Gel nail polish is a popular product that offers a long-lasting, chip-resistant manicure. Unlike traditional nail polish, gel polish is cured and hardened under a UV or LED lamp, creating a glossy finish that lasts for weeks. The process of applying gel nail polish involves several steps, including prepping the nails, applying a base coat, the gel polish, and a top coat, and then curing the nails under the lamp. While gel polish provides durable and aesthetic results, it also raises safety concerns due to the potential UV damage to the skin. Proper care and removal techniques are essential to maintain the health of natural nails.

What You'll Learn
Gel polish application and removal
Gel polish is a type of nail polish that is cured and hardened using a UV or LED lamp. This process, known as polymerisation, seals the polish, creating a long-lasting, chip-resistant layer. Before curing, ensure your nails are clean and dry. Position your hands so that only your fingernails are exposed to the UV light, and keep them still to achieve a flawless finish. The curing time depends on the product used, but it typically takes one to two minutes. After each gel layer is applied, it needs to be cured completely before continuing.
To remove gel polish, you can use acetone. However, if the gel polish has been over-cured, it will be difficult to remove with acetone, and you will need to gently file it off to prevent damage to your natural nails.
Some gel polishes do not require curing with a lamp and can air-dry naturally. These "gel-like" polishes are similar to regular nail polish but are usually thicker. To speed up the drying process, you can use a fast-drying top coat, dip your fingers in ice water, or use nail-drying sprays.

Gel polish ingredients and chemistry
The unique properties of gel nail polish are due to its distinct chemistry compared to regular nail polish. The key ingredients and chemical processes involved in gel nail polish are what set it apart.
The stars of the show are the monomers and the photoinitiator. The photoinitiator absorbs ultraviolet light and splits into radicals, which then kick-start polymerization by cuing the monomers to link up into polymer chains. This process results in the formation of a durable, chip-resistant coating on the nails. Two common photoinitiators used in gel nail polishes are benzoyl peroxide and diphenyl(2,4,6-trimethylbenzoyl)phosphine oxide.
The monomers that the photoinitiator pushes to polymerize are a mixture of various methacrylates. Hydroxyethyl methacrylate (HEMA) is a significant component of many gel polishes. Di-HEMA trimethyl-hexyl dicarbamate, another common ingredient, has two methacrylate groups and can function as a cross-linker between polymer chains, further enhancing the strength of the coating.
The removal process for gel nail polish also differs from that of regular nail polish. Gel nail polish requires prolonged soaking and dissolution in acetone, as it has lower solubility in acetone than regular nail polish. Weaker solvents, such as ethyl acetate, have minimal effect on gel polish. It is recommended to use a cotton ball soaked in acetone rather than soaking the fingers directly to avoid skin irritation.

Gel polish vs. regular polish
When it comes to nail polish, there are two main types to choose from: gel polish and regular polish. So, how do they compare?
The main difference between gel polish and regular polish is their longevity. Gel polish is designed to last longer, typically up to 21 days, whereas regular nail polish dries and can be left to dry naturally, but it is more prone to chipping and damage and doesn't tend to stay on the nails for very long. Gel polish is hardened under a LED or UV lamp, which means there is no drying time, and it results in a stronger manicure. However, this also means that the removal process is more labour-intensive and time-consuming, requiring acetone and either foils or the double boiler method.
Another difference is the application process. Regular nail polish is easy to apply and can be done at home, whereas gel polish usually requires a trip to the salon and takes longer to apply. The process for applying gel polish includes filing/shaping, a base coat, colour, and a top coat, and it must be cured under a lamp. Regular nail polish can also include a base and top coat, but it is not essential, and it dries in the air.
The choice between gel and regular polish depends on personal preference and lifestyle. If you want a long-lasting manicure and don't mind the extra time and cost involved, gel polish is a good option. However, if you like to change your nail colour frequently, regular polish might be a better choice, as it is easier and faster to remove.

Gel polish kits and costs
Gel manicures can be expensive, with salon prices ranging from $38 to $110. However, there are many at-home gel nail kits available that can save you money in the long run. These kits typically include everything you need for a DIY manicure, such as nail files, buffers, gel lacquers, top coats, and LED drying lamps.
One popular option is the Olive & June The Gel Mani System, which comes with 14 components, including a nail file, buffer, LED curing lamp, and their patented Poppy device, which helps you paint your nails with your non-dominant hand. This kit provides a salon-quality finish that lasts for up to two weeks without chipping. Another highly-rated option is the Morovan Poly Gel Kit, which offers impressive results in terms of drying time, appearance, longevity, ease of removal, and nail integrity post-removal. While there is a slight learning curve with this kit, the directions are clear and concise.
For those on a budget, there are even more affordable options available, such as the Gellen Cat Eye Gel Nail Polish Kit, which can be purchased from Walmart for $13.49, and the modelones Gel Nail Polish Kit, which is also available from Walmart for $11.99. These kits may not last as long as salon manicures, but they are still a great option for those who want to try gel nails at home without breaking the bank.
In addition to the initial kit cost, it is important to consider the cost of gel removal. Some kits, like Le Mini Macaron, come with gel-removal packets, while others may require purchasing a separate removal system. Removing gel polish at home can save you money, but it is important to be careful, as improper removal can damage your nails.

Frequently asked questions
Gel nail polish is a type of nail polish that is cured with a UV or LED lamp to create a shiny, long-lasting manicure that doesn't require extensive time to dry. It is tougher and more durable than traditional nail polishes, so you don't have to worry about chips or smudges.
First, you need to prep your nails by cleaning them with acetone to remove any oils or residue. Then, you can start applying the gel polish. Apply a thin layer of the base coat to the nails, making sure it's even. Cure the base coat under a UV or LED lamp for 30 seconds to 2 minutes. Then, apply the gel nail polish colour and cure it under the lamp again. Finish with a gel top coat to seal in the colour and provide a glossy finish.
To remove gel nail polish, you can use acetone. Soak a cotton ball in acetone and place it on your nail, then wrap your finger in aluminium foil to keep it in place. After 10-15 minutes, you should be able to gently scrape or pull the gel polish off. Alternatively, you can soak your nails in pure acetone or use a product like CND Shellac.
