Formaldehyde in Eyelash Extension Glue: What You Need to Know

February 3, 2018



Lately, there has been a lot of concern about the use of formaldehyde in eyelash extension glue. Here’s what you need to know:


What Is It?

Formaldehyde is a colorless chemical with a very strong smell found in a lot of manufacturing products, including glue. It’s sometimes found in cosmetics, because of its use as a preservative. Formaldehyde is probably most famous for being used in embalming fluid at funeral homes.

Formaldehyde is also a known carcinogen, and prolonged exposure has been linked to cancer. Yikes! Brazilian blowouts, a hair treatment that leads to straighter, shinier hair, has become controversial because of its use of harsh chemicals like formaldehyde.


What Issues Is Formaldehyde Linked To?

Formaldehyde exposure has been linked to:

  • Cancer

  • Respiratory issues

  • Irritated, watery eyes

  • Severe inflammation of the eyes (especially when used in eyelash extension glue)

  • Headaches

  • Nausea
