Unlike regular nail polish, gel nail polish cannot dry naturally. Instead, it needs to be cured under a UV or LED lamp to activate the chemical process that dries each coat of gel polish. This process typically takes 60 to 90 seconds, resulting in a manicure that is resistant to smudging and chipping for up to two to three weeks. However, the use of curing lamps has raised concerns about potential health risks, including UV exposure and the presence of chemicals in the gel polish that can cause allergic reactions and nail damage.

What You'll Learn
Gel nail polish requires curing under UV or LED light
Unlike regular nail polish, gel nail polish does not dry naturally. Instead, it needs to be cured under a UV or LED lamp. This process involves placing your nails under an LED or UV light to activate the chemical reaction that dries each coat of gel polish. The light initiates a process that allows the molecules in the gel to bind together and harden.
The curing time for gel nail polish varies from 60 to 90 seconds, resulting in a manicure that is resistant to smudging or chipping. However, it's important to note that the duration can depend on the type of gel nail polish used and the thickness of the applied layers. Thinner coats are recommended to ensure proper curing and reduce the curing time.
When purchasing a lamp for curing gel nail polish, it is essential to consider the specified drying time, which can range from 60 to 120 seconds. Additionally, the light intensity of the bulbs decreases over time, impacting the curing process. Regular bulb replacement is necessary, especially for frequent users.
While UV lamps have been traditionally used for curing gel nail polish, LED lamps have emerged as a popular alternative. LED curing is considered safer for the skin due to the absence of UV rays, which have been associated with an elevated risk of skin cancer. However, it is still recommended to take precautionary measures, such as applying sunscreen, regardless of the curing method chosen.

Non-UV gel nail polish can be used for easier drying
Non-UV gel nail polish is a convenient option for those who want to achieve a gel manicure look without the need for specialised equipment such as UV or LED lamps. While UV/LED lamps can speed up the curing process of gel nail polish, they are not necessary for all gel polishes. Some gel nail polishes are formulated to dry and harden without the use of these lamps, offering an easier and more accessible option for at-home manicures.
Non-UV gel nail polishes typically involve a similar application process to regular nail polish. It is recommended to gently shake the bottle of non-UV gel nail polish before use to ensure the ingredients are well mixed. Then, carefully apply two thin coats of the polish to clean, dry nails, allowing a few minutes between each coat for the polish to set. After the final coat, wait for about five minutes before applying a non-UV gel top coat. It is important to allow the nails to dry completely before proceeding with any other steps.
To expedite the drying process, quick-dry nail polish spray can be used. This spray helps the solvents in the polish to evaporate more quickly, reducing the overall drying time. When using quick-dry spray, it is advisable to hold your hands over a towel or newspaper and maintain a distance of about six inches from your nails while they are still wet. This process can be repeated for the other hand to ensure even and efficient drying.
While non-UV gel nail polish offers convenience and ease of application, it is important to note that the drying time may vary depending on the specific product used and the thickness of the coats applied. Thinner coats tend to dry faster and cure more effectively than thicker coats. Additionally, non-UV gel manicures may not last as long as those cured with UV/LED lamps, typically offering 7 to 10 chip-free days compared to 12 to 21 days with light-cured gel polish.
Overall, non-UV gel nail polish provides a viable option for individuals who want the benefits of a gel manicure without the need for specialised lamps. By following the recommended application and drying procedures, individuals can achieve long-lasting, glossy nails with minimal effort and maximum convenience.

Curing lamps can cause skin damage and cancer
Curing lamps are used to dry and cure gel nail polish. These lamps emit ultraviolet (UV) radiation, which has been linked to skin cancer. While the risk of cancer from occasional nail lamp use is low, studies have shown that the UV rays emitted by these lamps can penetrate the skin and cause permanent damage over time.
UVA radiation, in particular, has been associated with a higher cancer risk. It can lead to premature skin aging and cause damage to DNA in skin cells, potentially resulting in genetic defects or mutations. This can eventually lead to various types of skin cancer, including basal cell carcinoma, squamous cell carcinoma, and melanoma.
To put this risk into perspective, a 2014 study in JAMA Dermatology found that the level of UVA exposure from a gel manicure every two weeks was probably not high enough to significantly increase the risk of skin cancer. However, it is still important to be aware of the potential dangers and take precautions when using curing lamps.
To safeguard yourself, it is recommended to apply a broad-spectrum (UVA/UVB) sunscreen to your hands before exposure to UV light. Additionally, you can wear fingerless gloves during your manicure to provide added protection from UVA radiation. It is also crucial to follow the recommended precautions and guidelines provided by the lamp manufacturers.
While non-UV gel nail polishes are available, they may not provide the same long-lasting and glossy finish as traditional gel polishes. These non-UV options typically require more time to dry, similar to regular nail polish.

Gel nail polish contains chemicals that can cause allergic reactions
Gel nail polishes are popular for their long-lasting wear and glossy finish. However, it's important to be aware that these products contain chemicals that can cause allergic reactions in some individuals. The main culprits are the ingredients monomers and photoinitiators, which belong to the chemical families known as acrylates and methacrylates. These substances are classified as skin sensitisers, meaning that if they come into contact with the skin, they can trigger allergies.
The British Association of Dermatologists (BAD) has issued warnings about the potential risks associated with gel nail polishes. In 2018, they reported a significant increase in cases of allergic skin reactions linked to (meth)acrylate chemicals found in these products. The issue is not limited to gel polishes but extends to artificial nails, acrylic nails, and gel colour nails as well. The rise in at-home manicures during the pandemic may have contributed to this spike, as people are more likely to experience adverse effects when using at-home kits due to a lack of professional experience.
The allergic reactions associated with gel nail polishes can vary in severity and presentation. Some individuals may experience immediate contact dermatitis, characterised by reddened, swollen, and itchy skin around the manicure or under the nail tip. Others may develop a delayed hypersensitivity reaction, with symptoms including nails loosening or falling off, severe rashes on the face, neck, and upper chest, and even respiratory difficulties. These reactions can be long-lasting and may lead to sensitivity to acrylates in other contexts, such as dentistry or orthopaedic surgery.
To mitigate the risk of an allergic reaction, it is crucial to follow safety precautions when using gel nail polishes. This includes performing a patch test before a manicure to check for any potential allergies. Additionally, it is essential to avoid direct skin contact with the nail product during application and curing. Nitrile gloves are recommended for nail technicians, with frequent changes every 30 minutes to minimise the risk of exposure. For at-home users, following the manufacturer's instructions, using the recommended UV or LED lamp, and ensuring proper ventilation are key to reducing the chances of an adverse reaction.
While gel nail polishes offer long-lasting colour and shine, it is important to be mindful of the potential health risks associated with their use. By taking the necessary precautions and being vigilant about product safety, individuals can reduce the likelihood of experiencing an allergic reaction.

It is important to allow time between manicures for nail recovery
While some sources claim that nails do not need a break from product application as they are not made up of living cells, and that with consistent appointments and correct product application, the health of the natural nails should never be affected, it is still important to allow time between manicures for nail recovery. This is especially important if your nails have been damaged by incorrect processes, over-filing, or incorrect preparation and application. A technician may advise you to allow your nails to recover before your next appointment, and the length of the break will depend on the health of your nail and the specific damage caused. Nails grow about one-tenth of an inch (2.5 millimeters) each month, and at that rate, it can take about 3 to 6 months to completely replace a nail. If the damage is near the top of the nail, you may only need to wait a few weeks.
It is also important to be cautious of any allergies that may be caused by the gel nail polish. Potential allergens often used in gel products include TPO (Trimethylolpropane triacrylate) and HEMA (2-Hydroxyethyl Methacrylate). If you notice red, swollen, and itchy skin around your nails, it is recommended to consult a technician as soon as possible and have the product removed. An allergy can only be confirmed through an allergy test with a dermatologist.
Additionally, the light intensity of your light bulbs will get lower over time, and if you do not change the bulbs in your lamp, they will not be able to cure your gel nails properly. If you are using your lamp on a daily basis, the bulbs should be changed every two to four months. Therefore, it is important to allow time between manicures to change the bulbs in your lamp to ensure that your gel nails are cured effectively.
