Gel nails have become the professional standard for long-lasting color and a flawless finish. But what makes them different from acrylics or regular polish? And why do some gel manicures last for weeks, while others peel within days?
This guide breaks down what gel nails are, how they work on a chemical level, and why proper technique is essential for results that last.
What Are Gel Nails?
Gel nails are a system that uses light-reactive gel products cured under UV or LED lamps to form a hardened, high-gloss coating. Typically applied in three layers—base, color, and top coat—each layer is cured to create a durable finish that resists chipping and lifting.
There are two main types of gel:
• Soft gel (e.g., gel polish) – Delivers color and shine over the natural nail.
• Hard gel – Can be used to sculpt nail length or add strength.
Gel systems require careful prep and precise curing, but in return offer clients durability, comfort, and aesthetic consistency.
How Gel Nails Work – The Chemistry Behind the Shine
At the core of a gel manicure is a chemical process called photopolymerization. Here’s what happens:
1. Application – The gel contains oligomers and photoinitiators.
2. Curing – Under UV or LED light, the photoinitiators activate, causing the oligomers to link together.
3. Hardening – The result is a cross-linked polymer structure that bonds to the nail, creating a strong yet flexible surface.
Each layer must be applied evenly and cured completely to avoid lifting, wrinkling, or undercuring—one of the most common causes of sensitivity and poor wear.
“We always tell our students that gel nails are only as strong as your prep and your lamp. You can’t rush the process — when you understand the chemistry, everything clicks. That’s the difference between short-term results and long-term client loyalty.”
— Charli Jepson, Head of Education at Glitterbels
Common Mistakes That Lead to Gel Nail Failure
Poor results usually come down to process, not product. The most frequent issues include:
• Skipping prep – Natural oils or residue stop the gel from adhering properly.
• Over-applying – Thick layers don’t cure evenly and can cause heat spikes or wrinkling.
• Low lamp power – Under-curing weakens the final manicure and increases allergy risks.
Training and consistency are key. With the right tools and education, gel nails can be one of the most reliable systems a nail tech offers.

When to Use Nail Polish Instead of Gel
While gel and acrylic provide extended wear, nail polish is still a smart option for quick services or clients who love to change colors frequently. And as we always say—gel and acrylic should only be applied by trained professionals. Nail polish, though? Anyone can use it.
The new Glitterbels Nail Polish Collection was created to offer:
• Fast air-drying performance
• Bold pigmentation and smooth application
• Shades that complement our gel line
• A great solution for natural nails and express services
It’s varnish — but elevated. Perfect for mobile techs, salons, and even DIYers who want a high-end result without a lamp.
FAQs About Gel Nails
Q: What are gel nails made of?
A: Gel nails are made from light-reactive polymers—specifically oligomers and monomers—that harden under UV or LED light.
Q: How long do gel nails last?
A: Usually 2–3 weeks, though it depends on the client’s aftercare, how well the nails were prepped, and how they use their hands.
Q: Are gel nails safe?
A: Yes—when applied and cured correctly. Under-curing or repeated exposure to uncured product can cause sensitivity or allergic reactions. For clients with sensitivities, Glitterbels offers a range of HEMA-free products, including gel polish and Builder Gel.
Q: Can you remove gel nails at home?
A: Soft gel (like gel polish) can be removed with acetone and wraps. Hard gel typically needs professional filing to avoid damage. We always recommend professional removal.
Q: Is gel better than polish or acrylic?
A: Each has its place. Gel is flexible and long-lasting. Acrylic is sculptable and ultra-durable. Nail polish is ideal for quick, easy changes.
