UV gel nails are a type of manicure that uses a gel-based polish that is hardened under a UV or LED light. The process of hardening the gel polish under UV light is called polymerization, where small molecules called monomers join together to form long chains, known as polymers. The UV light activates photoinitiators in the gel formula, which absorb the light energy and cause the monomers to link together, forming polymers. This results in the hardening of the gel polish, creating a strong and durable coating on the nails. UV gel nails have become increasingly popular due to their durability and long-lasting shine, with the gel polish resisting chips and scratches for up to three weeks.

What You'll Learn
The process of polymerization
UV-cured gel nail products have become increasingly popular in the world of nail care due to their durability and long-lasting shine. The process of polymerization involves transforming from a liquid to a solid state.
Polymerization is a chemical process in which small molecules, called monomers, join together to form long chains, known as polymers. In the case of UV-cured gel nail products, the monomers are liquid substances that, when exposed to ultraviolet (UV) light, undergo a rapid polymerization process, transforming into a solid, durable material. This process is known as cross-linking and results in the hardening of the gel polish, creating a strong, durable coating on your nails.
UV light plays a crucial role in the polymerization process of UV-cured gel nail products. The UV light activates photoinitiators, which are added to the gel formula. When the photoinitiators absorb the UV light, they become energized and break down into free radicals. These free radicals then react with the monomers in the gel polish, triggering them to link together and form long polymer chains.
Each layer of gel polish is applied thinly to ensure even curing. After each layer is applied, the nails are placed under a UV lamp, which emits UV light. The level of UV radiation emitted by these lamps is relatively low, and exposure time is normally less than 5-10 minutes per service.
Builder gels are used to add strength and structure to the nails. They are applied in layers and can be used to build up the nail to the desired thickness. Similar to gel polish, builder gels also contain photoinitiators that react to UV light to initiate the polymerization process. As the UV light shines on the builder gel, the photoinitiators in the formula begin the cross-linking process, transforming the gel into a solid, durable material.

UV light and photoinitiators
UV gel nails are a type of nail manicure that uses a gel-based polish that is hardened under a UV or LED light. The process of hardening the gel polish under UV light is called polymerization, a chemical process in which small molecules called monomers join together to form long chains, known as polymers.
UV light plays a crucial role in the polymerization process of UV-cured gel nail products. When the nails are placed under a UV lamp, the light activates photoinitiators, which are added to the gel formula. Photoinitiators are chemicals that, when exposed to UV light, become energized and initiate a chain reaction that causes the monomers in the gel polish to link together, forming polymers. This process, known as cross-linking, results in the hardening of the gel polish, creating a strong and durable coating on the nails.
The UV light used in gel nail services emits a relatively low level of UV radiation, and exposure time is normally short, less than 5-10 minutes per service. However, there are still some concerns regarding the potential risks of UV exposure during gel nail manicures. The UV light can contribute to skin ageing and potentially increase the risk of skin cancer. To mitigate these concerns, it is recommended to wear UV protection gloves that only expose the fingernails or apply sunscreen to the hands before placing them under a UV lamp.
The use of photoinitiators in the gel formula is essential to the polymerization process. When the photoinitiators absorb the UV light, they break apart into free radicals, which then react with the monomers in the gel polish, triggering them to link together and form long polymer chains. This cross-linking process transforms the gel polish from a liquid to a solid state, resulting in the desired durable and long-lasting shine of UV gel nails.

Gel vs. shellac
UV-cured gel nail products have become increasingly popular due to their durability and long-lasting shine. The process of applying gel nails involves polymerization, which is a chemical process in which small molecules, called monomers, join together to form long chains, known as polymers. When exposed to ultraviolet (UV) light, the monomers undergo a rapid transformation into a solid, durable material.
Now, let's compare gel and shellac:
Gel nails are available in two forms: hard gel and soft gel. Hard gel is applied with a brush and is stronger than soft gel. It can be used to add length to the nail, whereas soft gel is applied like traditional nail polish and cannot be used for extensions. Both types of gel nails are cured under a UV or LED lamp and can last for up to three weeks. Removal of gel nails involves soaking and filing, which can sometimes damage the surface of the nails.
Shellac, on the other hand, is a hybrid of gel and traditional nail polish. It combines the durability and hardness of gel with the colour and shine of regular polish. Shellac is a patented brand, created by Creative Nail Design (CND), and it cures under UV or LED light as well. It lasts for up to two weeks and is more prone to chipping than gel. However, shellac is easier to remove than gel, and it can be done in minutes without harsh scraping, using an acetone remover.
In summary, the main differences between gel and shellac are the colour options, the ability to extend nail length, and the removal process. Gel nails offer more colour choices and can be used for extensions, but they may be more difficult to remove. Shellac, while offering fewer colour options and not suitable for extensions, is easier to remove and still provides the benefits of durability and shine.

Gel vs. acrylic nails
UV gel nails are a type of manicure that uses a specific type of nail polish—gel nail polish—that is cured with a UV nail lamp to create a shiny, long-lasting manicure that doesn't require extensive time to dry. Traditional nail polish usually chips within two to three days, whereas gel polish lasts for several weeks.
Now, onto the differences between gel and acrylic nails. Gel nail polish is applied to your nail and then cured with a UV lamp. This results in a super shiny, durable nail polish that can last for weeks without chipping off like traditional nail polish. It dries within 60 seconds, meaning you don’t have to wait around at the salon or worry about smudging your polish. Acrylic nails, on the other hand, are created by blending acrylic polymer powder with a liquid monomer. The two are mixed in a bowl to form a gummy paste that is then painted onto the nail with a brush and hardens when it hits the air. Acrylic nails are typically used as an enhancement to lengthen the nail and provide a much harder shell, which is ideal for people with brittle or soft nails, or those who pick at their nail polish.
A hybrid gel-acrylic nail approach is also an option, which provides a more natural-looking result with added strength. This approach involves applying a gel nail first and then overlaying it with acrylic. This technique is preferred by some because it means the acrylic never touches the nail bed, which is beneficial since acrylics are known to be damaging. Additionally, gels are usually the most affordable option and tend to look the most natural as they create a thinner coating over the nail.
In terms of removal, the best way to remove both acrylic and gel nails is with an acetone soak. Start by clipping off the ends of your nails with a nail clipper, then file and buff the tops of your nails to remove the nail polish. Next, apply cuticle oil or petroleum jelly to protect your skin during the soak. To remove acrylic nails, saturate a cotton ball with acetone nail polish remover and place it on top of the nail, then wrap a piece of aluminum foil around each nail and wait for 20 minutes.
While gel and acrylic manicures are two of the most popular salon nail services, they have some key differences. Ultimately, choosing the best nail option comes down to personal preferences and individual needs.

Health and safety concerns
UV gel nails are a type of manicure that uses a gel-based polish that is cured and hardened under a UV light. This process, known as polymerization, involves the transformation of liquid gel polish into a solid, durable material through the joining of small molecules called monomers to form long chains, known as polymers.
While UV gel nails offer a long-lasting, high-shine manicure, there are several health and safety concerns associated with their use:
Potential DNA Damage and Cancer Risk
One of the primary concerns with UV gel nails is the potential risk of DNA damage and skin cancer. Studies have found that the UV radiation emitted by nail lamps can damage DNA and cause mutations in human cells. This has raised alarms in the dermatology community, as frequent gel polish users have reported rare cancers on their nails and fingers, which have been attributed to UV exposure. It is important to note that the link between gel manicures and skin cancer is not yet conclusively proven, and large-scale epidemiological studies are needed to accurately quantify the risk.
UV Radiation Exposure
The UV lamps used in gel manicures emit ultraviolet A (UVA) radiation, which is associated with an increased risk of skin cancer. While the exposure time during a gel manicure service is typically short (less than 5-10 minutes), the cumulative effect of regular manicures can add up over time. Additionally, the intensity of UV rays can vary, and some lamps may emit more powerful rays than natural sunlight.
Safe Removal
It is important to remove gel polish safely to avoid damaging the natural nails. Gel polish should not be peeled away from the nails, as this can cause harm to the natural nails. Instead, it should be safely removed at home using 100% pure acetone or by a nail technician.
Allergic Reactions
As with any cosmetic product, there is a risk of allergic reactions to the ingredients in gel nail products. While less common, some individuals may experience skin irritation, redness, or other adverse reactions.
To mitigate these health and safety concerns, some precautions can be taken, such as using sunscreen or wearing fingerless gloves during manicures to protect the skin from UV radiation exposure. Additionally, individuals can opt for alternative nail services that do not require UV light, such as traditional nail polish or LED-cured gel polishes.
