Gel nail polish is a type of nail coating that is cured and hardened under a UV or LED light source. It is known for its long-lasting, chip-resistant properties, with manicures lasting up to 3 weeks. The application process involves curing each coat of colour under a special light, which creates a hard, durable layer on the nails. This process also ensures that the manicure dries quickly and is resistant to smudging. The popularity of gel nail polish can be attributed to its wide range of colours and finishes, as well as its ability to strengthen and protect natural nails. However, there are some safety concerns surrounding the use of UV lamps and certain ingredients in the polish, such as methacrylates and butylated hydroxyanisole (BHA). Despite this, gel nail polish remains a popular choice for those seeking a durable and aesthetically pleasing manicure.

What You'll Learn
Composition and application
Gel nail polish is a thicker, gel-like substance that is cured under UV or LED light to create a hard, durable layer on the nails. It is composed of a base coat, two coats of colour, and a top coat. The base coat is applied directly to the nail, followed by two thin coats of colour, and finally, a top coat. Each layer is cured under a UV or LED lamp for 30 seconds to two minutes to harden the polish and ensure that it does not chip. The full process, from application to curing, can take up to 15 minutes.
The composition of gel nail polish is different from regular nail polish. Regular nail polish is made up of nitrocellulose and pigments dissolved in a volatile organic solvent, whereas gel nail polish contains methacrylates (the building blocks of polymers), photoinitiators, pigments, stabilizers, rheology modifiers, preservatives, and solvents. The photoinitiators in gel nail polishes are molecules that initiate a chemical reaction upon absorption of light at a specific wavelength, typically ultraviolet (UV) light. This reaction causes the building blocks in the solution to connect and form long polymer chains that harden on the nail.
To apply gel nail polish, the nails must first be thoroughly cleaned to remove any oils or residue. The cuticles are then pushed back, and the nails are shaped using a nail file. Next, the base coat is applied, followed by two thin coats of colour, and a top coat. Each layer is cured under a UV or LED lamp. It is important to note that the coats of colour should be applied thinly, as a thick coat can cause wrinkling. After curing, the tacky layer should be wiped from the nails using a lint-free wipe soaked in a cleanser.
The removal process for gel nail polish is more difficult and time-consuming than that of regular nail polish. Gel nail polish must be soaked or filed off, and it is recommended to follow a specific process to avoid damaging the nails. Firstly, the nail surface is gently buffed to break the seal of the polish. Then, a cotton ball soaked with nail polish remover is placed on the nail and allowed to soak for 15 to 20 minutes. Finally, the cotton and foil are gently twisted and lifted from the nail, and any remaining gel residue is pushed off using a cuticle stick.

Curing methods
Unlike regular nail polish, gel nail polish cannot dry naturally and requires curing under a UV or LED lamp. Curing gel polish involves placing your nails under a lamp to activate a chemical process that dries the polish and seals and hardens it into a durable layer. This process is known as polymerisation, where the molecules in the gel polish bond together to form a solid layer of colour that is resistant to chipping, smudging, and wearing off.
To cure gel nail polish, start by setting a timer and activating the lamp. Remain still and keep your hands under the lamp for the duration of the curing process, which can vary from a few seconds to several minutes depending on the product and lamp used. It is crucial to cure each layer completely before applying the next one, and to avoid running the UV lamp for more than 10 minutes when working on both hands.
When using a UV lamp, ensure that you follow the recommended guidelines, cure times, and lamp specifications provided by the manufacturer. Additionally, for frequent use, replace the UV bulb every 2-4 months to maintain its effectiveness.
LED lamps offer faster curing times and produce less heat, making them a suitable option for individuals with sensitive skin or nails. On the other hand, UV lamps are preferred by some technicians for their higher power output and wider working area. Ultimately, the choice between UV and LED lamps depends on personal preference and specific needs.
To test if your gel polish is curing properly, apply a bead of gel to a form and cure it for the recommended time. If the underside of the gel is still liquid after curing, it indicates that the product has not cured properly.

Durability and resistance to chipping
Gel nail polish is known for its durability and resistance to chipping. It is made up of acrylic monomers and oligomers that bond together when placed under UV light, creating a hard, durable layer on the nails. This process, called curing, transforms the once-liquid gel into a hard, chemical-resistant coating. Unlike traditional nail polish, gel polish can last for several weeks without chipping or peeling, making it a popular choice for those seeking a long-lasting manicure.
The durability of gel nail polish can be attributed to its thicker, gel-like consistency and the curing process under UV or LED light. This curing process ensures that the gel polish dries quickly and forms a hard, protective layer over the nails. As a result, gel manicures are less prone to chipping and can withstand everyday activities that would typically cause regular nail polish to chip.
However, it is important to note that gel nail polish is not completely immune to chipping. Several factors can contribute to chipping, including improper application, poor-quality products, and exposure to water or certain activities. For example, if the gel polish is applied too close to the cuticles or if the nails are not prepared properly before application, it may lead to lifting and chipping. Additionally, occupations or hobbies that require constant handwashing or working with soil can increase the chances of chipping, as the water and dirt can wear off the top coat over time.
To maximize the durability of gel nail polish and prevent chipping, it is crucial to ensure proper nail preparation and correct product application. This includes buffing the nails to create a slightly rough surface for better adhesion and degreasing the nail plate with a nail cleaner or acetone to remove oils. Applying a thin base coat is also recommended, as it adheres better to the nail and provides a strong foundation for the coloured gel layers.
Overall, gel nail polish offers superior durability and resistance to chipping compared to traditional nail polish. With proper care and application, a gel manicure can last for several weeks, providing a flawless, long-lasting finish.

Removal process
Gel nail polish is a thin brush-on formula, designed for high performance and a glossier finish than regular nail polish. It is cured under UV or LED light to create a hard, durable layer on the nails. While it is possible to remove gel nail polish at home, it is recommended to go to a professional nail technician to have it removed to avoid damaging your nails.
The first method for removing gel nail polish is to let your nails grow out. Clipping them once a week will remove the gel nail polish and help prevent the nails from catching on clothing and other objects. This method is very slow, taking about six months for fingernails and 12 to 18 months for toenails.
The second method is to soak your nails in acetone. First, use a nail file to break the seal on each nail's free edge and sidewalls. Then, fully saturate a cotton ball with acetone, and place it directly on top of the nail. Allow the cotton to sit on the nail for at least 15-20 minutes. You can then gently press and twist the foil and cotton off of each nail. Take a cuticle stick and gently push any remaining gel residue off. Finally, lightly cleanse the nail surface with a cotton ball (or pad) and rubbing alcohol.
It is important to note that gel nail polish can only be removed with acetone if it is the soak-off gel variety. If it is hard gel, it will need to be filed off.

Safety concerns
Gel nail polishes are cured and set using UV or LED light, which hardens the polish and dries it almost instantly. This process, however, has raised several safety concerns.
UV Radiation Exposure
The most significant concern is the exposure to ultraviolet radiation during the curing process. Ultraviolet A (UVA) rays are known to cause cellular damage, skin ageing, and an increased risk of skin cancer. This is true for both traditional UV lamps and newer LED curing lamps, which are intended to make the process faster and safer. A study published in Nature Communications found that an LED nail dryer caused DNA damage to mouse and human cells in vitro. While the amount of time under the lamp required to cause serious damage is debated, the American Academy of Dermatology recommends that people who regularly get gel manicures protect their skin with sunscreen or fingerless gloves.
Chemical Irritants
The chemicals used in gel nail polishes, such as acrylate and methacrylate, are also a cause for concern. These substances are known to cause allergic reactions, including contact dermatitis and, less commonly, urticaria. Methacrylates are skin irritants and sensitizers, and people can develop serious allergies over time. This is particularly problematic because acrylates are used in various medical products, such as bone cement, dental fillings, and diabetic insulin pumps.
Nail Damage
The removal process of gel nail polish can be destructive to nails, often involving aggressive buffing, scraping, and peeling, which can injure the nail plate and cuticle. This can result in severe brittleness, dryness, and temporary nail thinning. It is recommended to allow time between manicures for nails to recover and to moisturize with lotion or cuticle oil.
Sanitation
When applied in salons, gel nail polishes can pose sanitation risks. Communal jars of powder may be used for multiple people, creating a potential reservoir for bacteria, fungi, and viruses.
Overall, while gel nail polishes offer long-lasting and chip-resistant manicures, it is important to be aware of these safety concerns and take appropriate precautions to minimize potential risks.
