Gel Nail Color: The Science Behind Long-Lasting Manicures

how does gel nail color work

Gel nail colour is a type of manicure that uses a specific type of nail polish—gel nail polish—that is cured with a UV or LED nail lamp to create a shiny, long-lasting manicure that doesn't require extensive drying time. The gel formula allows for deeper, richer pigment saturation than traditional polish, resulting in more vivid and intense colours that resist fading and yellowing. The application process involves a gel base coat, the gel nail colour, and a gel top coat. The interconnected polymer network that gel polishes form gives them their chip resistance and staying power. However, it's important to note that gel nail colour can change colour or fade due to various factors, and proper preparation and aftercare are crucial for maintaining the colour and health of the nails.

Gel nail polish application

Gel nail polish is cured with a UV or LED lamp to create a shiny, long-lasting manicure that doesn't require extensive drying time. The application process is similar to that of traditional nail polish, but with a few key differences. Firstly, it is important to ensure that the nails are properly prepared. This includes buffing and wiping down the nails with alcohol to allow the polish to adhere better and prevent lifting and peeling. Nails may also need to be trimmed and shaped with a file.

Once the nails are prepped, the gel base coat is applied, followed by the gel nail polish in the desired colour, and finally, a gel top coat. Each coat is cured under a UV or LED lamp for between 30 seconds and two minutes, depending on the product. The light triggers a chemical reaction that hardens the gel polish, creating a smooth, high-gloss finish. The gel formula allows for deeper, richer pigment saturation, resulting in more vivid and intense colour compared to regular nail polish.

It is important to apply the gel polish evenly and to use the correct top coat to ensure adequate protection and prevent chipping. The thickness of the gel polish layers also matters; if they are too thin, the colour may fade, and if they are too thick, the product may lift or chip. The time it takes to apply gel nails can vary depending on the experience of the nail technician, the condition of the nails, and the complexity of the design.

Gel manicures typically last for up to three weeks without chipping or losing their shine. To remove the gel polish, the nails must be soaked in acetone, which can dry out the nails. It is important to take care of the nails after a gel manicure to prevent thinning and weakening. This includes hydrating the hands with cuticle oil or hand cream and avoiding exposure to certain spices, ingredients, and makeup that can cause discolouration.

Gel nail polish removal

There are two main methods to removing gel nail polish: the traditional method and with a gel nail polish remover. The traditional method involves using acetone, which is the most effective way to remove gel nail polish at home. It is important to note that acetone has a strong smell, so it is recommended to work in a well-ventilated area. To protect your work area from acetone stains, cover it with a cloth or plastic wrap.

  • Work on one hand at a time.
  • Cut 10 squares of aluminum foil, big enough for each fingertip.
  • Tear off 10 pieces of cotton balls that fit just the nail bed of each nail.
  • Soak the cotton balls in acetone.
  • Place the cotton balls on your nails and wrap the aluminum foil around them to hold them in place.
  • Let them soak for 10-20 minutes.
  • Gently push off the gel using a cuticle pusher or orangewood stick. If the gel is resistant, rewrap the nail and wait another 5 minutes.
  • Buff your nails with a nail buffer to smooth the surface.
  • Finish by applying cuticle oil and a rich hand cream to rehydrate your nails.

The other method is to use a gel nail polish remover, which is faster and gentler. This method does not require an acetone bath and takes only 5 minutes.

Gel nail polish chipping

Gel nail polish is a thin brush-on formula designed for high performance and a glossier finish than regular nail polish. It is based on acrylic polymers, and the polymerization is triggered by light. The interconnected polymer network that these compounds form gives gels their chip resistance and staying power.

However, gel nail polish is not immune to chipping. One of the main reasons for gel nail polish chipping is improper nail preparation. For instance, if the nail is too smooth, the polish will have nothing to hold on to and will chip. To avoid this, it is recommended to buff the nails to create a slightly rough surface for better adhesion. Additionally, the nail plate should be degreased with a nail cleaner or acetone to remove any oils. If the nail plate is oily or problematic, applying a primer or acid-free primer can enhance product adhesion.

Another reason for gel nail polish chipping is incorrect product application. For example, applying gel polish too close to the cuticles can cause lifting and chipping. Thick layers of gel polish can also result in an uneven cure, wrinkling, and chipping. Instead, thin layers are recommended. Each layer of polish should seal the free edge of the nail to prevent air pockets and premature chipping.

Other factors that can contribute to gel nail polish chipping include old or improperly stored gel polish, mixing products from different brands, and soft or bendy nails. To prevent chipping, it is important to check the expiration date and store nail products properly. Using products from the same brand can ensure better adhesion between layers. For those with soft or bendy nails, using a builder gel or a rubber base coat underneath the gel polish can provide additional support and reduce the likelihood of chipping.

Gel nail polish discolouration

Gel nail polishes are cured under UV light to set and typically last two weeks without chipping. However, there are several reasons why gel nail polish may discolour. Firstly, lower-quality gels are more prone to discolouration and will be more brittle. Similarly, if the gel was exposed to sunlight, it may have gone bad, so it is best to store nail polish in a cool, dry place.

Additionally, some gel nail polishes are designed to change colour under certain conditions. These include thermal gels that change colour according to temperature and gels that change colour under UV light.

Discolouration can also occur due to overexposure to UV light, which can happen if you spend a lot of time in the sun or use self-tanners. Certain chemicals can also cause discolouration, such as those found in cleaning supplies, makeup, skincare products, hair dye, and food with high acid content. Smoking can also cause discolouration, especially in the hand that holds the cigarette.

To prevent discolouration, it is recommended to use a top coat, ensure proper nail preparation, and avoid applying sunscreen or makeup to the nails.

Gel nail polish vs. regular nail polish

Gel nail polish and regular nail polish have a lot in common, but there are some key differences to be aware of. Both are polymeric coatings applied on top of natural nails, but the type of polymers they contain differ. Regular nail polish is mostly nitrocellulose-based and dries via solvent evaporation, whereas gel nail polish is acrylic polymer-based and is hardened under a special LED or UV lamp.

The application process for gel and regular nail polish is very similar. Nails are trimmed and shaped, and a base coat is applied before the colour. However, after the gel base coat is added, the nails are cured under a lamp to set the polish. This gives gel manicures their renowned longevity, with gel polish lasting twice as long as regular polish – up to three weeks. Gel polish is also more resistant to scratches and chipping.

Despite the benefits of gel polish, it is more costly and time-consuming, and it can be more damaging to nails. The removal process for gel polish is more labour-intensive and can leave your nail beds exposed to damage if not done correctly. It is recommended that you get gel polish removed by a professional to avoid harming your nails.

Ultimately, the choice between gel and regular nail polish comes down to personal preference. If you like to change your nail colour frequently, regular nail polish may be the best option. However, if you want a long-lasting, chip-resistant manicure, gel polish is the way to go.
