Gel Nails: The Science Behind The Shine

what is in gel nails

Gel manicures have become increasingly popular in recent years, with many people opting for this long-lasting and durable alternative to traditional nail polish. Gel nails are formed of methacrylate compounds and photoinitiator compounds like benzoyl peroxide that adhere to the nail when exposed to UV light, creating a hard, glossy finish. This process, known as curing, takes only seconds and results in a manicure that can last for weeks without chipping or smudging. While gel nails are a popular choice due to their convenience and longevity, it is important to be mindful of the potential risks associated with the use of certain chemicals, such as skin irritation and nail brittleness.

Gel nail polish composition

Gel nail polish is a beautiful and durable alternative to traditional nail polish. It is made up of several chemical compounds, including methacrylate compounds, photoinitiators, and plasticizers. The primary function of these compounds is to provide adhesion, flexibility, and hardness to the nail polish.

Methacrylate compounds, such as methyl acrylate, are crucial for the adhesion of gel nail polish to the nail surface. Methyl acrylate is a colorless organic compound with a distinct acrid odor. While it is considered toxic, its presence in nail polish is in small amounts, and its potential health effects are still uncertain. On the other hand, methyl methacrylate, a related compound, has been banned due to its detrimental impact on health. Reputable nail polish brands, such as ORLY, ensure that their products do not contain this harmful compound.

Photoinitiator compounds, such as benzoyl peroxide, play a key role in the curing process of gel nail polish. When exposed to UV light, these compounds initiate a chemical reaction that causes the nail polish to harden and cure within seconds. This curing process is what gives gel nail polish its durability and long-lasting finish.

Plasticizers are also added to gel nail polish to provide flexibility and prevent brittleness. While the specific types of plasticizers may vary between different nail polish brands, their function is to ensure that the nail polish remains supple and resistant to cracking or chipping.

In addition to these primary components, gel nail polish may also contain other ingredients, such as pigments for color and various solvents. The exact composition of gel nail polish can vary slightly between different manufacturers, but the fundamental components remain similar.

The application process for gel nail polish typically involves multiple layers, including a base coat, color coat(s), and a top coat. Each layer is cured under a UV or LED light, which activates the photoinitiator compounds and hardens the polish. This process results in a glossy, durable finish that can last for 2-3 weeks or more without chipping or cracking.

Gel manicure process

The gel manicure process involves several steps to achieve the desired long-lasting, chip-resistant finish. Firstly, it is important to prepare the nails by cutting and shaping them to the desired length and ensuring they are clean. This can be done by soaking the hands in warm, soapy water, then trimming the cuticles and cleansing the hands. Next comes the application of a base coat to prepare the nails for the gel. The gel polish, consisting of methacrylate compounds, photoinitiators, and plasticizers, is then applied to the nails. The photoinitiators in the gel polish are crucial as they respond to specific wavelengths of light, typically UV or LED, and initiate the polymerization process that transforms the gel polish from a liquid to a solid state. The nails are then placed under a UV or LED lamp for curing, which hardens the polish and provides durability. The curing process may take around 30 seconds and can be repeated up to five times to ensure complete curing. Finally, a glossy top coat is applied to protect the gel polish from chipping, peeling, or fading, completing the gel manicure process.

It is important to note that while gel manicures offer long-lasting results, they can be hard on nails, potentially causing brittleness, peeling, and cracking if not properly cared for. To maintain nail health, it is recommended to give nails a break between gel manicures and to be cautious when removing the gel polish, as improper techniques can damage the nails.

Gel nail polish removal

There are several methods for removing gel nail polish, with the most common being the traditional acetone method. Other methods include using a gel nail polish remover, or simply letting your nails grow out and clipping them.

Traditional Acetone Method

The traditional acetone method involves using acetone, cotton balls or pads, aluminium foil, a cuticle pusher, and a nail file. Cuticle oil and a nail buffer are optional extras. It is recommended to work on one hand at a time, and to choose a well-ventilated area due to the strong smell of acetone. To avoid acetone stains, cover your work area with a cloth.

Firstly, use a coarse nail file to file down the gel top coat layer until it is no longer shiny and smooth. Next, soak a cotton ball in acetone and place it on your nail, then wrap foil paper around the cotton and your finger. Leave the plastic wrap on for 10-20 minutes. When you remove the foil, the gel nail polish should be mostly gone. Remove any remaining gel nail polish with a washcloth that you've run under warm water. Gently rub the nail to avoid irritating the surrounding skin.

Gel Nail Polish Remover

Gel nail polish removers are simple to use, require fewer tools, and are less damaging to your nails than the acetone method. Simply apply a thick layer of gel polish remover to your gel nails, being careful not to get it on your skin. After 5 minutes, the gel polish should start to peel, crack, bubble, or burst. Use a metal cuticle pusher or an orangewood stick to gently push off the gel polish from each nail.

Letting Your Nails Grow Out

The slowest method for removing gel nail polish is to simply let your nails grow out. Clip them once a week to help prevent the nails from catching on clothing and other objects. This method requires resisting the urge to pick at your gel nail polish, as this can damage your nails.

Other Methods

Other methods for removing gel nail polish include soaking your nails in very hot water for 5-6 minutes, which weakens the base coat so that it can be pushed off with a cuticle pusher. Another method is to soak your fingertips in acetone, which will break down the bonds of the gel polish.

Gel nail polish pros and cons

Gel nail polish has gained popularity in recent years as a better alternative to acrylic. It is durable, flexible, and versatile. It is also easy to use and almost indestructible. The hype around gel nail polish is not unfounded. However, there are some cons to gel nail polish.

Pros

Gel nail polish was made with the intention to mimic natural nails. It can be used to achieve a timeless French manicure or something more adventurous. It is long-lasting, with a high-shine finish, and can last up to three weeks without chipping. It is also budget-friendly, especially when used at home with DIY kits. The application is simple and there is no dry time.

Cons

The application and removal processes are more complex and time-consuming. The removal process can negatively affect nails, making them brittle, weak, and prone to peeling. Nails can also be thinned during the nail preparation process, as they are buffed before the gel is applied. It is recommended to give your nails a break between manicures and to apply a nail strengthener treatment to help strengthen them.

Composition

Gel nail polish is mostly composed of methacrylate compounds, photoinitiators, and plasticizers. It also contains Methyl Acrylate, a colorless organic compound with adhesive properties. While Methyl Acrylate is toxic, it has not been proven detrimental to health in the small amounts used in nail polish.

Gel nail polish vs acrylic nail polish

Gel nail polish has gained popularity in recent years as a better alternative to acrylic nail polish. It is durable, flexible, and easy to use. It is also versatile, allowing for DIY home kits in addition to being available at nail salons.

Gel nail polish is formed of methacrylate compounds and photoinitiator compounds like benzoyl peroxide. These compounds adhere to the nail when exposed to UV light, as opposed to drying like regular nail polish. The UV light causes the gel polish to harden and cure, resulting in a super shiny, long-lasting manicure. The manicure can last for around two to three weeks, and the nails dry instantly, frequently seeming more natural. Gel polish can be applied to natural nails, acrylics, and nail extensions.

Acrylic nail polish, on the other hand, is a mix of polymer and monomer. When combined, these ingredients create a gummy paste that is painted onto the nail with a brush. This paste then hardens and forms a durable layer over the natural nails. Acrylic nails are known for their strength and durability, and they can be shaped and filed to create various looks. However, they can be harsh on natural nails and may cause damage if not applied or maintained correctly. Acrylic nails are also more time-consuming to apply and remove than gel nails.

The best way to remove acrylic nails is by soaking them in acetone for 15-20 minutes, then filing and buffing off the remaining acrylic. Gel nails are also removed using acetone, which is applied to the nails, wrapped in foil, and left on for 10-15 minutes. This process is less harsh on the natural nails than the removal of acrylic nails, which can cause brittleness, peeling, and cracking.

In summary, gel nail polish is a more flexible, durable, and natural-looking alternative to acrylic nail polish. It is also easier to apply and remove, making it a popular choice for those seeking a long-lasting manicure. However, it is important to note that the UV lamps used to cure gel nail polish emit harmful UV rays, so proper protection is necessary.
