What You'll Learn
UV light dries nails quickly
UV nail lamps emit ultraviolet rays with a wavelength of 365nm. The curing time depends on the type of gel polish and the lamp used. Typically, it takes between one and two minutes for the gel polish to dry under a UV lamp, although some lamps may take up to seven to ten minutes. The wattage of the lamp is a crucial factor, with higher wattage resulting in shorter curing times. Additionally, the number of beads in the lamp and the distance between the nail and the lamp also influence the curing time.
To use a UV lamp for curing gel polish, place your painted nails flat under the lamp, leaving a slight gap between each finger. Ensure that only your fingernails are exposed to the UV light, and follow the manufacturer's instructions for timing. It is recommended to cure each layer of gel polish completely before applying the next one.
While UV nail lamps offer the advantage of quick drying times, there are some concerns about the potential risks associated with UV exposure. Frequent exposure to UV radiation from nail lamps may increase the risk of skin cancer, photoaging, and other skin damage. To mitigate these risks, it is advisable to use LED nail lamps, which emit less UV radiation, or apply sunscreen to your hands before a gel manicure.
It is worth noting that non-UV gel polishes are available, which do not require UV light to dry. These polishes are convenient for at-home use and provide long-lasting results similar to traditional nail polishes.

The process is called polymerisation
Gel manicures are a popular choice for those seeking long-lasting nail polish that dries quickly and efficiently. Unlike regular nail polish, gel polish requires a UV or LED lamp to cure and dry the polish. This process is known as polymerisation.
Polymerisation is a chemical process in which smaller molecules, known as monomers or building blocks, chemically react to form larger molecules or macromolecules. These macromolecules then collectively form a polymer. The monomer molecules can be all alike or different, depending on the desired characteristics of the final product. In the context of nail polish, polymerisation causes the molecules in the gel polish to bond together, creating a solid layer of colour that is resistant to chipping and wear.
There are several methods of polymerisation, including addition polymerisation (also known as chain-growth polymerisation) and condensation polymerisation. In addition polymerisation, new monomer units are added to the growing polymer molecule through double or triple bonds. This process occurs in three distinct steps: chain initiation, propagation, and termination. Chain initiation can be started by a reactive initiation molecule, such as a radical, cation, anion, or organometallic complex. Propagation involves the addition of monomer units to the growing polymer chain, and termination occurs when the polymerisation process is stopped.
Condensation polymerisation, on the other hand, involves the formation of a molecule of a simple compound, often water, at each step of the process. This type of polymerisation usually occurs in the presence of catalysts, which can influence the structural details and properties of the resulting polymer.
The curing time for gel nail polish depends on various factors, including the wattage and type of nail lamp, as well as the specific gel polish being used. Higher wattage lamps generally result in shorter curing times. The distance between the nail and the lamp bulb also plays a role, with closer proximity leading to higher intensity and shorter curing times. While there is no definitive answer, a general guideline is to start with 5 minutes and adjust the duration as needed.

UV lamps emit UV-A and UV-B rays
Gel manicures have become increasingly popular, and for good reason. The use of ultraviolet (UV) light to dry nails is an innovation that allows for a faster manicure process and long-lasting results. While this technology has improved the efficiency of nail treatments, it's important to understand the potential risks associated with UV exposure.
UV lamps, specifically those used for nail curing, emit UV-A and UV-B rays. These lamps produce ultraviolet radiation with wavelengths of 365 nanometers (nm). This range of UV light is known as UV-A, which has longer wavelengths that can penetrate the middle layer of the skin, called the dermis. Prolonged exposure to UV-A rays can contribute to photoaging and an increased risk of skin cancer.
Additionally, UV lamps may also emit small amounts of UV-B radiation. While UV-B rays have shorter wavelengths and lower intensity compared to UV-A, they can still cause skin damage. UV-B rays are considered more harmful due to their ability to damage the DNA in skin cells more directly. Consistent and unprotected exposure to both UV-A and UV-B rays can lead to melanoma and other skin cancers.
To mitigate the risks associated with UV lamp use, it is recommended to take several precautions. Firstly, always maintain a safe distance between your nails and the lamp, typically around 2 inches. Additionally, you can apply sunscreen or wear UV-absorbent gloves to protect your hands from UV exposure. It is also important to monitor any changes in your skin, such as new moles or alterations in existing ones, as this may indicate potential skin damage or melanoma.
While UV lamps can pose certain risks, it's important to note that the Food and Drug Administration (FDA) in the USA has deemed the adverse effects of UV lamps to be low-risk when used properly. By following safety guidelines and being mindful of exposure time, you can enjoy the benefits of UV nail curing while minimizing potential harm.

UV light can cause skin damage
Gel nail polishes require UV or LED nail lamps for curing. The UV light emitted by these nail lamps is in the ultraviolet range of 365nm. The higher the wattage of the nail lamp, the shorter the curing time. For example, a 36W nail lamp can cure gel polish in 1-2 minutes, while a 9W nail lamp will take about 6 minutes.
While UV nail lamps are convenient, they can also be harmful to your skin. Ultraviolet (UV) radiation from the sun can cause wrinkles, premature ageing, and skin cancer. UV radiation from the sun is the primary cause of skin cancer, but UV light from tanning beds is just as harmful. Exposure to sunlight during the winter months puts you at the same risk of exposure as during the summertime. Cumulative sun exposure causes basal cell and squamous cell skin cancer, while episodes of severe blistering sunburns, usually before the age of 18, can also increase your risk of developing skin cancer later in life.
UVA and UVB rays from the sun can damage your skin. UVB rays have slightly more energy than UVA rays, and they directly damage the DNA in skin cells, causing sunburns and contributing to skin cancer. UVA rays have lower energy, but they penetrate your skin more deeply and cause genetic damage to cells on the innermost part of your top skin layer, where most skin cancers occur. Over time, UVA rays also lead to premature ageing and skin cancer.
To protect yourself from UV radiation, you can take several precautions. Apply sunscreen with an SPF rating of 30 or higher to your hands before using a gel nail manicure. You can also use UV-absorbent gloves to further protect your hands from harmful UV rays. Additionally, you can look for sunscreen products that offer "broad-spectrum protection," which means they protect against both UVA and UVB rays.

Non-UV gel polishes are available
While gel nail polishes are popular for their long-lasting, chip-resistant, and shiny finish, they typically require curing with a UV or LED lamp. This process, known as polymerisation, seals and hardens the gel nail polish, creating a solid layer that remains intact for an extended period. However, it's important to note that not all gel nail polishes depend on UV or LED lamps for curing.
One option for non-UV gel polishes is to use a gel top coat over regular nail polish. Brands like Chanel offer clear gel top coats that cure with natural light, adding a glossy, gel-like finish to your manicure. CND's Vinylux, for example, provides a shiny gel-like appearance that lasts for about a week. Similarly, Nails Inc's pale grey gel nail polish combines a plump, shiny finish with nourishing flower extracts for strong and healthy nails.
Another approach is to choose gel polishes that utilise LED curing instead of UV light. LED curing offers a faster and safer alternative to UV light, as LED lamps emit visible light instead of ultraviolet rays. Green Flash, for instance, offers over 60 shades of non-toxic gel polish that can be cured using LED light. Their formula is free from harsh chemicals and fragrances, providing a healthier option for your nails.
It's worth noting that non-UV gel polishes may not last as long as traditional UV-cured gel manicures. While UV-cured gel polishes can remain chip-free for up to 12 to 21 days, non-UV gel polishes typically offer 7 to 10 chip-free days. Additionally, some non-UV gel polishes may require specific application techniques or base and top coats to achieve optimal results.
