How to Apply Cat Eye Gel Polish: The Magnet Technique

Cat eye gel polish is one of those effects clients want to see straight away: a glowing stripe of light that moves as the hand moves. For a clean, deep result, layer thickness, timing and the right magnet are what count. Here you will learn how the magnet technique works, how cat eye differs from reflection and which mistakes to avoid.

What is cat eye gel polish?

Cat eye gel polish (often also called “cat’s eye”) contains fine magnetic particles. As long as the polish is not yet cured, these particles can be moved with a magnet and gathered in one place. That is where the light collects – creating the typical stripe reminiscent of a cat’s eye. Depending on the magnet shape and position, you can create a narrow line, a wide shimmer, a diagonal gradient or a deep, multidimensional effect.

Important: the effect has to be created while the polish is still liquid and then cured in the lamp immediately . Only then are the particles fixed in place.

Cat eye or reflection: the key difference

In the salon, the two effects are often confused because both sparkle. In application, however, they differ fundamentally:

Feature	Cat Eye	Reflection
Particles	magnetic	reflective, not magnetic
Magnet needed?	Yes, for the light stripe	No – no magnet step
When is it visible?	Always; the stripe moves with the angle of the light	Mainly in direct light, e.g. flash
Curing	immediately after magnetising	just like a classic gel polish

A reflection gel polish such as the LUNA moon Gellack N°220 is therefore simply applied and cured. Holding a magnet over it does nothing – the particles do not react to it. So always check the product details before the treatment: if it says “cat eye” or “magnetic”, you need the magnet. If it says “reflection”, you work without it.

Which magnet do you need?

The shape of the magnet determines the shape of the effect. To start with, a magnet with a clear edge for the classic line is enough. If you want to offer more variations, work with several shapes:

• Double-sided magnet: The LUNA moon Cat-Eye Magnet doppelseitig works with attraction and repulsion – so you can create both sharp stripes and soft, diffuse effects.
• Magnet for depth effects: The DNKa’ Cat-Eye Magnet 5D is placed under the finger, directly beneath the nail plate. This creates a deep, multidimensional shimmer.
• Ball magnet: The ADORE Cat-Eye Magnet Ultra with balls is suitable for creative patterns and spots of light.

Step by step: cat eye with the magnet technique

1. Prepare the nail: Work on the cuticle, lightly buff the nail surface, remove dust and degrease the nail plate.
2. Apply the base: Apply a thin layer of base coat and cure in the lamp according to the manufacturer’s instructions.
3. Optional dark underlayer: For more depth, apply and cure a dark colour layer (e.g. black or a dark shade). With transparent cat eye polishes, the underlayer changes the effect significantly.
4. First cat eye layer: Apply the cat eye gel polish, for example DNKa’ Gellack Cat’s Eye #0017 Bohemian, thinly and evenly. Mix the bottle well beforehand so that the particles are evenly distributed.
5. Apply the magnet: Hold the magnet just above the nail without touching the polish and keep it still for a few seconds until the stripe has formed. With the 5D magnet, place it under the finger instead.
6. Cure immediately: Put the finger straight into the lamp. The longer you wait, the more the particles spread out again and the stripe becomes blurred.
7. Second layer: For more colour depth, apply a second thin layer, apply the magnet again – in the same position or with a different magnet shape – and cure immediately.
8. Seal: Seal with a glossy top coat, cure and remove any sticky layer.

Typical mistakes and how to avoid them

Layer too thick

In a thick layer, the particles have too much room, and the stripe becomes wide and blurred. A layer that is too thick also cures less well. Two thin layers are better than one thick one.

Waiting too long before curing

The most common mistake: magnetising first, then quickly painting the next finger. During this time, the particles drift back. So work finger by finger or on two nails at most at the same time.

Magnet touches the polish

If the magnet gets too close, it leaves marks in the still-liquid layer. Keep a small, even distance and guide the magnet calmly.

Bottle not mixed

Magnetic particles settle at the bottom. Without mixing, the effect looks weak or patchy.

Unintentional matte top coat

A matte top coat noticeably dulls the light stripe. For the classic cat eye look, a glossy finish is the right choice – matte only if you deliberately want a velvety look.

Using a magnet on reflection

As described above: reflection gel polish is not magnetic. If “nothing happens” despite the magnet, it is usually because a reflection polish is being used instead of a cat eye polish.

Pro tips for more impact

• Choose the direction deliberately: A diagonal stripe has a lengthening effect; a central stripe looks classic and elegant.
• Combine magnets: Start with a depth magnet, then create a clear line on the second layer.
• Work consistently: Hold the magnet at the same angle on all nails so the overall look is harmonious.
• Keep magnets clean: After the treatment, remove gel polish residue from the magnet with a lint-free wipe.

FAQ on cat eye gel polish

Does reflection gel polish need a magnet?

No. Reflection gel polish contains reflective but not magnetic particles. You apply it and cure it as usual – there is no magnet step.

How long do I hold the magnet over the nail?

A few seconds are usually enough for the stripe to form visibly. What matters is that you cure straight afterwards without a pause.

Can I use cat eye without a magnet?

Yes. Without a magnet, the particles spread evenly and you get a fine, all-over shimmer instead of a stripe of light.

Why is my cat eye stripe blurred?

Usually the layer is too thick, the magnet is too far away, or too much time has passed between magnetising and curing.

Conclusion

With thin layers, the right magnet and immediate curing, you will achieve the cat eye effect reliably. Above all, remember: cat eye is magnetic, reflection is not. You will find matching colours in our category Gel Polish, and the matching magnets directly with the linked products.
