There are two types of nail lamps used to cure gel nail polish: LED and UV. Both emit ultraviolet radiation, predominantly in the form of UVA, which is associated with a higher risk of skin cancer. However, a 2014 study found that the level of UVA exposure from a gel manicure every two weeks is probably not high enough to significantly increase the risk of skin cancer. LED lamps are generally considered safer than UV lamps as they deliver a smaller dose of UV light more swiftly, but it's important to follow the manufacturer's instructions to avoid under-curing the gel, which can lead to allergies and infections.

What You'll Learn
LED vs UV nail lamps
The two types of nail lamps used to cure gel nail polish are classified as either LED or UV. This classification is based on the type of bulbs inside the unit and the kind of light they emit.
Both LED and UV nail lamps emit ultraviolet radiation, predominantly in the form of UVA. However, UV lamps emit a broader light spectrum than LEDs, making them compatible with a wider range of gel polishes. They also take longer to cure the polish, typically around two minutes, whereas LED lamps cure a layer of gel polish in around 30 seconds. This makes LED lamps ideal for busy salons.
LED lamps tend to be more expensive than UV lamps, but they also last longer, with a bulb life of 50,000 hours, compared to 1000 hours for UV lamps. This means you are unlikely to have to replace the bulbs in an LED lamp.
While it has been proven that UV exposure from nail lamps will cause minimal to no damage to a client's skin, if you are concerned about this, it is best to stick to LED lamps, as they emit little to no UV light. Not all gel polishes are compatible with LED lamps, so it is important to check the packaging before purchasing.

Safety concerns about UV radiation
The use of UV light to cure gel nails has raised some concerns due to its emission of ultraviolet A (UVA) radiation, which has been associated with an increased risk of skin cancer. While the American Academy of Dermatology states that both UV and LED lamps emit this form of radiation, it is important to note that the risk associated with gel manicures is considered relatively low. A 2014 study in JAMA Dermatology concluded that the level of UVA exposure from a gel manicure every two weeks is likely insufficient to significantly elevate the risk of skin cancer.
However, it is still advisable to be cautious. To minimise potential risks, it is recommended to use sunscreen or wear fingerless gloves during the manicure process. LED lamps, which deliver a lower dose of UV light more swiftly, are also considered a safer alternative. They cure gel polish faster than UV lamps and typically take 30 seconds to cure each layer of gel polish, compared to the 2 minutes required by a UV lamp.
While LED lamps are generally safer, it is worth noting that not all gel polishes are compatible with them, and some are specifically designed for use with UV lamps only. Therefore, it is essential to check the compatibility of the gel polish brand with LED lamps before use. Additionally, LED lamps tend to be more expensive than UV lamps, but they last longer and do not require frequent bulb replacements.
In summary, while the use of UV light for curing gel nails has been associated with potential health risks due to UVA radiation exposure, the actual risk of developing skin cancer from occasional manicures is relatively low. Nevertheless, taking precautionary measures, such as using sunscreen or fingerless gloves, and opting for LED lamps can further reduce these risks and provide a safer manicure experience.

How to use an LED nail lamp
While nail salon lamps, whether labelled as LED or UV, emit ultraviolet radiation, the newer LED lamps deliver a much smaller dose of UV and do it more swiftly. This means that a nail curing light that uses LED bulbs is safer than one that uses UV bulbs.
- Prepare your nails: Ensure your nails are strong enough for a gel manicure. If your nails are too weak, they can bend and cause the gel nail polish to pull away from the nail. Nourish your nails with products such as cuticle oil, moisturiser, and nail defence to improve their strength. You can also add a builder gel to your manicure routine.
- Lay out your materials: Gather your UV light, base coat, colour, top coat, orange stick, cotton balls, and 99% isopropyl alcohol.
- Clean your hands and nails: Wash your hands and nails thoroughly before beginning the manicure process.
- Apply the base coat: Start by applying a thin layer of base coat to your nails.
- Cure the base coat under the LED lamp: Place your hand under the LED lamp and set a timer for 45 seconds to cure the base coat.
- Apply the colour coat: After the base coat has been cured, apply two coats of colour, curing for 45 seconds after each coat.
- Wipe your nails with isopropyl alcohol: Use a cotton ball soaked in 99% isopropyl alcohol to wipe your nails.
- Apply a top coat: If desired, apply a top coat to your nails and cure under the LED lamp for the recommended time.
- Protect your skin: To minimise the risk of skin cancer associated with UV exposure, use sunscreen or wear fingerless gloves during the manicure process.
- Clean your LED lamp: After you are done curing your nails, unplug the lamp and let it cool down. Wipe it down with a dry microfiber cloth. If needed, you can wet the cloth with water or a mild cleaner, then ensure it is dry before storing it away.
It is important to note that not all gel polishes are compatible with LED lamps, so always check the manufacturer's instructions before beginning the manicure process. Additionally, follow the recommended curing times for each coat of nail gel to avoid over-curing.

How to choose the right nail lamp
When choosing the right nail lamp, it is important to consider the potential health risks associated with the product. Both UV and LED nail lamps emit ultraviolet radiation, predominantly in the form of UVA, which is associated with a higher cancer risk. However, a 2014 study in JAMA Dermatology found that the level of UVA exposure associated with a gel manicure every two weeks is probably not high enough to significantly increase the risk of skin cancer.
LED nail lamps are generally considered safer than UV nail lamps as they deliver a much smaller dose of UV light more swiftly. LED lamps can cure gel polish faster than UV lamps, typically curing a layer of gel polish in 30 seconds, compared to the 2 minutes it takes for a UV lamp. Additionally, LED lamps tend to last longer, while UV lamps often need bulb replacements. However, not all gel polishes can be cured by an LED lamp, and some polishes are designed specifically for UV nail lamps. Therefore, it is important to check the compatibility of the gel polish with the type of lamp.
When choosing a nail lamp, it is recommended to follow the gel manufacturer's instructions for the proper light unit required to cure their gel product adequately. Some key features to consider when choosing a nail lamp include wattage, type of bulb, light wavelengths, power settings, timer settings, ease of use, and weight. For example, the SunUV Sun5 model offers a range of use options, including low heat and double power modes, and is suitable for both manicures and pedicures.
Additionally, it is important to prioritize the quality and safety of the nail lamp. SunUV lamps, for instance, are made with high-quality materials and are designed to be lightweight and simple to set up and use. They also offer a 1-year warranty on all lamps to ensure customer satisfaction.

The curing process
LED lamps, which emit a form of UV light, have become an increasingly popular alternative to traditional UV lamps due to their faster curing times and energy efficiency. LED lamps can cure a layer of gel polish in as little as 30 seconds, compared to the 2 minutes or more required by a UV lamp. This makes LED lamps a more time-efficient option, especially for those who want to cure both hands simultaneously. However, it is important to note that not all gel polishes are compatible with LED lamps, and some are specifically designed for use with UV lamps only. Therefore, it is crucial to check the compatibility of the gel polish with the type of lamp being used.
During the curing process, it is important to follow the recommended exposure times and take precautions to minimise UV exposure to the skin. This can include wearing protective gloves or using sunscreen on the hands and fingers. While the risk of skin cancer from using LED or UV lamps has been a concern, a 2014 study in JAMA Dermatology found that the level of UVA exposure associated with a gel manicure every two weeks is probably not high enough to significantly increase the risk of skin cancer. Nonetheless, it is always wise to be aware of the potential risks and take appropriate protective measures.
In addition to the curing time, the number of coats applied can also vary depending on the desired look and the specific products used. A typical manicure may involve a base coat, two colour coats, and a top coat, with each coat requiring curing under the light. Some polishes may also require a final curing step after all coats have been applied to ensure a durable and long-lasting manicure.
Overall, the curing process for gel nails involves the use of LED or UV light to harden and seal the gel polish onto the nail, with multiple coats and curing steps involved to achieve the desired finish and longevity. By following the recommended exposure times and taking appropriate precautions, individuals can safely enjoy the benefits of gel nails at home or in a professional salon setting.
