Ingredients to Avoid With Lash Extensions: Oil, Glycerin & Alcohol Explained

By MAGAL · Updated August 2026 · 6 min read
Quick answer

The three ingredients most likely to break down lash extension glue are oil, glycerin, and alcohol. Oil dissolves the cyanoacrylate bond, alcohol acts as a solvent that softens it, and glycerin is a humectant that pulls moisture into the bond and interferes with retention. Avoid products containing them around the eyes — especially oil-based cleansers, makeup removers, and 2-in-1 or moisturizing shampoos.

The 3 enemies of your lash bond

Lash extensions are held on by a cured cyanoacrylate bond. Three common ingredients attack that bond — and they're hiding in everyday products:

Oil — dissolves the bond

Oil is the classic enemy. It breaks down cured cyanoacrylate, so oil-based cleansers, makeup removers, facial oils, and rich creams cause extensions to slide off early. Check labels for mineral oil, coconut oil, and other oils, and switch to oil-free formulas around the eyes.

Alcohol — the solvent that softens glue

Alcohol acts as a solvent on cyanoacrylate. Alcohol-based toners, cleansing wipes, and some makeup removers can soften and weaken the bond over time. Keep them off the lash line.

Glycerin — the sneaky one

Glycerin is trickier because it's in so many "gentle" products — cleansers, toners, and especially shampoos. As a humectant it pulls and holds moisture right where the bond needs to stay stable, which can interfere with retention. Avoid heavy glycerin-based products near the eyes, particularly in the first day or two.

Where these ingredients hide

Oil-based makeup removers, cleansing balms and oils, 2-in-1 and moisturizing shampoos, alcohol toners and wipes, and rich eye creams. When in doubt, read the first five ingredients. (See our guide on the best shampoo for retention.)

What to use instead

The other half of the equation

Aftercare protects the bond — but the bond itself has to be strong to begin with. A robust, fully-cured adhesive is far more forgiving of real-life products and habits than a weak one.

Start with a bond that lasts

A stronger bond survives real life

MAGAL's Korean-made adhesive cures fully in 0.5–2 seconds and holds 5–7 weeks — NMP-free, hypoallergenic, with 72.5% lower formaldehyde (independently tested). For lash pros and brands: the more robust the glue, the more forgiving of everyday products. Sample it.

Can I use products with glycerin around lash extensions?

Glycerin is a humectant that attracts and holds moisture, which can interfere with the cyanoacrylate bond and shorten retention. It's common in cleansers, toners, and shampoos, so avoid heavy glycerin-based products around the eyes — especially in the first 24–48 hours after application.

Does alcohol damage lash glue?

Yes. Alcohol acts as a solvent and can soften or break down cyanoacrylate, weakening the bond. Keep alcohol-based toners, wipes, and makeup removers away from the lash line.

Why is oil bad for lash extensions?

Oil dissolves the cured adhesive bond, which is why oil-based cleansers, makeup removers, and many creams make extensions slide off early. Use oil-free products around the eyes.
