Eyelash extensions are a real asset for enhancing your eyes every day. They allow you to have long, full, and curled lashes without makeup. But to enjoy them for a long time, it's essential to adopt the right habits... and above all, to avoid certain elements that can seriously compromise their hold .

So, what's the worst enemy of eyelash extensions? The answer is clear: humidity and oily products , which damage the glue and significantly shorten the lifespan of the extensions. Here's a complete guide to understand why, and discover all the other enemies to absolutely avoid .


1. Humidity: The number one enemy of eyelash extensions

The glue used for eyelash extensions is based on cyanoacrylate, a molecule that is very sensitive to humidity. As soon as the extensions are exposed to water vapor , hot water or very humid environments , the glue degrades.

Concretely, this means:

  • A much shorter outfit

  • Extensions that fall out prematurely

  • A risk of irritation or detachment in patches

To avoid:

  • Long hot showers

  • The hammam , the sauna , the heated swimming pools

  • Intensive sports sessions immediately after the installation

  • Wet the eyelashes within 24 to 48 hours after application.


2. Fatty substances: guaranteed dissolution of the glue

Another formidable enemy: oil-based products , whether contained in a makeup remover, treatment, or makeup.

Oils degrade the glue and cause extensions to fall out faster. They can also cause residue to build up at the root of the eyelashes, leading to poor hygiene and the risk of inflammation.

Products to avoid:

  • Two-phase or oil-based makeup removers

  • Eye creams that are too rich

  • Oily or waterproof eyeliners and mascaras

  • Vegetable oils (even natural)

To be favored:

  • Oil-free makeup removers , formulated specifically for extensions

  • Gentle, non-greasy, alcohol-free foaming cleansers


3. Excessive friction: mechanical wear of the extensions

Rubbing your eyes, sleeping on your stomach or using overly abrasive cotton pads are habits that mechanically damage extensions.

Friction causes breakage or premature detachment of extensions , weakening the glue and natural eyelashes.

To avoid:

  • Rubbing your eyes (especially when you wake up)

  • Use rough towels or dry cottons

  • Sleeping with your face against the pillow

To do:

  • Use a soft eyelash wipe or reusable wipe

  • Avoid sudden movements while cleaning

  • Sleep preferably on your back


4. Unsuitable makeup: a false ally for extensions

Conventional mascaras , even oil-free ones, are not recommended for extensions. They can stick the lashes together, weigh down the base and weaken the application.

Waterproof eyeliners are also problematic because they require intensive makeup removal.

To avoid:

  • Mascara on extensions (except specific mascara for extensions)

  • Oily pencils, long-lasting eyeliner

  • Creamy or glittery eyeshadows (difficult to remove)


5. Lack of maintenance: an aggravating factor

Not cleaning your extensions regularly promotes:

  • The accumulation of sebum and dust

  • The development of bacteria

  • Premature loss of natural eyelashes and extensions

Recommended maintenance:

  • Gentle cleansing every 2 to 3 days with a suitable cleanser

  • Brush the eyelashes with a special extension brush

  • Perform a refill every 3 to 4 weeks


Conclusion: A suitable routine for extensions that last

The worst enemy of eyelash extensions is undoubtedly humidity , followed closely by oily products and bad habits such as rubbing or poor maintenance.

To keep your extensions longer:

  • Avoid water for the first 48 hours

  • Ban fatty substances

  • Don't rub your eyes

  • Use gentle care and cleansers
