The importance of using a lamp
Curing gel nail polish is a process that requires the use of a lamp to achieve a long-lasting, chip-resistant manicure. While some gel polish brands claim that their products can air-dry without the need for a lamp, most professional technicians recommend using one to ensure optimal results. The purpose of the lamp is to facilitate the polymerisation process, which involves bonding the molecules in the gel polish together to create a solid layer of colour that resists chipping and wear.
The type of lamp used can vary, with UV and LED lamps being the most common options. Both types of lamps are effective, but they have distinct characteristics. LED lamps tend to cure gel polish faster and produce less heat, making them a suitable choice for individuals with sensitive skin or nails. On the other hand, UV lamps offer more power and often provide a wider working area, which some technicians prefer. Ultimately, the choice between a UV or LED lamp depends on personal preference and specific needs.
When curing gel nail polish, it is essential to follow the manufacturer's directions for cure time, as it can vary between brands. Typically, the base coat is exposed to the lamp for 45 seconds, the colour layer for 60 seconds, and the topcoat for a maximum of 90 seconds. It is important not to over-cure the gel polish, as this can lead to excessive hardening, making removal challenging. Additionally, it is recommended to cure each coat under the lamp, including the base and top coats, to ensure proper sealing and long-lasting results.
The positioning of the lamp is also crucial. It should be placed at a distance of around 2 inches from the nails to allow for the proper formation of the gel base coat and topcoat. Furthermore, it is important to remember that gel polish should be applied in thin layers to ensure proper curing. If the layers are too thick, the lamp may not be able to cure the gel polish effectively, resulting in lumpy or bubbled polish.
In conclusion, using a lamp is essential for curing gel nail polish. It ensures the proper bonding of the gel molecules, resulting in a durable and chip-resistant manicure. By selecting the appropriate type of lamp, following the manufacturer's instructions for cure time, and considering the positioning and thickness of the gel polish layers, individuals can achieve optimal results and maintain the longevity of their manicure.

The difference between UV and LED lamps
Curing gel nail polish involves using a UV or LED lamp to solidify and strengthen the gel nail polish. This process, known as polymerization, creates a durable layer of colour that resists chipping and wear. The duration of the curing process depends on your nail type and the type of lamp used, ranging from a few seconds to several minutes.
LED lamps cure gel polish faster than UV lamps. Typically, an LED lamp cures a layer of gel polish in 30 to 35 seconds, while a UV lamp takes around 2 minutes to do the same job. This makes LED lamps more attractive to those who want to save time. However, not all gel polishes can be cured by an LED lamp, and some polishes are designed specifically for UV nail lamps. Therefore, it is important to check whether the brand of gel polish you are using is compatible with an LED lamp.
The main difference between UV and LED lamps is the type of radiation and wavelength range they emit. UV lamps emit ultraviolet light with a short wavelength of around 100 to 400 nanometers, while LED lamps emit light from light-emitting diodes with a longer wavelength of 365 nanometers. The shorter and narrower wavelength of UV light contributes to its longer curing process.
Another difference between the two types of lamps is their power and exposure times. Higher-wattage bulbs can cure gel polish faster, and LED lamps tend to have higher wattages than UV lamps. Additionally, some gels require higher lamp wattages and longer exposure times to dry properly.
In terms of cost, LED lamps are typically more expensive than UV lamps. However, LED lamps tend to last longer, while UV lamps may require frequent bulb replacements.

How to prepare your nails
Preparing your nails before applying gel polish is crucial for achieving a long-lasting and flawless manicure. Here is a step-by-step guide on how to prepare your nails for gel polish application:
Remove Old Polish: Start by removing any existing nail polish, lacquer, or gel from your nails. It is important to ensure that your nails are clean and free of any residue before proceeding to the next steps.
Push Back and Trim Cuticles: Gently push back your cuticles using an appropriate tool, such as a cuticle pusher or orangewood stick. Be careful not to cut or trim your cuticles, as this can lead to pain and potential infection. After pushing back your cuticles, rinse your hands in warm water.
Shape and Buff Your Nails: File and shape your nails to your desired length and shape. You can use a nail file to gently shape the edges and create your preferred nail shape, such as square, round, or oval. Once shaped, gently buff the surface of your nails to smooth out any bumps or ridges. This step helps create an even surface for the gel polish to adhere to.
Cleanse and Dehydrate: Use a nail cleanser or dehydrator to remove any remaining oils, dust, or debris from your nails. This step is important because any residue or moisture on the nail plate can interfere with the adhesion of the gel polish. Be sure to use lint-free wipes, as cotton wool may leave fibres on your nails.
Apply a Base Coat: Always start with a base coat to help the gel polish adhere properly to your nails. Apply a thin, even layer of a high-quality base coat to each nail, capping the free edge of the nail. This protective base layer will help prevent chipping and peeling.
Cure the Base Coat: After applying the base coat, it's time to cure your nails under a UV or LED lamp. Follow the manufacturer's instructions for the recommended cure time, which is usually around 30 to 45 seconds. This step is crucial for ensuring the base coat is thoroughly cured.
Remember, proper nail preparation is key to achieving the best results with gel nail polish. Taking the time to prepare your nails will help ensure a long-lasting, chip-resistant manicure that looks professional and flawless.

The role of base coats
Curing gel nail polish involves using a UV or LED lamp to seal and harden the polish onto your nails. This process, known as polymerisation, creates a durable layer of colour that resists chipping and wear. The duration of the curing process varies depending on your nail type and the type of lamp used, ranging from a few seconds to several minutes.
The role of a base coat is to act as a protective barrier between the nail and the coloured polish. It helps the manicure last longer by preventing pigments from staining your nails and shielding them from external factors, such as humidity, that could weaken them. A base coat also helps the gel polish adhere better to the nail, so it won't peel off prematurely.
One thin base coat is recommended every time you apply gel nail polish. After applying the base coat, cure the nails under an LED or UV lamp (adjusting the time accordingly) to seal and harden the base coat. The base coat should be exposed to the lamp for around 45 seconds.
The type of base coat you choose depends on the polish you're using. For example, if you're using Green Flash™ gel polish, you would use the Green Flash™ Vitamin-Enriched Base Coat. This base coat is formulated with up to 84% plant-based ingredients and is packed with nutrients, vitamins, and minerals, making it ideal for fragile or tired nails that need a boost.
In addition to choosing the right type of base coat, it's important to prepare your nails properly before applying the base coat. This includes washing your hands, filing your nails, pushing back and trimming your cuticles, buffing your nails, and priming your nails with an acid-free primer.

The final steps of applying a top coat
Before applying the top coat, it is crucial to wipe off any sticky or tacky residue on the nail surface. This can be done using a cotton ball or cleanser wipe. Additionally, buff the top layer of colour to smooth out any imperfections and ensure a clean surface. This step is important as it helps the top coat adhere better.
Next, apply the top coat itself. Ensure that it covers the entire nail, including the edges, to create a perfect seal. The top coat serves as a protective sealer, preserving the colour underneath and adding a luminous finish. It is recommended to cure the top coat for a maximum of 90 seconds under a UV or LED lamp. This duration may vary slightly depending on the brand of polish, so always refer to the manufacturer's instructions. Over-curing the top coat can lead to excessive hardening, making it challenging to remove later.
Position the lamp approximately 2 inches away from your nails during curing. After curing, simply wipe off any remaining tacky residue with a cotton ball dipped in alcohol, and your manicure is complete!
To maintain the health and longevity of your manicure, it is recommended to apply cuticle oil daily, especially after washing your hands. Additionally, wear gloves during daily tasks and avoid soaking your nails in hot water for extended periods. Following these steps will ensure your gel manicure remains in top condition for as long as possible.
