Gel nail polish is cured and hardened under a lamp that emits ultraviolet (UV) light. There are two types of nail-curing lamps: LED and UV. LED lamps cure gel polish faster than UV lamps, making them ideal for busy salons. However, not all gel polishes can be cured by an LED lamp as they use a narrower wavelength than UV lamps. On the other hand, UV lamps emit a broader light spectrum, making them compatible with a wider range of gel polishes. While UV exposure has been linked to skin damage, the amount of UV rays emitted by nail curing lamps is considered safe for humans.

What You'll Learn
LED vs UV nail lamps
LED and UV nail lamps are the two types of nail lamps used to cure gel nail polish. The type of bulb inside the unit and the light they emit are the key distinctions between the two. The type of radiation emitted by the bulb determines the difference between an LED and a UV nail lamp.
LED nail lamps cure gel nail polish faster than UV lamps, making them ideal for busy salons that want to serve more clients in a day. Typically, an LED lamp will cure a layer of gel polish in 30 seconds, whereas a 36-watt UV lamp will take about two minutes to do the same job. LED nail lamps also have a longer lifespan than UV light models, making them better long-term investments. LED lamps should last for 50,000 hours, so you won't have to worry about changing the bulbs. On the other hand, most UV lamps have a bulb life of 1000 hours, and it is advised to replace the bulbs every six months.
UV lamps emit a wider spectrum of light than LEDs, making them compatible with a broader range of gel polishes. They also activate the photoinitiators in gel polish. However, not all LED nail lamps can cure every type of polish, and some polishes are designed specifically for UV nail lamps. Therefore, it is important to check whether the brand of gel polish you are using is compatible with an LED lamp.
Although prolonged exposure to UV rays has been linked to skin damage, research has shown that the amount of UV rays emitted by UV, UV/LED or LED lamps used for gel manicures is very minimal, making them safe for use. A 2013 study found that even for the worst lamp evaluated, 30 minutes of daily exposure to this lamp was below the occupational exposure limits for UV radiation. At this time, there is also no evidence that gel nail lamps cause cancer.

How to cure gel nails
There are two types of nail lamps used to cure gel nail polish: LED and UV. The difference between the two is the type of radiation emitted by the bulb. While LED lamps do not use any UV light, UV lamps emit minimal UV radiation, which is considered safe for use.
To cure gel nails using a UV or LED lamp, start by cleaning your nails thoroughly. Push back the cuticles and buff the nail surface to create a smooth base. Apply a thin layer of gel base coat and cure it under the lamp for 45 seconds with LED or 2 minutes with UV. The base coat will be slightly tacky after curing so that the next layer can adhere properly.
Next, apply a thin layer of gel colour polish. For vibrant colours, two coats may be necessary. Cure each colour layer under the lamp. Finally, apply a thin layer of the top coat. The top coat is a protective barrier that shields the colour and provides a long-lasting shine. Cure the top coat under the lamp.
If you do not have access to a UV or LED lamp, you can use a non-UV gel nail polish. These polishes are specially formulated to air-dry without being cured under a nail lamp. Apply thin, even coats to speed up the drying process. After painting, you can also spray on a quick-drying nail polish spray or submerge your nails in ice water for about three minutes.

Safety concerns of UV light
The two types of nail lamps used to cure gel nail polish are LED or UV lamps. These refer to the type of bulbs inside the unit and the kind of light they emit. While both emit UV radiation, they predominantly produce Ultraviolet-A (UVA) rays, which are considered safer for humans when compared to Ultraviolet-B (UVB) rays.
Despite this, there are still some safety concerns regarding the use of UV light for gel nails. Firstly, while the UV exposure from nail lamps is considered minimal, prolonged exposure to UV rays has been linked to skin damage and premature skin aging. To mitigate this risk, it is recommended to apply sunscreen or wear UV gloves before using a gel nail lamp. Additionally, it is important to check for any medications or conditions that may increase sensitivity to UV radiation, as this could impact the safety of using these lamps.
Another concern is the potential for UV light to cause cancer. While studies have shown that the risk of developing skin cancer from using gel nail lamps is low, there is a rare but potentially aggressive form of skin cancer called subungual (under the nail) squamous cell carcinoma. Applying sunscreen before using a gel nail lamp can help reduce this risk, but it may not provide complete protection against this form of cancer.
Furthermore, some people have reported developing allergies around their fingertips from gel nails. While this is not a direct result of UV light exposure, it is an important consideration when deciding whether to use gel nail polish.
Overall, while modern gel nail lamps have made the process much safer, it is still important to be aware of the potential risks associated with UV light exposure and take the necessary precautions to ensure safe use.

LED nail lamp advantages
The use of light to cure or dry nail polish is a common practice in nail care. While both LED and UV lamps emit light, there are several advantages to using an LED lamp over a UV lamp.
Firstly, LED lamps are considered safer for the skin and nails. Although the risk of skin damage from UV exposure during gel manicures is generally low, LED lamps emit significantly less UV radiation than UV lamps, reducing the potential for skin damage and lowering the risk of skin cancer. This makes them a preferable option for those concerned about the potential risks associated with UV radiation exposure.
Secondly, LED lamps offer faster curing times. LED lamps can cure gel polish in as little as 30 to 60 seconds, while UV lamps typically take between 2 to 3 minutes. This faster curing time saves time and allows users to get on with their daily activities without worrying about smudging their nails. The higher energy levels of the light emitted by LED lamps contribute to this quicker curing process.
Thirdly, LED lamps provide longer-lasting manicures. By curing polish under an LED lamp, a stronger bond is formed between the polish and the nails, making it more durable and resistant to chipping or peeling. This helps to extend the life of the manicure and maintain its appearance.
Additionally, LED lamps are more environmentally friendly and cost-effective. They consume less power than UV lamps and have a longer lifespan, with bulbs lasting up to 50,000 hours. This reduces the need for frequent bulb replacements, resulting in both economic and ecological benefits.
Lastly, LED lamps can help achieve a more professional-looking manicure. They ensure that the polish dries evenly, creating a smooth and glossy finish. This can be more challenging to attain when air-drying nails, and LED lamps provide a convenient solution for achieving a sleek and uniform manicure.
In summary, LED nail lamps offer several advantages, including enhanced safety, faster curing times, longer-lasting manicures, environmental and economic benefits, and improved manicure results. These benefits make LED lamps a popular choice for both professionals and individuals seeking efficient and effective nail care solutions.

Bulb wattage and curing speed
The wattage of a bulb is an important factor in curing gel nails. The higher the wattage, the faster the curing process. Most professional LED and UV nail curing lamps are at least 36 watts. LED lamps with higher wattages can cure gel nails within seconds, while UV lamps typically take longer. For example, a 36-watt UV lamp takes two minutes to cure a layer of gel polish, whereas an LED lamp of the same wattage can do the same job in 30 seconds.
LED nail curing lamps differ from regular LED lights as they have a much higher wattage. This is because gel polish requires a higher level of UV radiation than what a regular light bulb can provide. Not all LED nail curing lamps are compatible with all gel polishes, as some polishes are designed specifically for UV lamps. It is important to check whether the brand of gel polish being used is compatible with an LED lamp.
The wattage of an LED nail curing lamp can vary, with some lamps offering wattages of 10 watts, 12 watts, 24 watts, 48 watts, or 60 watts. The higher the wattage, the faster the curing process. For example, a 12-watt or 24-watt lamp may be adequate for infrequent users, while professionals or those who routinely perform gel manicures may prefer a 48-watt or 60-watt lamp for faster curing.
The distance between the LED emitters and the fingernails also plays a critical role in the curing process. Additionally, the type of LED emitters (bulbs) and their placement can vary, impacting the performance of the curing light. It is recommended to follow the gel manufacturer's instructions for the proper light unit required to cure their specific gel products.
While higher wattage bulbs can reduce curing time, it is important to consider other factors that may impact the overall curing speed. For instance, the time it takes to apply the next coat of colour while one hand is in the lamp can affect the total curing time. Therefore, the curing speed is influenced by both the wattage of the bulb and the application process.
