What is gel nail polish?

Gel nail polish is a hybrid formula that combines the fluidity of regular polish with the strength of gel. It cures under a light LED lamp in just seconds, forming a thin, smooth, and glossy finish that stays in place for days without chipping. Unlike traditional regular polish, gel provides a long-lasting shine that lasts longer than ordinary nail varnish.

Gel nail polish doesn’t add bulk, keeping the natural look and feel of the nail while offering a top-quality finish. It also doesn’t require professional tools or techniques, making it ideal for a salon-quality polish from the comfort of your home. Whether you're after a unit purchase or a larger kit, gel polish is perfect for easy wear and extended shine.

How to choose a gel nail polish ?

When choosing a gel nail polish, the key things to consider are the formula, the wear, the comfort of application, and the removal process. A good gel polish should keep your nails looking healthy, feel comfortable to wear, and come off easily — without scraping, filing, or causing damage.

Green Flash™ stands out for its formula, which is up to 84% plant-based, vegan, and 12-free, removing harmful ingredients commonly found in traditional gel polish. It offers up to 12 days of vibrant wear and shine, and can be removed in just 1 minute with a gentle, acetone-free remover.

If you're new to gel nail polish at home, the Green Flash™ kit includes everything you need for an easy, salon-quality manicure — all from your bathroom table. The KeraHCE+ technology helps to strengthen the nail beneath the color, making it ideal for a long-wear gel effect while keeping the nail smooth, strong, and healthy.

How long does gel nail polish last ?

Most gel nail polish lasts between 7 and 14 days, depending on your nail type and how you apply it. Preparation is key: clean, dry nails, thin coats, and proper curing under your LED lamp will give the best results.

Newer LED-cured formulas provide long-lasting wear while still being gentle on the nail. These formulas are designed to prevent drying, peeling, or weakening the nail plate over time. If you’re looking for a more affordable option, you can find individual units or kits with everything you need for a flawless finish.

How to apply and remove gel nail polish ?

Application follows three simple steps: base coat, color, and top coat — with each layer cured under an LED lamp. Thin coats give the best, smoothest, and most even result, ensuring a flawless shine.

Removal depends on the formula. Traditional gel polish often requires filing or prolonged exposure to acetone. With Green Flash™, removal is quick and gentle: simply apply a cotton pad soaked in a gentle remover, leave it on for a minute, and the polish lifts away — no scraping, no damage. The ease of removal makes it an excellent choice for both beginners and experienced users.

What colors and styles are available in gel nail polish ?

Gel nail polish comes in a wide range of colors, so you can choose the perfect shade for any occasion. Neutral tones offer a clean, polished look that works with everything, while reds remain timeless and elegant.

For something more contemporary, try blues, greens, and purples — bold colors that bring a trendy touch to your nails. Shimmers and metallics add subtle dimension for evening looks, making gel polish the perfect choice for a sleek, long-lasting shine.

The French manicure continues to evolve, from classic white tips to soft pastels or modern bold contrasts. For the summer, warm and sun-kissed shades look beautiful on both hands and toes. The long-wear finish of gel nail polish makes it a favorite for vacations, beaches, and travel — it stays smooth and glossy, even after days in the sun and saltwater.

How to choose your gel nail polish?

Choosing a gel nail polish is no longer just about picking a shade or following a trend. Today, people are looking for the perfect balance between wear, formula and ease of use. A good gel nail varnish should offer optimal adhesion without weakening the nail, while still being easy and quick to remove.

With Green Flash™, we offer a vegan formula made from up to 84% plant based ingredients, designed to respect your nails while delivering a professional finish.
In line with European regulations, Green Flash™ is free from endocrine disruptors such as toluene, DBP and formaldehyde, as well as other controversial ingredients like methacrylate monomers including HEMA.

This new generation gel nail polish combines gentleness with performance.
Thanks to the patented KeraHCE+ technology in the Green Flash™ vitamin enriched Base Coat, the natural nail is strengthened beneath the colour, helping your manicure last longer.
Another key benefit is removal. Green Flash™ gel polish can be removed without acetone or filing, simply using a gentle remover with a peel off effect.

How long does a gel nail polish?

The staying power of gel nail polish depends on nail preparation, application technique and the formula used. When applied to a well prepared nail, gel polish adheres better. Applied in thin layers and cured properly under a UV or LED lamp, it keeps its shine and strength for 10 to 14 days, depending on your nail type and how often your hands are exposed to water or household products.

With Green Flash™, you can tailor how long your manicure lasts to suit your needs:

  • A natural manicure with mirror like shine for up to 12 days using the standard Green Flash™ routine with Base Coat, colour and Top Coat.
  • A plump gel effect finish with intense shine and strength for up to 21 days using the Xtrem Flash™ routine with Base Coat, Green Flash™ colour and Xtrem Flash™ Top Coat.

Unlike traditional gel systems, the natural nail remains protected and removal is quick and gentle, with no acetone or filing required.

What are the characteristics of semi-permanent nail polishes?

Green Flash™ gel nail polish uses LED curing technology to create a smooth, flexible and glossy film, delivering a professional finish from the very first application.

Unlike regular polish, gel polish does not air dry. It cures under a UV or LED lamp, which ensures better resistance, longer wear and a radiant finish. Thin layers give a natural and elegant result, perfect for both manicures and pedicures.

Beyond performance, this formula also acts as active care.
The patented KeraHCE+ technology helps strengthen the natural nail beneath the colour. The plant based formula also allows for gentle removal without acetone or filing, preserving the nail’s integrity. Each application becomes a moment of care, combining long lasting performance with the pleasure of beautiful gel nail polish colours.

What are the drawbacks of semi-permanent nail polish?

While loved for its long wear and high-shine finish, traditional semi-permanent nail polish has long been linked to a trade-off: longer-lasting colour often came at the expense of nail health. Three downsides come up most often among semi-permanent manicure users:

  • Aggressive nail prep: traditional formulas require intensive filing to ensure proper adhesion of the Gel Polish. Over time, the nail becomes thinner, loses flexibility and becomes more sensitive to impact.
  • Even more aggressive removal: because it is highly resistant, traditional Gel Polish must be removed using an electric nail drill, a coarse nail file and/or an acetone based remover. These methods can damage the nail plate and disrupt healthy nail growth.
  • Nails become weaker over time: repeated applications of traditional Gel Polish, without breaks or nourishing care in between, tend to weaken the nails. Lacking hydration and essential nourishment, nails can become brittle, soft or start to split.

Traditional gel nail polish vs. Manucurist: What’s the difference?

Traditional gel nail polish is often designed to maximise durability and resistance, which can make removal more difficult and weaken the nail over time. Acetone or electric filing is commonly required, especially with formulas close to gel or acrylic systems.

Green Flash™ takes a different approach. Its formula focuses on flexibility and nail health, while still delivering satisfying wear. The real innovation lies in the removal process. The polish can be removed easily without damaging the nail or the surrounding skin.

This makes it an ideal choice for anyone looking for a good gel nail varnish that performs well, suits regular use and respects nail health.

How to easily apply and remove Green Flash™ gel nail polish?

Creating a gel nail polish manicure at home is simple with the Green Flash™ routine. The application follows three steps: Base Coat, colour and Top Coat. Each layer is cured under an LED lamp, ensuring fast drying and an even finish.

Using an LED lamp is essential for proper curing, optimal wear and a professional result from the very first application.

When it comes to removal, the difference from traditional gel polish is significant. There is no need for filing, drilling or acetone.
The polish can be removed quickly using a gentle remover with a peel off effect, helping preserve the natural nail and prevent damage.
