What You'll Learn
Gel nail polish is cured under UV or LED light
The curing process is what sets gel nail polish apart from regular nail polish. While regular nail polish dries on its own, gel nail polish is cured under UV or LED light. This process involves applying a thin layer of the gel substance to the nail and exposing it to UV or LED light, which triggers polymerization and causes the gel to harden and adhere to the nail. The UV or LED light activates the photoinitiators in the gel nail polish formula, such as benzoyl peroxide, which then break down into free radicals that initiate the chemical reaction of polymerization. This reaction results in the formation of a stiff, shiny, and durable layer on the nail.
The curing process of gel nail polish contributes to its longer-lasting and more durable nature compared to regular nail polish. The hardened gel layer is less prone to chipping, peeling, or breaking, ensuring that the manicure stays fresh and intact for longer. This advantage has contributed to the popularity of gel nail polish, as it offers a convenient and low-maintenance option for those seeking a long-lasting manicure.
The curing process under UV or LED light also allows for customization and creativity in nail design. The gel layer can be easily dissolved using acetone, making it possible to create intricate designs and experiment with different colours and finishes. This has further fuelled the trend of gel nail polish, as it provides a versatile platform for self-expression and artistic exploration beyond the limitations of traditional nail polish.
While the UV or LED light curing process offers numerous benefits, it is important to consider the potential risks associated with UV radiation exposure. The American Academy of Dermatology recommends taking precautions, such as applying sunscreen or wearing opaque gloves, to protect the hands from the ultraviolet lamp's radiation during the curing process. Additionally, it is advisable to carefully choose a reputable nail salon that prioritizes sterile tools and safe practices to minimize any potential health risks.
In conclusion, the curing of gel nail polish under UV or LED light is a crucial aspect of its application process, contributing to its durability, versatility, and popularity. By understanding the chemistry behind the curing process and taking the necessary precautions, individuals can confidently enjoy the benefits of gel nail polish while making informed choices to ensure the health and safety of their nails and hands.

It is made of methacrylate compounds
The popularity of gel nail polish has been rising since its re-introduction to the market in the late 1990s. It is a better alternative to acrylic nails and is extremely durable and flexible. Gel nail polish is formed of methacrylate compounds and photoinitiator compounds like benzoyl peroxide. The monomers that the photoinitiator pushes to polymerize are a mixture of various methacrylates. Hydroxyethyl methacrylate (HEMA) is a major component of many gel polishes. There may also be a couple of other small methacrylates in the formula, as well as oligomers or polymers with reactive methacrylate groups.
The methacrylate compounds in gel nail polish are what give it its strong yet flexible nature. The interconnected polymer network these compounds form gives gels their chip resistance and staying power. By tweaking the combination of building blocks, the same light-triggered reaction can be used to create polymer coatings with a range of properties. The hardening process involves the repeated application of a thin layer of substance on the nail, exposing it to ultraviolet light, and repeating the process, as UV radiation cannot penetrate a relatively deep layer of gel nail polish.
It is important to note that there are certain risks associated with using gel nail polish, such as exposure to radiation. The American Academy of Dermatology recommends applying a generous layer of sunscreen to the palms of the hands before treatment to prevent damage from the ultraviolet lamp used for drying the gel. Additionally, it is recommended to limit the contact area of acetone and other nail polish removers with your skin as much as possible.
Overall, gel nail polish is a great option for those seeking a durable, flexible, and natural-looking alternative to traditional nail polish. With its wide range of colors and finishes, quick-drying time, and ability to strengthen and protect natural nails, it is no surprise that gel nail polish has become a staple in the nail industry.

It contains photoinitiators like benzoyl peroxide
The composition of gel nail polish is what sets it apart from regular nail polish. It is made up of a thicker, gel-like substance that is cured under UV or LED light to create a hard, durable layer on the nails. This is in contrast to regular nail polish, which is typically a thinner, lacquer-like substance that dries on its own. The curing process of gel nail polish involves exposing it to ultraviolet light, which is a type of high-energy radiation.
Gel nail polish contains photoinitiators like benzoyl peroxide, which is one of the most common photoinitiators used. These photoinitiators are crucial to the hardening process of gel nail polish. When exposed to UV light, benzoyl peroxide breaks down into active molecules called free radicals. These free radicals then trigger a chemical reaction, causing the dissolved components of the gel nail polish to form a stiff and shiny layer on the nail. This process is known as polymerization, where monomers link up to form polymer chains. The interconnected polymer network gives gel nails their chip resistance and long-lasting nature.
The use of benzoyl peroxide and other photoinitiators in gel nail polish has raised some safety concerns due to the potential risks associated with UV radiation exposure. It is recommended to carefully choose a reputable nail salon and ensure the use of sterile tools during the application process. Additionally, applying sunscreen to the palms of the hands or wearing opaque gloves with the tips cut off can help protect the skin from UV exposure during the curing process.
While gel nail polish offers durability and a natural look, it is important to be aware of the potential risks and take the necessary precautions. Taking breaks between applications and properly removing gel nail polish can also help maintain healthy nails. The development of safer curing methods and formulas has been a focus for companies, ensuring that gel nail polish remains a popular choice for those seeking long-lasting and aesthetically pleasing manicures.
