By week two, the tube started drying out faster than my other mascaras. The ‘clean’ preservative system might be the culprit — a trade-off they don’t advertise.

💡

One Thing: Wiggle the brush at the very base of your lashes first. That’s where it deposits the most product for the tubing effect.

5.📜The Real Results

It delivers a perfect, separated, your-lashes-but-better look. Zero smudging on my oily lids. But volume? Forget it. It’s a lengthener and definer only.

Buy if
You want a natural, smudge-proof look and hate scrubbing with makeup remover.
⏭️

Skip if
You crave drama, volume, or have very straight lashes that need a stiff hold.
💰

Worth it?
At $18, it’s fine. But the ‘clean’ markup feels like paying for the aesthetic.

6.💡Final Call

A great tubing mascara trapped in a misleading ‘clean’ narrative. Buy it for the performance, not the planet-saving promise.

7.5/10
Great product, questionable marketing.
