While gel nail polish is a popular choice for those wanting long-lasting, shiny nails, it's important to consider the potential risks associated with its use. One common concern is the strong smell that often accompanies gel nail polish, which can be off-putting and overwhelming for some people. In addition to the smell, the chemicals present in gel nail polish, such as formaldehyde, can be toxic and harmful to the health of your nails. The process of removing gel nail polish can also be damaging, as it typically involves sanding or filing, which can weaken and damage the natural nail bed. When deciding whether to use gel nail polish, it is essential to weigh the potential risks against the desired aesthetic outcome.

Removal of gel nail polish
Removing gel nail polish can be done in a few different ways. One way is to let your nails grow out and simply cut them once the gel is above the nail bed. However, this process can take up to six months for fingernails and 18 months for toenails. If you want the gel polish removed immediately, you can do so by using acetone, which is the most effective way to remove gel nail polish at home.
- Line your workspace with plastic wrap and put a thick towel on top. Acetone can damage surfaces, so it is important to cover your workspace.
- Put petroleum jelly on your cuticles and the skin around your nail to protect against the acetone, which can be harsh and drying.
- Rip cotton balls into pieces large enough to cover your nails. Smaller pieces help you avoid getting too much acetone on your skin and reduce waste.
- Buff your gel nail polish with a nail file to help the acetone soak in more easily.
- Soak the cotton ball pieces in acetone.
- Place each cotton ball on a nail and wrap it in plastic wrap or foil, or use a nail clip to keep the cotton in place. Ensure that the wrap is tight enough to keep the cotton in place but not too tight that it cuts off circulation to your fingers.
- After 5-10 minutes, remove the plastic wrap. Most or all of the gel nail polish should be gone.
- Remove any remaining gel nail polish with a warm washcloth. Gently scrub off the gel polish, rubbing only the nail and avoiding the surrounding skin.
- Wash your hands or feet with soap and water to remove the acetone.
- Moisturize your hands or feet.
Another method for removing gel nail polish is the double-bowl hot water and acetone technique. This method involves using a special bowl with a removable bottom filled with hot water to warm the acetone. After soaking your nails, you can use a triangle-shaped "scraper" to remove the gel polish.
It is important to note that acetone has a strong smell, so it is recommended to work in a well-ventilated area. Additionally, gel nail polish removers are also available as an alternative to using acetone, cotton balls, and foil. These removers are simple to use, require fewer tools, and are less damaging to your nails.

Toxic chemicals in gel nail polish
While gel nail polish is unlikely to have long-term negative effects on nail health if used occasionally, it's important to be aware of the potential risks associated with its toxic chemicals. The nail polish industry has evolved with longer-lasting polish techniques, but these innovations come with their own set of pros and cons regarding nail health and safety.
Gel nail polishes, like other types of nail polish, can contain toxic chemicals that can be harmful to your health. One of the most common concerns is the presence of formaldehyde, a known carcinogen recognized by the National Cancer Institute as a potential cancer-causing substance. Formaldehyde is also associated with causing allergic contact dermatitis, which can lead to skin irritation and other allergic reactions. Dibutyl phthalate (DnBP), another common ingredient in nail polishes, is an endocrine disruptor linked to hormone changes, diabetes, and thyroid irregularities. Toluene, often found in nail polishes, can cause eye irritation and damage to the kidneys and nervous system. Additionally, camphor, an oil used in some polishes, can be toxic if consumed orally.
The risks associated with nail polish go beyond its liquid form. Even after the polish has dried, the toxic chemicals it contains can still pose health risks. Your skin and nails can absorb these chemicals, allowing them to enter your body. Additionally, the removal process for gel nail polish often involves harsh chemicals like acetone, which can be drying and damaging to the nail plate, skin, and cuticles.
When choosing a gel nail polish, it's important to prioritize ingredient transparency. Look for brands that disclose their full ingredient list and avoid those that use vague or generic terminology. Opt for polishes that are marketed as "five-free," which means they are free from formaldehyde, toluene, dibutyl phthalate, formaldehyde resin, and camphor. There are also brands that go beyond and offer 7-free or 10-free options, excluding additional harmful substances. However, be cautious as some brands may replace common toxins with less studied chemicals, which could potentially have unknown risks.
To make informed decisions, you can utilize resources like the Environmental Working Group's (EWG) Skin Deep Database, which provides detailed assessments of cosmetic products, including nail polishes. Additionally, consider the frequency of use and the potential cumulative effects, especially if you're a nail technician or someone who paints their nails regularly. By being aware of the toxic chemicals in gel nail polish and choosing safer alternatives, you can enjoy beautiful nails without compromising your health.

Health risks of gel nail polish
Gel nail polishes may not have a strong smell, but they do come with other health risks. The curing process involves exposure to ultraviolet A (UVA) rays, which can cause skin ageing and DNA damage, potentially leading to skin cancer. The risk is similar to that of tanning beds, which also use UVA light. Studies have shown that UV nail polish dryers cause cell death, damage, and DNA mutations. This damage can occur after acute or chronic exposure, and the risk may increase over time with regular gel manicures.
The lamps used to cure gel nail polish are not the only concern. The polish itself contains chemicals that can be harmful, such as acrylate and methacrylate, which are known to cause allergic reactions like contact dermatitis and, less commonly, hives. Removing gel polish can also damage your nails, leading to issues such as cracking, peeling, and overall weakening of the nail plate. Improper removal can also increase the risk of nail infections.
To minimise the health risks associated with gel nail polish, it is recommended to limit UV exposure by applying sunscreen to your hands before curing and choosing alternative nail polish options that do not require UV light, such as dip powders. It is also crucial to protect your nails and cuticles during the application and removal process. Avoid cutting or pushing back your cuticles, as this can lead to inflammation and infection. Instead, moisturise your hands and nails and apply cuticle oil daily to maintain nail strength and reduce the risk of peeling.
Additionally, it is essential to be cautious when removing gel nail polish at home. Acetone, a common ingredient in gel nail polish removers, can be harsh and drying to the skin. Always follow proper removal procedures, such as using cotton balls soaked in acetone and wrapped in foil, to minimise the contact of acetone with your skin.

UVA rays in curing machines
Gel nail polishes are cured using ultraviolet (UV) light. UV curing is a process that uses UV light to convert or cure inks, adhesives, and coatings. The main components of a UV curing solution include resins, monomers, and photoinitiators. The photoinitiator is responsible for absorbing light and starting the reaction, which helps control the cure rate and depth. UV curing has proven to be helpful in a broad spectrum of industries and applications, including medicine, automobiles, cosmetics, food, science, education, and art.
UV curing systems can be categorised into spot-cure UV systems and UV conveyors. Spot-cure UV systems include short arc, high-power LED, and hand-held LED technology. UV conveyors, on the other hand, support a range of wavelengths and UV source types such as arc, microwave, and LED. UV LED curing systems offer increased productivity and benefits for curing processes using heat-sensitive substrates. They also eliminate the negative impact of traditional methods and provide an eco-conscious operation.
UV curing has specific applications in the cosmetics industry, particularly in artificial fingernails and gel nail polish. The use of UV-cured adhesive in gel nail polish eliminates the need for solvent removal, ratio mixing, and potential life concerns.
While UV curing technology offers many advantages, it is important to consider worker safety. UV measurement devices are crucial to UV operations by establishing and maintaining ideal performance quantities and ensuring worker safety.

Repairing damaged nails
Damaged nails can be frustrating and affect the overall appearance of your hands. Nails can become damaged in a variety of ways, including the overuse of gel or acrylic nail techniques, vitamin deficiencies, direct injuries to the nail bed, seasonal skincare concerns, nail biting, harsh manicures, and repeated use of nail polish remover.
If you have severe nail damage, it is recommended to consult a dermatologist for proper diagnosis and treatment. However, for mild to moderate nail damage, there are several simple ways to repair and improve the condition of your nails:
- Keep your nails clean and hydrated: Proper nail hygiene is essential for healthy nails.
- Avoid nail biting and picking: These habits can worsen damage and lead to further splitting.
- Follow a balanced diet: Your nail health is influenced by your overall well-being. Include foods rich in vitamins, minerals, and proteins, such as fruits, vegetables, lean proteins, and whole grains.
- Use a nail strengthener or hardener: These products help repair and strengthen damaged nails, improve their appearance, and promote nail growth.
- Keep your nails short: Shorter nails are less likely to catch on objects and break further.
- Soak your nails in oil: Oil helps to hydrate and nourish dry, damaged nails. You can soak your nails in oil for 10-15 minutes, massage it into your nails and hands, and then wear cotton gloves to seal in the moisture.
- Allow time for growth: Repairing damaged nails takes time and patience. It can take up to three months for nails to completely grow out and heal.
In addition to these general tips, if you have gel or acrylic nails, proper removal is crucial to avoid further damage. Avoid picking or prying off the polish, as this can hurt your nails. Instead, consider visiting a professional nail technician for safe and proper removal.
