Cat-Eye Nails: How to Do Magnetic Gel Step by Step
Cat-eye nails use a gel polish filled with tiny magnetic particles. You paint it on, hold a magnet close to the nail for about 5 to 10 seconds to pull the shimmer into a line or glow, then cure immediately so the effect is locked in.
Updated:
- Cat-eye gel contains metallic particles that move toward a magnet.
- Hold the magnet about 2 to 5 mm above the nail for 5 to 10 seconds, without touching it.
- Cure right away after using the magnet, or the particles start to spread out again.
- A black or dark base gives the most dramatic effect; a sheer base gives a soft glow.
- Moving the magnet around the nail creates the velvet cat-eye look.
What you need
- Gel base coat and gel top coat
- Magnetic cat-eye gel polish
- A nail magnet (a strong, flat-ended or double-ended magnet works best)
- An LED or UV lamp
- Optional: black or colored gel for the base layer
- File, buffer, cuticle pusher and alcohol wipes
Shake or roll the cat-eye bottle before every use. The magnetic particles settle at the bottom, and a well-mixed gel gives a much stronger effect.
Magnet placements and effects
| Effect | How to hold the magnet |
|---|---|
| Classic line | Parallel to the nail, centered, for a sharp stripe of light |
| Diagonal | At an angle across the nail for a slanted beam |
| Wide glow | Hold it further away for a softer, broader band |
| Velvet | Move the magnet slowly around all sides of the nail so the shimmer spreads evenly |
| French cat-eye | Hold it near the tip to concentrate the shine at the free edge |
| Starburst | Use the pointed end of a magnet near the center of the nail |
Choosing your base
Cat-eye gel is often semi-sheer, so the color underneath changes the final look.
- Black base: the deepest contrast and the most three-dimensional effect.
- Same color base: a rich, tonal look, such as burgundy cat-eye over burgundy gel.
- Sheer nude or milky base: a soft, delicate moonstone glow for everyday wear.
- No base color: cat-eye directly over the base coat for a subtle, glassy shimmer.
Troubleshooting
- Weak or blurry line: the gel was not mixed, the magnet was too far away, or you waited too long before curing.
- Line in the wrong place: repaint the layer while uncured, or apply the magnet again before curing.
- Uneven between nails: do one nail at a time: paint, magnet, cure, then move to the next.
- Magnet touched the gel: wipe the magnet clean, fix the surface with a brush and use the magnet again, holding it slightly higher.
Safety and removal
Work in a ventilated room and keep uncured gel off your skin and cuticles, because repeated skin contact can cause allergic reactions. If you notice itching, redness or swelling, stop using the product and see a professional. Remove cat-eye gel the same way as any gel: file off the top coat, soak in acetone for about 10 to 15 minutes, and gently push off the softened gel. Never peel it off.
Step by step
- Prep the nails. Shape the nails, push back the cuticles, lightly buff off the shine and wipe with alcohol.
- Apply base coat and cure. Paint a thin layer of gel base coat, keeping it off the skin, and cure for the time your lamp recommends.
- Add a base color (optional). For a dramatic effect, apply a thin layer of black or colored gel and cure. Skip this step for a sheer moonstone look.
- Mix and apply cat-eye gel. Roll the bottle for 20 to 30 seconds, then apply a thin, even coat of cat-eye gel to one nail.
- Use the magnet. Hold the magnet about 2 to 5 mm above the nail for 5 to 10 seconds in the position that gives your chosen effect. Do not touch the gel.
- Cure immediately. Put the nail under the lamp straight away and cure fully. A quick cure locks the particles in place before they drift.
- Add a second coat. Repeat the cat-eye layer and the magnet step for more depth, then cure again.
- Top coat and finish. Seal with gel top coat, cap the free edge and cure. Finish with cuticle oil around each nail.

FAQ
Can I do cat-eye nails with regular polish?
Magnetic regular polishes exist and work in a similar way, but the effect is usually softer and dries less predictably. Gel gives the sharpest and longest-lasting cat-eye because you can cure it the moment the line looks right.
Why is my cat-eye effect not showing?
The most common reasons are that the gel was not mixed, the magnet is too weak or too far away, or you waited too long before curing. Shake the bottle well, hold the magnet close, and cure immediately.
What is velvet cat-eye?
Velvet cat-eye spreads the magnetic shimmer across the whole nail instead of a single line. You get it by moving the magnet slowly around the sides and tip of the nail, which gives a soft, plush, fabric-like glow.
How long do cat-eye nails last?
Like other gel manicures, cat-eye nails usually last about two to three weeks. Capping the free edge with top coat helps prevent chips.
What kind of magnet do I need for cat-eye nails?
Any strong nail magnet works for a classic line. Flat-ended magnets make straight lines, while double-ended or pointed ones make starburst and diagonal effects. Some cat-eye gels come with a magnet, but a stronger separate magnet gives sharper results.
