The importance of UV light in the drying process
The use of ultraviolet (UV) light in the drying process, also known as UV curing, is a crucial and innovative technique that offers numerous advantages over traditional drying methods. UV curing involves exposing materials to concentrated, high-intensity UV light, which initiates a photochemical reaction that instantly hardens or cures the material. This process is widely used across various industries, including automotive, printing, and flooring, due to its efficiency, consistency, and environmentally friendly nature.
One of the key benefits of UV curing is the significant time savings it provides. UV light instantly dries or cures materials, allowing for faster production processes and reducing the time required for drying. For example, in the automotive industry, UV curing is used to harden and strengthen finishes on interior parts, and most products treated with UV radiation are cured and ready to handle within two minutes. This helps keep assembly lines moving efficiently without causing bottlenecks.
UV curing also provides a superior finish compared to traditional drying methods. When certain polymers, inks, or coatings are exposed to UV light, a process called cross-linking occurs, resulting in a hardened and strengthened finish. This finish is consistent, clean, and crisp, enhancing the appearance and durability of the cured material. For instance, in the printing industry, UV curing is used to create glossy postcards, magnets, and calendars with a vibrant print colour that dries much faster and more consistently than infrared heat drying.
Additionally, UV curing is environmentally friendly as it eliminates the need for solvent-based products and the associated evaporation of solvents into the air. Conventional heat and air drying methods rely on solvent evaporation, which can lead to a significant reduction in the coating thickness and the release of environmental pollutants. In contrast, UV curing produces no toxic odours, and the lack of evaporation ensures that there is no loss in coating thickness, resulting in a more sustainable process.
Furthermore, UV curing technology ensures a strong bond between the base coat and the gel polish in nail care applications. The UV light establishes a reliable connection between the two layers, contributing to the durability and longevity of the manicure. The base coat, when cured under a UV lamp, acts as a protective shield, strengthening and enhancing the natural nails while providing a smooth surface for the colour coat. This initial step is crucial for achieving a professional and long-lasting manicure.

The difference between UV and LED lights for drying
A base coat is an essential component of a gel manicure. It acts as a protective shield, strengthening and enhancing your natural nails while providing a solid foundation for gel polish colours. The base coat also helps maintain nail health and integrity. Typically, a base coat is applied to the nails and cured under a UV/LED lamp for about 60 seconds.
UV and LED lamps have the same function: they react with polishes to instantly dry and adhere the colour to the nail. However, there are some differences between the two.
The term "UV" refers to a type of light emission in the ultraviolet range, invisible to the human eye, with a wavelength between 100nm and 400nm. On the other hand, "LED" refers to a device made up of light-emitting diodes capable of emitting light. A LED lamp is a lamp with several of these light-emitting diodes. It is possible to have a lamp equipped with LED lights that emit UV rays.
Incandescent lamps, also known as "UV lamps", use fluorescent tubes. They tend to consume more energy, generate more heat, and may require longer exposure times to dry the gel. In contrast, LED lamps are electroluminescent and are known as "cool" lamps. They consume less energy, produce less heat, and generally require shorter exposure times.
The other differentiating factor between drying lamps is the wavelength range of emitted light. UV light is typically emitted between 100 and 400nm, but not all gels cure at the same wavelength. Some gels may require a higher wavelength for optimal curing.
Power and exposure time are also notable differences between lamp types. Depending on the gel's composition, some require higher lamp wattages and longer exposure times to dry properly.
It is important to note that UV and LED lamps used for manicures emit UVA rays, which can pose health risks with frequent and prolonged exposure. However, the French Academy of Medicine has recommended precautionary principles and the application of sunscreen before the manicure session to address these concerns.

How to get a great gel nail finish
Preparation
Before you start, make sure your nails are prepped and ready to go. Cut your nails to your desired length and file them to smooth out any rough edges. Glass nail files are a great option as they are gentler than emery boards.
Next, apply cuticle oil to your nail beds. This will help to soften your cuticles so you can push them back gently. Remember to wash your hands afterward and ensure there is no oil left on your nails before you start the gel process, as this can cause your gel nails to lift.
Now, buff your nails. This step is important as it will remove any natural oils on your nails that can build up and reduce the lifespan of your gel manicure. After buffing, clean your nails with an alcohol wipe to remove any remaining residue and oils.
Base coat
Apply a thin layer of base coat to your nails. The base coat will help the gel polish adhere better and create a smooth surface for the colour to be applied. Cure your nails under a UV lamp for up to 30 seconds, or 60 seconds if you are using a LED lamp.
Gel nail polish
Now it's time for the colour! Apply a thin layer of gel nail polish, painting all the way to the tip of your nail. Don't worry if it looks streaky, as this is normal for the first layer. Cure your nails under the UV light, and then repeat this process for a second layer. You can add a third coat if you feel it's necessary, but it's usually not needed.
Top coat
Seal your gel nail polish with a layer of clear top coat. This will protect the colour and add shine. Cure your nails under the UV light for 2 minutes, or 30 seconds if you are using a LED lamp.
Finishing touches
If there is any tackiness on your nails, you can remove it by gently blotting each nail with a cotton ball dipped in isopropyl alcohol. Finally, buff your nails to smooth out any imperfections and wipe away any gel polish on your cuticles with an acetone-soaked cotton ball.
Removal
When it's time to remove your gel manicure, it's best to go to a professional. Gel nail polish is hard and sturdy, and removing it yourself can damage your nails. However, if you want to remove it at home, start by filing off the top layer of the gel and the top coat with a nail file. Then, soak cotton balls in acetone and place them on top of each nail, wrapping them tightly with tin foil. Leave them for 20-40 minutes, and then remove the foil and push off the gel with a cuticle stick. Wash your hands and apply cuticle oil to your skin and nails to restore moisture.

Tips to speed up the drying time
Typically, a base coat under a UV light takes 60 seconds to dry. Here are some tips to speed up the drying time:
Thin Coats
Apply thin, even coats to speed up the drying process. Thick coats take longer to dry because the solvents take longer to evaporate. Allow each layer to dry completely before applying the next coat.
Fast-Drying Topcoat
Apply a quick-drying topcoat to seal the nail polish and speed up the drying time. Make sure to apply the topcoat after the final layer of nail polish has dried completely.
Accelerating Spray
Use an accelerating spray to speed up the drying process. These sprays use alcohol-based solvents that help evaporate the nail polish more quickly. They also create a protective layer on top of the nail polish, preventing smudges or dents. However, not all nail polishes react well with accelerating sprays, and some formulas may be too thick or require a longer drying time for an accelerating spray to be effective.
Nail Dryer
Nail dryers are an excellent option for speeding up the drying process. They come in different sizes and types, including portable fans and full-size machines, and use cool air to speed up the drying of your nails.
Cold Water
Dipping your nails in cold water can help set the nail polish quickly. After applying the final layer of nail polish, wait a few minutes, then dip your nails in a bowl of ice water for 2-3 minutes. Alternatively, you can use ice water to soak your unpainted nails before applying nail polish to shorten the drying time.
UV or LED Lamp
UV or LED lamps use specific wavelengths of light to cure the nail polish, helping it to dry faster. The light reacts with photoinitiators in the polish to create a hardened, durable finish. However, be mindful that frequent exposure to UV radiation from these lamps can potentially increase your risk of health issues.

Troubleshooting common drying issues
Insufficient UV lamp power: One common issue is using a UV lamp that does not emit UV light at the correct frequency or with sufficient power. It is important to use a high-quality lamp that can produce the necessary wavelength for proper curing. Verify the wattage requirements of your gel polish and compare it to the wattage of your UV lamp.
Thickness of application: Applying the gel polish too thickly can result in incomplete drying, as the UV light may not penetrate through all layers. It is recommended to apply thin coats of gel polish to allow for better curing.
Hand position: Incorrect hand placement inside the UV lamp can hinder the drying process. Ensure that all five nails are fully exposed to the UV light, and check your lamp for any grooves or indicators that can guide proper hand positioning.
Lamp issues: Your UV lamp may not be strong enough to cure certain gel polishes, especially if it is an older model. Ensure that all bulbs in your lamp are functioning properly, as worn-out bulbs may not provide sufficient curing power.
Humidity and temperature: Environmental factors such as high humidity or low temperature can slow down the drying process.
Exposure time: Ensure that you are exposing the base coat to the UV light for the recommended duration. Typically, a base coat will take around 60 seconds to dry under a UV lamp.
It is also important to note that UV rays from the lamp can cure the product in a matter of seconds, so be sure to follow the specific instructions provided by the manufacturer. Additionally, always avoid contact with sunlight, as it can lead to hardening and colour changes in the nail polish.
