Gel nail polishes are popular for their quick-drying time and long-lasting wear. Typically, gel polishes are cured using a UV light or LED lamp, which emits specific UV wavelengths and intensities to harden the polish. While there are black light UV fixtures available, it is unclear whether these are powerful enough to cure gel nails. It is important to note that UV light emits ultraviolet radiation, which can be dangerous to one's health, so it is recommended to use non-UV gel nail polishes or alternative drying methods such as quick-drying nail polish sprays or ice water.

What You'll Learn
LED or UV light?
Gel nail polishes are cured using UV light or LED lamps. While the sun emits UV light, it does so at various wavelengths and intensities, and cannot be used to cure gel nails. Only UV light or LED lamps can cure gel nails, and they are specifically calibrated to do so.
LED lamps are powerful yet compact, and deliver optimal light exposure to ensure your gel nails cure perfectly, resulting in a long-lasting, chip-free finish.
UV light, on the other hand, emits ultraviolet radiation, which can be dangerous to your health. If you are curing your gel nails with UV light, it is recommended to use a UV LED lamp, which combines the curing capabilities of UV light with the precision and safety of LED technology.
If you do not have access to a UV light or LED lamp, you can purchase a non-UV gel polish, which dries without the use of a lamp. Examples of non-UV gel polishes include Sally Hansen's Miracle Gel line and Essie's Gel Couture line. These polishes are applied like regular nail polish and dry on their own. To speed up the drying process, apply thin, even coats. You can also try a gel alternative, such as Dazzle Dry's four-step manicure kit, which air-dries in five minutes without a UV lamp.

Is a black light harmful?
It is important to differentiate between black lights and UV lights. Black lights emit a type of ultraviolet radiation called UVA, which is invisible to the human eye. They are often used in industry, nightclubs, or amusement parks to make things glow. On the other hand, UV lights emit specific UV wavelengths and intensities and are used to cure gel nail polish. While quick-drying polish sprays are generally formulated for non-gel nail polishes, they may also help dry non-UV gel polishes faster. However, only UV light can cure gel polishes.
Black lights are usually fluorescent lamps or incandescent light bulbs modified to allow only the emission of UVA and some visible light. The amount of ultraviolet radiation they emit is very low, and exposure to UVA from black lights is well below the recognized safe limits. They are not hazardous to people using them or working near them. However, UVA is thought to cause premature aging and has been linked to some skin cancers, although UVB is the primary cause.
While it is not hazardous, you wouldn't want to stare at a black light for too long. The danger with light outside of the visible spectrum is that you can't see the potential harm. Similarly, while black lights are generally safe, you should avoid pointing them directly at your eyes.
In conclusion, black lights are not inherently harmful and are safe for use in the home. However, it is important to use them responsibly and avoid prolonged direct exposure, particularly to the eyes, as with any type of lighting or radiation.

What is a UV light?
UV light, or ultraviolet light, is a type of electromagnetic radiation with wavelengths between 10 and 400 nanometers. This places it at a frequency higher than that of visible light, but lower than X-rays. UV light is present in sunlight and accounts for about 10% of the total electromagnetic radiation output from the Sun.
UV light can be further categorised into different types based on wavelength: UVA, UVB, and UVC. UVA rays have the longest wavelengths among the three and can penetrate the skin more deeply, causing premature ageing and playing a role in skin cancer formation. UVB rays, while less common than UVA rays, are very high energy and can damage skin cells and DNA, leading to melanoma and other types of skin cancer. UVC rays have the shortest wavelengths and are the most harmful, but they are absorbed by the atmosphere and do not reach the Earth's surface.
UV light has various practical applications, including its use in gel nail curing. The UV light emitted by nail lamps is specifically calibrated to cure gel nail polish. While sunlight also emits UV light, it does so at various wavelengths and intensities, making it unsuitable for curing gel nails.
UV light has both beneficial and detrimental effects on human health. For example, while exposure to UV light can lead to sunburn, skin ageing, and an increased risk of skin cancer, it is also essential for the production of vitamin D in humans. Additionally, the sterilising properties of UV light can be utilised to kill bacteria and sterilise surfaces.

How long does it take to cure gel nails?
The curing time for gel nails depends on the type of gel polish, the number of coats, and the curing method. Here is a step-by-step guide on curing gel nails and the time required for each step:
Preparation (5-10 minutes):
This includes removing old nail polish, filing, shaping, and buffing your nails to create a smooth base for the gel polish application.
Base Coat Application (2-3 minutes):
Apply the base coat evenly to all nails. This step ensures that the gel polish adheres properly and creates a durable base.
Curing the Base Coat (1-2 minutes):
Place your nails under a UV lamp or LED light for 1-2 minutes to cure the base coat. This step will vary depending on the type of light used and the specific gel polish instructions.
Gel Color Application (15-20 minutes):
Apply two to three coats of gel colour, allowing each layer to dry before applying the next. Each layer may require 1-2 minutes of curing under the lamp. This process can take longer if you are creating intricate nail designs.
Curing the Top Coat (30 seconds to 5 minutes):
The curing time for the top coat depends on the type of gel polish and the light source. If you are using a UV LED light, it should take around 30 seconds to one minute. However, if you are using a traditional UV light, it may take up to 5 minutes or longer.
It's important to note that the curing time can vary depending on the brand of gel polish, the thickness of the application, and the power of the light source. Always refer to the manufacturer's instructions for specific curing times and follow safety guidelines to avoid heat spikes and ensure proper curing.
Additionally, it's worth mentioning that there are alternative methods to cure gel nails without using a UV light or LED lamp. These methods include using non-UV gel polishes, quick-drying nail polish sprays, and sun-cured gel nail stickers, which can reduce the overall curing and application time significantly.

What are the alternatives to UV light?
There are several alternatives to UV light for curing gel nails. Firstly, it is important to note that only an LED lamp can cure gel polish as effectively and quickly as a UV light. However, there are other methods that can be tried at home. One option is to use non-UV gel nail polishes, which are formulated to air-dry without the need for a UV or LED lamp. These include Sally Hansen's Miracle Gel line and Essie's Gel Couture line, which are applied like regular nail polish and dry on their own. Dazzle Dry is another product that offers a four-step manicure kit that air-dries in five minutes without a UV lamp.
Additionally, quick-drying nail polish sprays can be used to speed up the drying process of non-UV gel polishes. After painting, spray on a light coat of the quick-drying polish spray and allow it to dry for the recommended time, usually around 5 to 10 minutes. Another method is to submerge your nails in ice water for about 3 minutes after applying the non-UV gel polish. While it won't cure the gel polish, spraying just-painted nails with canola oil cooking spray can help the polish dry faster by thinning it out.
Some salons, like Lontis Day Spa & Salon in Minneapolis, opt for LED light dryers instead of UV lights due to the potential health risks associated with UV radiation. LED lights are also used with CND polish as an alternative to UV curing.
