What Is Gel Nail Polish? Everything You Need to Know

Gel polish is the most popular way to do your nails at home, but if you're new to it, the basics can feel a little mysterious. What actually is gel? How is it different from the polish you grew up with, and why does it last so much longer?

As the UK's No.1 at-home gel nail brand, this is what we do all day. Below, we'll walk you through exactly what gel polish is, the different types, how it compares to regular polish and acrylics, and how to apply it for salon-quality results that last up to 3 weeks. Whether you're a complete beginner or just filling in the gaps, you're in the right place.

At a glance:

• What it is: A polish that sets hard under an LED lamp rather than air-drying, for chip-free wear up to 3 weeks.
• Why people love it: Durable, high-shine, beginner-friendly, and gentle on nails when applied and removed correctly.
• The Mylee difference: Every formula is vegan, HEMA-free and TPO-free, with 250+ shades to choose from.

What is gel nail polish?

Gel nail polish is a polish that stays liquid until it's "cured" (set and hardened) under an LED lamp, rather than drying in the air like traditional polish.

The science behind it is simple enough. Gel is made from monomers and oligomers, small molecules that bond together when exposed to an LED lamp or led light, locking your colour into a tough, glossy finish.

So here's the thing: if your polish air-dries and doesn't need to be cured under a lamp, it isn't real gel. You may have seen "no lamp needed" gels from other brands, but without curing, the formula can't form that hard, bonded finish, which means it won't wear like true gel. It's closer to a regular polish with a gel-like name, and it won't give you the chip-free wear you're paying for. Real gel cures. That's what delivers up to 3 weeks with no chips, smudges or dents.

At Mylee, every gel formula is also vegan, HEMA-free and TPO-free, meaning it's made without two ingredients increasingly restricted by regulators and linked to skin sensitisation. It's salon-quality performance, formulated with your nail health in mind.

The different types of gel

Gel polish comes in a few different forms, and you'll find each of them in the Mylee range. Here's how they break down.

Pro tip: If you're just starting out, you don't need all of these. A base coat, a colour, a top coat and a lamp will get you a beautiful, long-lasting manicure. The rest are there for when you want to explore length, strength or nail art.

Gel vs regular polish: what's the difference?

The differences come down to how each one dries, how long it lasts and how it wears. Here's the quick comparison.

Gel manicures are lasting longer than regular nail polish because each layer is cured under the lamp.

The headline difference is curing. Regular polish dries in the open air, which is why it takes its time and chips so easily. Gel doesn't dry at all until it's cured, so there's no rushing your application, and no smudging your nails the moment they're "dry".

That curing step is also what gives gel its durability. Once set under the lamp, your colour is locked in, so a Mylee mani stays flawless for up to 3 weeks where regular polish would already be chipping.

Gel vs acrylic nails: what's the difference?

Acrylics and gels are often confused, but they're made and worn quite differently. Acrylics are created by mixing a liquid monomer with an acrylic powder, which forms a hard layer as it sets.

That makes acrylics thicker, stiffer and less flexible than gel, and they usually need more filing and buffing of the natural nail to adhere, which can be harsher over time. Because they're rigid, they can also be more prone to snapping.

Gel is the gentler, more natural-feeling option. It's thinner and more flexible, so it moves with your natural nail and tends to feel more comfortable, while still giving you length and strength when you want it through builder gel or tips.

Can you use gel polish on natural nails?

Yes, and it's exactly what gel is designed for. As long as you apply a base coat (or builder gel) underneath your colour, your natural nails will wear gel beautifully.

In fact, gel can actively help. A gel overlay protects shorter or weaker nails as they grow, which makes it a favourite for nail biters or anyone trying to break a nail-biting habit. It's a protective layer that lets your natural nails grow out underneath.

One important note: don't apply gel over a damaged nail. If your nails are weak, thin or bendy, give them a recovery period first with a treatment like our air-dry Double Bond Nail Treatment, then build back up once they feel stronger and use gel as a treat for weak nails once they've recovered enough for application.

How to apply gel polish

Applying gel is a simple, repeatable process once you know the steps. You can't go straight in with colour, the prep is what makes it last, so follow our method for the best results.

Step 1. Prep & prime
File your nails to shape, then gently remove the shine from the nail plate with a Mylee Buffing Block so the gel can grip. Wipe each nail with a dash of Mylee 2-in-1 Nail Prep & Wipe on a Lint-Free Wipe to remove any oils. If you're prone to lifting, apply the Mylee Dehydrator followed by the Mylee Acid-Free Primer.

Pro tip: Remove any gel you get on your skin before curing, using an angled brush around the cuticles and nail edges. It keeps your finish clean and helps eliminate the risk of skin reactions.

Step 2. Base coat & cure
Apply a thin layer of Mylee Base Coat and cure for 60 seconds under your Mylee LED Lamp.

Step 3. Colour & cure
Brush on your favourite Mylee Gel Polish shade and cure for 60 seconds. Build up the opacity in thin coats, curing each layer, for a smooth, even finish. Don't forget to cap the free edge by running the brush along the very tip of your nail to seal off the colour.

Pro tip: Capping the free edge wraps the gel around the tip of the nail and is one of the simplest ways to prevent chipping and lifting. Thin layers matter too, thick coats are slower to cure and more likely to wrinkle.

Step 4. Top coat, cure & finish
Apply your Mylee Top Coat and cure for 60 seconds. With a regular top coat, wipe away the tacky layer afterwards with Nail Prep & Wipe on a Lint-Free Wipe, or switch to Mylee No-Wipe Top Coat to skip this step. Wash your hands, massage in Mylee Sweet Almond Nail & Culticle Oil, and enjoy your salon-quality mani for up to 3 weeks.

Do you need a lamp to use gel polish?

Yes. Gel polish only sets when it's cured under an LED lamp, so a lamp is essential, not optional.

Without curing, the gel stays liquid, you can't build your layers, and you won't get that 3-week wear. This is the fundamental difference from regular polish, which dries in the air.

Every Mylee gel cures in 60 seconds under our LED lamps (99 seconds for our high-pigment Super Pigment Builder Gel). Once your top coat is cured, your nails are done, no drying time, no waiting around waving your hands in the air. If you'd like to understand the technology, our full guide to UV vs LED nail lamps explains why LED is the modern standard.

Are gel nails bad for you?

It's one of the most common questions we hear, and the honest answer is no, gel polish isn't bad for your nails when it's applied and removed correctly. Gel nails can cause allergic reactions in some individuals, especially if uncured product contacts the skin.

Worn properly over a base coat, gel protects the natural nail from daily knocks and lets it grow out underneath. Most of the damage people associate with gel actually comes from removal, specifically picking or peeling it off, which strips the top layers of the natural nail.

The fix is simple: proper application and gentle removal help avoid damage to the natural nail, so never pick or peel and always remove gel using the method below. Do that, and gel is a safe, nail-friendly way to wear colour.

How to remove gel polish safely

Gentle, patient removal is everything. Here's the safe four-step method, and we've got video tutorials and a full removal guide on the blog too.

Step 1. Break the top coat seal
Buff the surface of your gel using the 180-grit side of a Mylee Nail File to remove the shine. This is what lets the remover penetrate, so use firm, controlled strokes across each nail. There's no need to file down the colour at this stage.

Step 2. File down the bulk (extensions only)
If you're removing Builder Gel, Magic Extender Gel or Fix 'N' Flash Tips, file down around 90% of the bulk first so the remover can reach the base layers more quickly. Trim long extensions down before you start to speed things up.

Step 3. Soak off with remover
Soak a lint-free pad in Mylee Gel Remover or 100% Pure Acetone, place it on the nail and secure with a foil wrap or our Soak Off Clips. Leave for 10 to 15 minutes. (Prefer to skip acetone? Our Gel Remover is a gentler alternative.)

Step 4. Wait, remove and nourish
After 15 minutes, firmly pull the pads off. The gel should look lifted or crinkled, ready to come away. Gently push it off with a scraper, and if any resists, re-soak rather than forcing it. Finish by washing your hands and massaging in Sweet Almond Nail & Cuticle Oil to rehydrate.

Pro tip: The golden rule is patience. If the gel resists, it needs more soaking, never force it. That's what protects your natural nails and helps reduce the risk of breakage.

Can you infill gel polish?

Yes, and it's a brilliant way to refresh your nails without a full removal, as long as your manicure is built on builder gel or Magic Extender Gel.

Infilling means "filling in" the regrowth. As your natural nail grows, a gap appears at the cuticle; infilling tops that up so your nails look freshly done without removing the whole set. It's gentler on the natural nail and quicker than starting over.

Looking after your gel nails

A few simple habits will keep your set looking fresh and your natural nails healthy underneath.

• Moisturise daily. Apply cuticle oil daily: it keeps cuticles soft, supports growth, and helps stop your gel lifting at the edges.
• Wear gloves for chores. Harsh cleaning products and hot water dry out nails and weaken the gel bond, so protect your hands when cleaning.
• Never pick or peel. Always remove or infill properly. Picking takes layers of your natural nail with it.
• Refresh at the right time. You'll know it's time when you can see regrowth between your cuticle and the gel, usually every 2 to 3 weeks.

And one myth worth busting: you don't need to give your nails a routine "break" to let them breathe. Nails have no pores, so they don't breathe, and healthy nails can wear gel continuously. We've covered this in full in our guide on taking a break from gel nails.

If your nails feel weak after repeated wear, a short pause can help reduce breakage.

The takeaway

Gel polish is simply a polish that cures hard under an LED lamp instead of air-drying, unlike a regular manicure, and that one difference is what gives you smoother application, a high-shine finish and chip-free wear for up to 3 weeks. Applied and removed correctly, it's a safe, nail-friendly way to get salon-quality results at home.

With 250+ shades and finishes to choose from, all vegan, HEMA-free and TPO-free, there's a Mylee gel for every mood and occasion. Explore the range and start your first set.

FAQs

Is gel polish different from normal nail polish?

Yes. Gel is thicker, applies more smoothly, and must be cured under an LED lamp to set, while regular polish air-dries in the open. The payoff is wear time: gel lasts up to 3 weeks chip-free, where regular polish chips within about 7 days.

How long do gel manicures last?

A Mylee gel manicure lasts up to 3 weeks. Most people refresh or infill every 2 to 3 weeks, depending on how quickly their nails grow and how the gel is wearing, though wear time can also vary with application quality, daily use, and different nail techs or salons. That's far longer than regular polish, which typically lasts around 7 days.

How long does gel polish take to dry?

Gel doesn't air-dry, it cures under a lamp in seconds. Each layer cures in 60 seconds under a Mylee LED lamp (99 seconds for Super Pigment Builder Gel). Once your top coat is cured, your nails are ready right away, with no drying time.

How long does a gel manicure take?

It depends on the look. A simple all-over colour can take around 30 minutes including prep, while dramatic length or detailed extension work can push the appointment toward an hour or more. The good news is there's no drying time to wait through at the end.

Do you need a lamp to cure gel polish?

Yes. Gel polish only sets when cured under an LED lamp, so a lamp is essential. Every Mylee gel cures in 60 seconds under our LED lamps, and our gels and lamps, like opi systems, are designed and tested together for a complete, even cure every time.

Is gel polish safe for your nails?

Yes, when applied and removed correctly. Worn over a base coat, gel protects your natural nail as it grows. The damage people blame on gel almost always comes from picking or peeling it off, so gentle, proper removal is the key to keeping your nails healthy.
