Gel vs. Semi-Permanent: What's the Difference and Which Manicure Should You Choose?

Gel or Gel Polish? That's THE question you inevitably ask yourself before booking a salon manicure or splurging on an at home kit. Wear time, shine, removal, effects on the nails… Let's compare the two techniques to see things more clearly and help you make the right choice, based on your profile and what you're looking for.

 

In short: gel or gel polish?

 

Gel is the most popular solution if you want an extra long lasting manicure (up to a month), with a glossy, ultra domed finish. The flip side: this technique requires a fairly long in salon application, and removal involves an electric file, with the risks that carries for the nail.

• Gel Polish offers a simpler manicure routine that's easier and quicker to apply and remove yourself with an acetone based remover. Less durable than gel, it still delivers mirror shine and intense color for up to 3 weeks.
• For an easy, radiant, long lasting and risk free manicure for your nails, Green Flash™ is the ideal alternative, well worth trying if you haven't already.

 

Understanding the basics

Before we get into the differences between gel polish and gel, let's start by clearly defining the products in question.

What is Gel Polish?

Emerging in the 2010s, Gel Polish shook up the nail polish world by promising a long lasting manicure that's just as easy to apply as classic nail polish. A revolution made possible by a formula based on photosensitive resins and monomers that cures under a UV or LED lamp to form a hard, resistant film. The result: a radiant color, intense shine and a natural domed finish that lasts two to three weeks.

Application is very simple and requires no particular technical skill. Gel Polish is fluid and goes onto bare, prepped nails with a few brushstrokes, just like traditional nail polish. Application is done in 4 layers, each of which needs to be cured under an LED/UV lamp:

• 1 layer of base coat
• 2 thin layers of color
• 1 layer of top coat

 

Finally, removal is done by filing, buffing, or with an acetone based remover.

While it has plenty of advantages that explain its success, Gel Polish also has its limits. Heavy use can cause sensitization and allergies, caused by ingredients that carry risks for human health, such as methacrylate monomers (HEMA and DIHEMATMHDC) and other substances classified as CMR (banned under European regulations for cosmetics made and sold in the EU). Not to mention the nail weakening caused by harsh removal.

Pros and cons of Gel Polish:

✅ Simple, quick application and removal, done yourself
✅ 2 to 3 weeks of wear
✅ Intense color, mirror shine
❌ Acetone based removal
❌ Risk of sensitization

What is gel / acrygel?

Gel is a thick resin whose main purpose is strengthening natural nails. Color here is secondary. Its viscosity lets you work on the nail's structure to hide imperfections and add volume and length, with nail extensions for example. Gel nails offer durability of up to 4 weeks, well beyond Gel Polish. An ideal choice for anyone who wants to stop biting their nails or protect broken or damaged nails while still showing off a flawless manicure.

Applying gel nails is a longer, more complex technique, and is most often done in a salon by a nail technician. A gel manicure is done in 3 steps:

• Applying a base gel
• Shaping the builder gel
• Finishing with a top gel

 

Some gels combine all 3 steps into a single product. The different layers dry under a UV/LED lamp for builder gels, or air dry for acrylic gels.

Removal is one of the weak points of UV gels. Some soak off UV gels can be removed with an acetone based remover. For most gels, though, removal is usually done with an electric file or a nail file, which can cause lasting damage to the nail plate. Finally, gel formulas are mostly made from petrochemical ingredients, which, with frequent use, can cause sensitization and/or allergic reactions.

Pros and cons of gel:

✅ 3 to 4 weeks of wear
✅ Intense shine, domed effect, nail reinforcement
❌ Application and removal in salon
❌ Removal by buffing
❌ Risk of sensitization

Which technique best suits your needs?

Short, healthy nails: Gel Polish

Do you have short, healthy nails and mainly want to enjoy a pretty, glossy color that lasts? Gel Polish is your best option. Applied to properly prepped natural nails, it enhances them without trying to change their length or shape. It's the perfect match if your goal is above all a colorful, durable manicure with a glossy finish, while keeping a fairly natural result.

Fragile nails or wanting length: gel

Do you dream instead of gaining length or changing the shape of your nails? This is where a gel manicure stands out. Unlike simple Gel Polish, gel lets you build and shape the nail to achieve a length or structure that wouldn't be possible with the natural nail plate alone.

If you have soft or brittle nails where polish chips within days, or you want to space out your manicure appointments as much as possible, gel / acrygel is an option worth considering to reinforce your nails and protect them as they grow out. However, if your nails are particularly weakened, it's best to strengthen them with a course of suitable treatments before considering any new application.

Quick session or small budget: Gel Polish

Do you like changing color often, or are you looking for a manicure that's easy to fit into a busy schedule? Between gel and Gel Polish, the latter is generally the simplest solution when speed is the priority.

Application requires no particular technique: careful prep, a base coat, a color and a top coat cured under a lamp, and that's it. The process is therefore easier to do at home with the right equipment, with no need to visit a nail technician.

Budget wise, Gel Polish can also be a smart choice for anyone who wants to become self sufficient. With a complete Gel Polish kit, including the lamp and routine essentials, you can do manicure after manicure at home without breaking the bank. An investment that pays for itself quickly!
