Gel nail polishes are popular for their quick-drying time and long-lasting wear. The curing process involves using a UV or LED lamp to seal and harden the gel nail polish, creating a solid layer of colour that won't chip easily. While gel nails can be cured at home, it requires patience and the correct technique to achieve optimal results and maintain client safety. This includes understanding curing times, which vary depending on the brand and type of lamp used, and ensuring proper lamp usage to avoid potential heat spikes. Additionally, it is important to avoid applying gel too close to the skin and cuticles, as this can lead to issues during removal.

What You'll Learn
The dangers of curing gel nails
Curing gel nails involves using a UV or LED lamp to seal and harden the gel nail polish. This process, known as polymerization, causes the molecules in the gel polish to bond together, forming a solid layer of colour that is durable and long-lasting. While this method of manicure has become increasingly popular, there are some dangers associated with curing gel nails that are important to be aware of.
One potential danger of curing gel nails is the exposure to ultraviolet (UV) radiation. Traditional UV lamps emit UV radiation, which can be dangerous for your health. However, it is important to note that the level of UV radiation emitted by these lamps is relatively low, and exposure time is typically less than 5-10 minutes per service. Additionally, there are now more focused and energy-efficient options available, such as LED lamps, which utilise more violet light wavelengths and cure faster than UV lamps.
Another issue that can arise during the curing process is ineffective adhesion. If the gel nail polish is not cured properly, it can lead to under-cured gel sitting on the nail plate for an extended period. This can result in adhesion issues, where the bottom layer residing on the nail plate has not adhered correctly. Consequently, this can cause potential skin sensitivities, irritation, or allergies. To avoid this, it is crucial to ensure proper gel curing by following the recommended guidelines, using the correct lamp, and applying the gel in thin and even coats to allow for adequate curing.
Heat spikes during the curing process can also be a concern, especially for clients with weak or damaged nails. The warmer the gel is initially, the faster the photoinitiators will react to the UV/LED lights, resulting in a warmer sensation for the client. While most of the time, heat spikes do not impact the health of the nail bed, it is important to mitigate the temperature by using low heat modes, flash curing, and communicating with the client to ensure their comfort.
Additionally, it is worth noting that some gel nail polishes are misleadingly marketed as gel polishes when they are, in fact, regular nail polishes that air-dry. These polishes will not cure under a lamp, and it is essential to read the label carefully before purchasing to ensure it specifies that it is a non-UV gel polish.

Using non-UV gel polishes
If you want to avoid using UV light to cure your gel nails, you can opt for non-UV gel nail polishes. These are sometimes referred to as "gel-like" nail polishes. While regular gel nail polish will not dry without a UV light or LED lamp, non-UV gel polishes can be air-dried.
When purchasing a non-UV gel polish, make sure the label specifies that the polish does not require a UV light or LED lamp to cure. If it does not specify this, it is likely that the polish will not cure without a light or lamp. You can speed up the drying process by applying thin, even coats.
There are also quick-drying nail polish sprays available that can be used to dry non-UV gel polishes faster. To use a nail polish spray, lay your hand out on a flat surface covered with newspaper or paper towels. Hold the can of nail polish spray about 7 inches (18 cm) away from your hand and spray a light coat over your nails while the polish is still wet. Leave your nails to dry for the time listed on the bottle, which is usually 5 to 10 minutes. You can also try using canola oil cooking spray in the same way as a nail polish spray. The oil will thin out the nail polish, helping it to dry faster. After your nails are dry, wash your hands with soap and water to remove any residual spray.
Some non-UV gel polishes are cured by natural light, with the photoactivator in the top coat activated by sunlight rather than UV light. Examples of brands that sell non-UV gel polishes include Essie, SH (or Sally Hansen), Zoya, OPI, Mooncat, Holo Taco, ILNP, and Cirque Colors.

The importance of curing each coat
Curing gel nails is an important process that ensures optimal results and client safety. Curing each coat of gel polish helps to achieve a flawless finish and prolongs the manicure's longevity. Here are some key reasons why curing each coat is essential:
- Adhesion and Durability: Curing each layer of gel polish ensures proper adhesion to the nail plate. The base coat, colour coat, and top coat need to be cured adequately to promote better adhesion and durability. This prevents issues like chipping, peeling, or lifting, ensuring the manicure lasts longer.
- Avoiding Under-Curing: Under-curing occurs when gel polish hasn't cured completely, even though it may appear solid on the top layer. This can lead to ineffective adhesion and potential skin sensitivities or allergies. By curing each coat, you reduce the risk of under-curing, protecting the health of your client's nails and skin.
- Optimal Appearance: Curing between multiple thin coats of gel polish ensures optimal appearance. This method helps achieve a smooth, high-shine finish. It also prevents issues like bubbling, lumpiness, or rippling, which can occur when gel polish is applied too thickly or due to incorrect curing procedures.
- Client Comfort: Curing each coat properly also takes into account the client's comfort. By utilising low heat modes, flash curing, and communicating with the client, you can ensure their comfort during the curing process. While warmth is normal, excessive heat can cause discomfort, and proper curing techniques help mitigate this issue.
- Longevity: Curing each coat of gel polish contributes to the overall longevity of the manicure. Proper curing ensures that the gel polish hardens and sets correctly, allowing it to last for up to 2 weeks with proper care. This helps maintain the integrity of the manicure and prevents premature chipping or peeling.
- Safety: Curing gel polish with a UV light emits ultraviolet radiation, which can be harmful to health. However, using a UV/LED lamp recommended by the brand can mitigate potential risks. Additionally, alternative curing methods, such as non-UV gel polishes or quick-drying nail polish sprays, offer safer options without the need for UV exposure.
In summary, curing each coat of gel nail polish is crucial to achieve a long-lasting, aesthetically pleasing manicure while also prioritising client safety and comfort. Proper curing techniques ensure adhesion, durability, and optimal appearance while reducing potential health risks associated with under-curing or UV exposure.

How to test if your gel is curing properly
Curing gel polish requires some training to master. However, with the right technique and patience, you can learn to cure your gel polishes perfectly every time.
Gel polish curing is the process of using a specially designed UV or LED light to seal and harden the gel nail polish on your nails. This process 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.
To test if your gel is curing properly, try the following:
- Take a bead of the gel (the volume/thickness of gel you think you'll be using) and apply it to a form.
- Cure the gel for the recommended time, which is usually around one minute.
- Check the underside of the gel once it's cured. If the underside is still liquid, then it hasn't cured properly.
- Ensure you are applying the gel in thin and even coats. Remember, the UV/LED lamp lights need to penetrate not only the thickness of the product but also the pigment within the gel. If the gel is applied too thickly, the light won't be able to power through those layers and cure the product.
- Check the irradiance value of your lamp. The irradiance value refers to the intensity of UV/LED light emitted by the lamp and is measured in milliwatts per square centimetre (mW/cm2). Different brands of gel polish require specific irradiance values for proper curing.
- If you have any concerns that your lamp is no longer effective, perform a cure test on a form.
- Follow the manufacturer's directions for curing time. Some gels may only need 10 seconds, while others could take up to 45 seconds.
- Cure each coat under the lamp, including the base and top coats, for long-lasting results.
If your gel polish is not curing properly, it might be due to one of the following reasons:
- The gel is applied too thickly, preventing the light from curing the product.
- The lamp is not powerful enough to cure the gel polish effectively.
- The curing time is too short, and the gel needs more time to harden completely.
By following the above steps and troubleshooting tips, you can ensure that your gel polish is curing properly and will result in a long-lasting, chip-resistant manicure.

The risks of gel-curing press-on nails
Gel-curing press-on nails is a trending method for ensuring long-lasting manicures. However, there are some associated risks that you should be aware of before attempting this technique.
One of the main risks is the potential for nail damage. When press-on nails are gel-cured, they cannot simply be popped off. Instead, they must be soaked in pure acetone, which can be time-consuming and lead to nail brittleness. Attempting to forcefully remove them can cause significant damage to the nail plate, nail bed, cuticle, and nail matrix (the nail's growth center).
Another risk is exposure to UV radiation, which can be harmful to your health. While UV lamps are commonly used to cure gel polish, they emit ultraviolet radiation. This can be a concern, especially if you get your nails done frequently. To mitigate this risk, you can opt for alternative curing methods with less UV exposure, such as using non-UV gel polishes or quick-drying nail polish sprays.
In addition, there is a risk of developing an allergic reaction or contact dermatitis if the gel comes into contact with the skin and is not cured correctly or completely. This can lead to swelling, pain, inflammation, and separation. Opaque or dark-colored nails may also contribute to this risk, as the UV light might not be able to penetrate and cure the gel properly, potentially causing allergies or irritation.
Furthermore, infection is another possible complication of gel-curing press-on nails. If there are gaps or openings between the press-on and the natural nail, moisture can enter and lead to bacterial infections. Properly cleaning the nails with alcohol and ensuring there are no bubbles during the curing process can help reduce this risk.
It is important to carefully follow the instructions provided by professionals and be aware of these potential risks when attempting to gel-cure press-on nails at home.
