Gel nail polish is cured using a special type of light, specifically a UV or LED lamp. The process of curing gel nail polish is known as polymerisation, which causes the molecules in the gel polish to bond together, forming a solid layer of colour that won't chip or wear off easily. The two types of nail lamps differ in terms of the type of bulbs inside the unit and the kind of light they emit. LED lamps are generally faster, more expensive, and safer than UV lamps, but not all gel polishes are compatible with LED lamps.

What You'll Learn
LED vs UV nail lamps
LED and UV nail lamps are used to cure gel nail polish. The type of bulb inside the unit and the kind of light they emit are the key distinctions between the two. The decision on which nail lamp to purchase depends on your personal preference, budget, and the products you use.
LED Nail Lamps
LED nail lamps emit light in a specific wavelength, activating photoinitiators in the gel polish and causing it to harden. LED nail lamps can cure gel polish faster than UV light, typically taking less than a minute to cure a layer of gel polish. They also have a longer lifespan, with a bulb life of up to 50,000 hours, so you won't need to worry about changing the bulbs. However, not all gel polishes can be cured by an LED lamp, as they use a narrower wavelength than UV lamps. LED lamps also tend to be more expensive than UV lamps.
UV Nail Lamps
UV nail lamps emit broad UV wavelengths, which means they work on all types of gel polish. They typically take about two minutes to cure gel polish thoroughly. Most UV lamps have a bulb life of 1000 hours, and it is recommended to change the bulbs every six months. UV lamps are generally more affordable than LED lamps.
Hybrid Nail Lamps
There are also hybrid nail lamps on the market that offer both LED and UV functions, allowing users to switch between different types of gel polish.

The curing process
LED lamps emit UV light and can cure gel polish faster than UV lamps, typically taking 30 seconds to one minute to cure a layer of gel polish. They also have a longer bulb life, lasting up to 50,000 hours, and are safer than UV lamps as they deliver a smaller dose of UV. However, not all gel polishes can be cured by LED lamps, and some are designed specifically for UV nail lamps. It is important to check the compatibility of the gel polish with the LED lamp before use.
UV lamps, on the other hand, take longer to cure gel polish, typically around two minutes for a 36W UV lamp. They also have a shorter bulb life of 1000 hours and need to be replaced every six months. UV lamps are generally less expensive than LED lamps, but the curing process is slower.
Additionally, it is worth noting that regular nail polish will not cure under LED or UV lamps. However, if you have regular nail polish on, you can apply a top coat of Shellac or Gel and cure it under the lamp to extend the life of your manicure.

How to choose a lamp
There are a few key things to consider when choosing a lamp for curing gel nails. The two types of nail lamps used are LED or UV. The main difference between the two is the type of radiation emitted by the bulb. LED lamps emit a specific wavelength of light that activates the photoinitiators in the gel polish, causing it to cure or harden. This process can be much faster than with UV lamps, taking as little as 30 seconds. LED lamps also tend to last longer, while UV lamps often need bulbs replaced.
However, not all gel polishes can be cured by an LED lamp, and some are designed specifically for UV lamps. Therefore, it is important to check the compatibility of the gel polish brand with the type of lamp. The wattage of the lamp is also a factor to consider, as higher-watt bulbs can cure gel polish faster, which is advantageous in a salon setting.
Another consideration is the cost, as LED lamps typically cost more than UV lamps. Additionally, the design of the lamp is important, especially if it needs to accommodate a hand or foot. Some lamps also have additional features such as a timer or a reflector to help bounce the light around.
When choosing a lamp, it is recommended to follow the gel manufacturer's guidelines to ensure the proper curing of their specific gel product. This includes specifying the wattage, curing time, and other features of the lamp. It is also important to note that cheaper curing lights may not produce the proper wavelength or intensity to cure gel nails effectively, which can increase the potential for allergies to develop.

The history of gel curing lamps
In the early 2000s, gel curing lamps that used UV lights were introduced. These lamps delivered a strong source of UV light over a longer period. The first generation of UV-cured gel systems, introduced in the 1990s, was hard and inflexible, and often used as a coating over traditional acrylic nails. At the turn of the 21st century, lighter and more flexible UV gel systems were introduced, improving their potential to replace conventional acrylic systems.
The development of Shellac, a "power polish", further boosted the popularity of gel nail systems. Shellac combined the longevity and gloss of gels with the easy application of traditional nail polish. This led to the launch of numerous products, including Gelish, the first gel polish packaged in a traditional nail polish bottle.
Simultaneously, advancements in LED technology enabled the creation of safer, faster, and more efficient curing systems for gel nail polish. LED curing lamps provide the specific wavelength of light needed to activate the photoinitiators in gel polish, causing it to cure or harden. The reduction in curing times, from around 10 minutes with UV lamps to just 30 seconds with LED lamps, was a significant advantage for salons.
Today, the market for gel nail polish continues to expand, driven by consumer demand for salon-quality results at home. Companies now offer at-home gel nail kits with LED lamps, allowing users to achieve professional results from the comfort of their homes. Concerns about the potential harm caused by UV exposure have also prompted innovations in LED and low-heat curing technology.

Pros and cons of LED and UV lamps
LED and UV lamps are both used to cure gel nail polish. The type of lamp you use depends on your personal preference, budget, and the products you use. Here are some pros and cons of each type of lamp to help you decide which one is better suited for your needs.
LED Lamps
LED lamps, or "light-emitting diodes", are a type of light bulb that emits a variety of colours, including red, blue, yellow, and purple. They are designed to cure gel nail polish and provide a specific wavelength of light that activates the photoinitiators in the gel polish, causing it to cure or harden. LED lamps have a higher wattage than regular LED lights, making them much brighter and more intense. They also have a longer bulb life than UV lamps, lasting up to 50,000 hours, so you won't need to worry about changing the bulbs. LED lamps are also faster at curing gel polish, typically taking 30-45 seconds per layer, compared to 2 minutes for a UV lamp.
However, not all gel polishes can be cured by an LED lamp. Some gel polishes are designed specifically for UV lamps, so it's important to check the compatibility of the gel polish brand you are using with an LED lamp.
UV Lamps
UV lamps use UV bulbs that emit ultraviolet light, specifically Ultraviolet-A (UVA), which is considered safer for humans than Ultraviolet-B (UVB). These bulbs need to be replaced frequently, typically every six months, and have longer curing times. However, UV lamps are compatible with a wider range of gel polishes, including those designed specifically for UV lamps.
In terms of safety, both UV and LED lamps emit minimal amounts of UV rays, and the risk of sunburn or skin damage from their use is extremely low. According to Dr Stern, a New York City-based dermatologist and nail specialist, "even if you were to have a gel manicure every week, your chances of developing skin cancer would not be increased."

Frequently asked questions
Gel nail polish is cured using either a UV or LED lamp.
LED lamps cure gel polish faster than UV lamps. LED lamps are also brighter and more intense than regular LED lights.
Curing gel polish involves using a specially designed UV or LED light to seal and harden the gel nail polish. This process is known as polymerisation, causing the molecules in the gel polish to bond together, forming a solid layer that won't chip or wear off easily.
Curing time depends on the brand of gel polish being used and the type of lamp. Typically, an LED lamp cures a layer of gel polish in 30 seconds to 1 minute, while a UV lamp takes around 2 minutes.
When choosing a lamp, consider factors such as size, wattage, brand compatibility, and customer reviews. It is also important to follow the recommendations of the gel manufacturer to ensure proper curing.
