The popularity of gel manicures has raised concerns about the potential health risks associated with the ultraviolet (UV) lamps used to cure the nail polish. UV lamps emit ultraviolet A (UVA) radiation, which is linked to an increased risk of skin cancer and accelerated ageing. However, the nail industry has utilised UV lamps for over 20 years, and some studies suggest that the UV exposure from nail lamps is minimal and safe when used according to instructions. The FDA and PBA's Nail Manufacturers Council on Safety (NMC) support this claim, stating that typical nail salon UV exposures are within permissible daily limits. Nevertheless, health experts advise that UV light damages skin cells, and a recent study found that UV nail dryers can harm DNA and cause mutations in human cells. The use of LED lamps, which also emit UV light, is another option, but they are more expensive and not suitable for all gel nail products. While the occasional gel manicure may not pose a significant danger, precautions such as applying broad-spectrum sunscreen to the hands beforehand can be taken to minimise potential risks.

| Are UV nail lamps safe? | According to the FDA, nail dryers with UV light are safe when used according to the instructions for use. However, health experts agree that UV light causes damage to skin cells, and there is a small but growing body of research suggesting that regular use of UV nail lamps could accelerate aging and increase cancer risk. |
| Precautions | Dr. Marchbein and Dr. Campbell recommend wearing manicure gloves with UPF (Ultraviolet Protection Factor) during gel manicure services. The Skin Cancer Foundation recommends applying a broad-spectrum (UVA/UVB) sunscreen to hands 20 minutes before your hands are exposed to UV light. |

The UV lights used in gel nails emit ultraviolet radiation, predominantly in the form of UVA, which is associated with a higher cancer risk
The UV lights used in gel nails emit ultraviolet radiation, predominantly in the form of UVA rays. This is concerning because exposure to ultraviolet radiation is known to cause skin damage, including skin cancer.
UVA radiation has been linked to premature skin ageing and an increased risk of skin cancer. In fact, a 2017 study found that some nail melanomas contained mutations with a UV signature, suggesting that UV exposure may be a risk factor for nail melanoma. Additionally, a new study published in Nature Communications in 2023 found that the UV lights commonly used in gel manicures can damage DNA and cause cell mutations. This study exposed both human and mouse subjects to UV light in 20-minute increments and found that anywhere from 20 to 30% of cells died in the first 20-minute session; after three sessions, about 65 to 70% of cells died.
While the level of UVA exposure associated with a gel manicure every two weeks is probably not high enough to significantly increase the risk of skin cancer, it is still wise to be aware of the potential risks. Repeated exposure to UV nail lamps over many years can lead to skin cancer on the nail, around the nail bed, and on the fingers. Therefore, it is recommended to limit the number of gel manicures per year.
To protect yourself, you can apply a broad-spectrum (UVA/UVB) sunscreen to your hands before your UV light exposure. You can also wear manicure gloves with a UPF (Ultraviolet Protection Factor) rating or cover your hands and fingers with a garment that has a UPF rating, such as a glove with the tips cut off, a shirt, or a scarf.

A study found that UV lights used in gel manicures can damage DNA and cause cell mutations
A study by researchers at the University of California, San Diego, has found that the ultraviolet (UV) light-emitting devices used to cure gel manicures may pose a significant public health concern. The devices, which are a common fixture in nail salons, typically use a particular spectrum of UV light (340-395nm) to cure the chemicals used in gel manicures.
The study, published in Nature Communications, found that exposure to UV light from nail dryers caused mitochondrial and DNA damage in human cells, resulting in mutations with patterns that can be observed in skin cancer. The researchers exposed human and mouse cells to UV light from nail dryers, irradiating them one, two, or three times for durations of up to 20 minutes. A single 20-minute irradiation resulted in 20-30% cell death, while three consecutive exposures caused 65-70% cell death.
The study's corresponding author, Professor Ludmil Alexandrov, noted that there were already reports in medical journals of people who get gel manicures very frequently, such as pageant contestants and estheticians, developing rare cancers in the fingers. However, there was a lack of molecular understanding of the impact of these devices on human cells. The study's findings suggest that the radiation emitted by UV nail polish dryers may cause cancers of the hand and increase the risk of early-onset skin cancer.
While the study raises concerns about the safety of UV nail dryers, it is important to note that further research is needed to quantify any increased risk of cancer and the frequency of use that may lead to adverse effects. Additionally, alternatives to this cosmetic procedure are available, and consumers can make informed choices based on their comfort level with the potential risks.

The key ingredient in gel manicures, methacrylates, can trigger allergic reactions if it comes into contact with uncured skin
The popularity of gel manicures has soared in recent years, but concerns have been raised about the potential health risks associated with the process, particularly regarding the use of ultraviolet (UV) lamps. One of the key ingredients in gel manicures is methacrylates, which can trigger allergic reactions if it comes into contact with uncured skin.
Methacrylates are chemicals that are used in gel nail polishes to harden the polish and give it its durable finish. However, if these chemicals are not properly cured or hardened during the manicure process, they can leak into the skin and cause an allergic reaction. This reaction typically manifests as painful peeling, swelling, blisters, and a severe, itchy rash on the skin. In more severe cases, the nails can loosen, and the skin can become infected, requiring medical attention.
The risk of an allergic reaction to methacrylates is not limited to the hands and nails. Dermatologists have reported cases of skin irritation in other areas of the body, such as the neck and eyelids, due to the transfer of uncured chemicals from the nails to other body parts. This can occur through touching or scratching, as the allergen can be moved from the fingernails to more sensitive areas of the body.
To minimize the risk of an allergic reaction, it is recommended to seek the services of a fully trained nail technician who follows the manufacturer's instructions for curing times and uses properly maintained equipment. Additionally, individuals can apply a barrier cream, such as Vaseline, around the nails before the manicure to prevent direct contact between uncured chemicals and the skin.
It is worth noting that even with proper precautions, some individuals may still develop an allergy to methacrylates. The reasons for this are not fully understood, as some people can use gel manicures for years without issue before suddenly developing an allergy. If an allergic reaction occurs, it is advised to consult a medical professional for guidance on treatment and future nail care.

The UV light exposure from gel nails can cause brown spots on hands
The UV light exposure from gel nails can indeed cause brown spots on hands, along with other skin issues. UV nail lamps emit high volumes of ultraviolet radiation in a short space of time, and frequent exposure to these UV rays can lead to solar lentigines, or "liver spots", on the skin.
UV nail lamps are used to speed-dry regular manicures and are required to set gel manicures. The gel nail polishes need UV light to harden and cure the polish. However, this process can cause cumulative damage to the skin. The amount of damage caused depends on the strength of the UV rays, the length of exposure, and whether the skin has any protective covering.
To protect against UV exposure, it is recommended to apply sunscreen or wear gloves with the fingertips cut out. Some people also choose to wear UV gloves, which can be useful for protection outside as well. It is also important to note that the devices are not regulated, and each proprietary gel polish has its own lamp and curing time recommendation, which may not be followed by salons.
Therefore, it is important to consider the potential risks of UV exposure when deciding on gel manicures. While gel manicures done infrequently are unlikely to cause significant harm, regular exposure to UV rays from gel nails can lead to brown spots and other skin issues, including wrinkles, thinning of the skin, increased bruising, and potentially skin cancer.

Regular manicures are safer as they can air-dry naturally, without the use of UV lights
The use of UV light in gel nail treatments has been a cause for concern, with some studies suggesting that it could be harmful to health. The lamps emit ultraviolet A (UVA) radiation, which is associated with a higher cancer risk. The Skin Cancer Foundation recommends applying a broad-spectrum (UVA/UVB) sunscreen to hands before exposure to UV light during a manicure.
However, it is important to note that the UV exposure created by nail lamps is considered minimal by some experts, and there is ongoing debate about the safety of these devices. Some studies suggest that the risk of developing non-melanoma skin cancer from nail lamp use is much lower than other risks associated with exposure to UV light. The FDA also maintains that nail dryers with UV light are safe when used according to the instructions.
Nevertheless, the best way to avoid any potential harm from UV light during a manicure is to opt for a regular manicure that air-dries naturally. Regular manicures do not require the use of UV lights to set the polish, and therefore, you can avoid any potential risks associated with UV exposure. Allowing nails to air-dry is the safest option, and it is also possible to use a fan or blower without UV lights to speed up the process.
While gel manicures are popular due to their durability and long-lasting nature, the potential health risks associated with UV light exposure during the curing process cannot be ignored. By choosing a regular manicure that dries naturally, you can enjoy a safer and potentially healthier alternative to gel nails. This method eliminates the need for UV light exposure and provides a simple and effective way to maintain nail health and avoid any potential harm to the skin.
