How does an electric eyelash curler work?

June 08, 2025

An electric eyelash curler is the innovation in beauty tools: it offers a fast, safe and long-lasting way to give your eyelashes a natural curl.

Unlike a traditional eyelash curler, an electric version uses heat, similar to a straightener for your hair, to effectively shape your lashes.

But how exactly does such an electric eyelash curler work? And what should you pay attention to when choosing the right model?

In this blog, we will explain to you step by step how an electric eyelash curler works, how to use it safely and why more and more people are choosing this tool as a regular part of their daily beauty routine.

What exactly is an electric eyelash curler?

An electric eyelash curler is a compact device that curls your lashes using hot technology. Applying light heat makes your lashes smoother and allows them to curl upward more easily and for a longer period of time. It's basically the difference between trying to style your hair cold, or blow-drying it hot: with heat, the results last longer.

There are roughly two types:

Brush eyelash curlers
Tang-shaped electric curlers, resembling the classic eyelash curler but with a heated clamp

Key Benefits:

Longer lasting curl
Less chance of kinking or damaging lashes
Easy to use and quick results

How to use an electric eyelash curler step by step?

To get the most out of your electric eyelash curler, proper technique is important. Follow these steps for optimal results:

1. Apply mascara first (optional).

With brush-type electric eyelash curlers, such as Costiq's, you do get to apply mascara first. In fact, for many users, this enhances the curl effect. Just make sure the mascara has dried slightly (not soaking wet) to prevent it from running out or clumping.

⚠️ Note: This sequence applies specifically to brush-shaped models. For tong-shaped electric curlers, do use them on clean lashes first, before mascara.

2. Turn on the device

Most electric eyelash curlers, are up to temperature within 15-60 seconds. An indicator light usually shows when it is ready to use.

3. Curl your lashes

Place the heated brush at the base of your upper lashes and slowly brush upward, pressing lightly against the lashes. Hold in position for 5-10 seconds for lasting results.

4. Repeat if desired

For added elevator, repeat the process or brush the lashes up lightly in multiple layers.

(Optional) Extra layer of mascara 5.

Want extra volume or fixation? Then you can apply a thin, second coat of mascara after curling. Just make sure the brush is not too hot if you do this right after.

Why choose an electric eyelash curler instead of a regular one?

A traditional eyelash curler works by mechanical force. You place your lashes between them and press together briefly. While this works, it can also cause eyelash breakage, especially if you squeeze the tongs too hard or have already applied mascara.

An electric eyelash curler, on the other hand:

Treats your lashes with heat instead of pressure
Provides a more gradual and natural curl
Is kinder to sensitive eyes and brittle lashes
