Gel nail varnish has become a staple in the nail industry, with its long-lasting wear, intense shine, and wide range of colours and finishes. But what is it made of? Gel nail varnish is formed of methacrylate compounds and photoinitiator compounds like benzoyl peroxide that don't dry but instead adhere to the nail when exposed to UV light. It also contains plasticizers, which give it its strong but flexible nature, and inorganic or organic pigments.

What You'll Learn
Gel nail varnish is cured under UV or LED light
The curing process is what distinguishes gel nail polish from regular nail polish. Gel nail polishes are cured under UV or LED light, forming a hard, durable layer on the nails. The curing process involves placing the nails under a special lamp, which emits UV or LED light. This light triggers the polymerisation of the gel polish, causing it to harden and form a strong, chemical-resistant coating.
Gel nail polishes are made up of acrylic monomers and oligomers that bond together when exposed to UV or LED light. This process, known as curing, transforms the once-liquid gel into a hard, chip-resistant coating. Unlike regular nail polish, which dries naturally and can chip or peel easily, gel polishes require a curing lamp to harden and set. The curing process typically takes less than a minute, and the resulting manicure can last for several weeks without chipping or peeling.
The type of curing light used, whether UV or LED, depends on personal preference and the specific gel polish being used. LED lights are generally considered safer for the skin, as they do not emit UV rays. However, it is important to note that the UV lights used for curing gel nail polish are not the same as those used in tanning beds, which can be harmful. To protect the skin from potential harm, it is recommended to apply sunscreen or wear special gel manicure gloves during the curing process.
The curing process for gel nail polish typically involves multiple steps. First, the nails are cleaned, trimmed, and shaped. A base coat may be applied to protect the natural nail from discolouration. Then, the gel polish is applied in thin coats, with each coat cured under the UV or LED light. This process is repeated until the desired number of coats is achieved, ending with a top coat for added shine and protection. After curing the final coat, there may be a sticky layer remaining on the nails, which can be removed to ensure a smooth, dry finish.
The curing process is essential to the longevity and durability of gel nail polish. It allows the polish to harden and creates a strong, chip-resistant coating that can last for up to three weeks. This makes gel nail polish a popular choice for those seeking a long-lasting, high-shine manicure.

It is made of acrylic monomers and oligomers
The popularity of gel nail polish can be attributed to its lasting formula, which is a game-changer in the nail industry. Unlike traditional nail polish, which dries naturally, gel nail polish is cured under a UV or LED light, forming a hard, durable layer that can last for several weeks without chipping or peeling. This curing process involves the polymerization of acrylic monomers and oligomers, which are the primary constituents of gel nail varnish.
Acrylic monomers and oligomers are methacrylate compounds that serve as the building blocks of gel nail polish. When exposed to UV or LED light, these compounds undergo polymerization, forming long chains of polymers that interlink to create a robust and chip-resistant coating. The monomers, such as hydroxyethyl methacrylate (HEMA) and di-HEMA trimethyl-hexyl dicarbamate, play a pivotal role in the formation of the polymer network.
The photoinitiator is another crucial component in gel nail varnish. It absorbs ultraviolet light and splits into radicals, triggering the polymerization process. Common photoinitiators include benzoyl peroxide and diphenyl(2,4,6-trimethylbenzoyl)phosphine oxide. Additionally, plasticizers are incorporated into the formulation to impart flexibility and strength to the coating.
The formulation of gel nail varnish may also include oligomers or polymers with reactive methacrylate groups, which contribute to the overall performance of the product. These compounds form an interconnected polymer network, enhancing the chip resistance and longevity of the gel nail polish. Furthermore, gel nail polishes contain stabilizers, rheology modifiers, preservatives, solvents, and pigments to ensure product stability and provide a diverse range of colours.
It is important to note that while gel nail polish offers convenience and durability, proper care and maintenance are essential. Allowing nails to rest between applications and providing adequate time for nail beds to restore is recommended. Additionally, some gel nail polishes may contain potentially harmful substances, such as Butylated Hydroxyanisole (BHA), which has been linked to cancer-causing agents. Therefore, it is always advisable to review the ingredient list and make informed choices when selecting gel nail polishes.

It lasts longer than regular nail varnish
The main reason gel nail varnish lasts longer than regular nail varnish is due to its method of application and composition. Regular nail polish is a thinner, lacquer-like substance that dries naturally, leaving room for smudging and chipping. It can last a few days before it chips, and you can add a base coat or top coat to extend its wear time.
Gel nail polish, on the other hand, is made of a thicker, gel-like substance that is cured under UV or LED light. This process, called curing, involves placing the gel polish under a special lamp, causing it to harden and form a durable layer on the nails. This layer is resistant to chipping and peeling and can last for several weeks. The curing process also allows for a quicker drying time, reducing the chances of smudging or denting your manicure.
The durability of gel nail polish is further enhanced by its composition. It is made up of acrylic monomers and oligomers that bond together when exposed to UV light. This creates a hard, chemical-resistant coating that gives gel polish its long-lasting finish. Additionally, gel polishes contain pigments, either inorganic or organic, that provide vivid and long-lasting colour.
The longer-lasting nature of gel nail varnish also offers convenience and cost-effectiveness. With a gel manicure, you can save time and money by avoiding frequent touch-ups or reapplications, as the varnish can last for up to three weeks without chipping.
However, it is important to note that the longevity of gel nail varnish also depends on proper application. While gel polish generally offers superior shine and long-lasting wear, a poor application can lead to early chipping. Therefore, it is crucial to ensure correct usage and application techniques to achieve the desired results.

It is harder to remove than regular nail varnish
The removal of gel nail varnish is more difficult than that of regular nail varnish. This is because gel nail varnish is more robust and resistant to scratches, and it does not come off with a simple wipe. Instead, it has to be soaked off, or in some cases, filed off. The soaking method involves using an acetone soak, which can dry out your nails. The filing method is required for hard gels, which are rigid and impermeable to solvents.
The longer wear time of gel nail varnish, which can last up to three weeks, is one of its biggest advantages. It is thin and flexible, giving a natural look, and it stays on twice as long as regular nail varnish. This is because gel varnish is cured under a UV or LED lamp, which hardens the varnish and creates a hard, durable layer on the nails. The curing process involves polymerization, which is triggered by light and creates an interconnected polymer network that gives gels their chip resistance and staying power.
The removal of regular nail varnish is easier and faster, allowing for more frequent changes in colour. Regular nail varnish dries naturally through solvent evaporation, and it can be quickly fixed or removed with a simple wipe of acetone.
It is important to note that both types of nail varnish can cause damage to the nails due to the prep and removal processes. Therefore, it is recommended to take breaks between applications of any nail product to keep your nails healthy.

It is more expensive than regular nail varnish
The price difference between gel and regular nail varnish is due to several factors, including the curing process, durability, and application frequency. Firstly, gel nail varnish requires curing under a UV or LED lamp, which incurs additional costs for the lamp or access to a nail salon offering this service. This specialized curing process contributes to the higher price of gel nail varnish compared to regular nail varnish, which dries naturally.
Secondly, gel nail varnish is known for its durability and long-lasting wear, often advertised as lasting up to 3 weeks without chipping or losing its shine. This extended wear time reduces the frequency of manicures, saving time and money in the long run. While a quality regular nail varnish with a base and top coat can last up to 7 days, it is more prone to chipping and may require more frequent touch-ups or reapplication.
Additionally, gel nail varnish has a thicker, gel-like consistency that creates a hard, durable layer on the nails. This enhanced formula, often with high pigmentation and glossier finishes, contributes to the higher price point compared to regular nail varnish, which tends to have a thinner, lacquer-like consistency. The advanced formulation of gel nail varnish also strengthens and protects the natural nails, reinforcing them and reducing potential damage.
It is worth noting that gel nail varnish may be more challenging to remove, requiring soaking or filing, whereas regular nail varnish can be easily wiped away. This removal process for gel nail varnish can be more time-consuming and may involve additional costs for professional removal services or specialized products.
Overall, the higher price of gel nail varnish compared to regular nail varnish is justified by its durability, long-lasting wear, resistance to chipping, and the need for specialized curing equipment. These factors contribute to a more premium manicure experience, resulting in a higher price point for gel nail varnish.
