Gel nail polishes are increasingly popular for their quick-drying time and long-lasting wear. However, curing gel nail polish typically requires a UV or LED light, depending on the polish. While some have considered using alternative light sources, such as an LED flashlight or a phone flashlight, these are not generally effective for curing gel nails. This is because most non-specialized LED and phone flashlights do not emit the required wavelength of light, which is typically below 400 nm for gel polish curing. Additionally, the use of UV light for curing gel nails has raised health concerns due to the emission of ultraviolet radiation. As a result, some people opt for non-UV gel polish alternatives or air-dry manicure kits that do not require any light curing.

The dangers of curing gel nails with UV light
It is not recommended to use your phone's flashlight to cure gel nails. While some high-quality LED flashlights may emit the right wavelength of light to cure gel nail polish, most non-specialized LED flashlights and phones don't emit waves below 400 nm, which is typically needed to cure gel nails.
Curing gel nails with UV light comes with certain risks. Firstly, under-curing is a common issue, and it can lead to skin irritation and allergies for both clients and nail professionals. UV-cured products can harden and be filed when they are only 50% cured, and it is challenging to determine the level of curing just by looking at or filing the nails. This means that clients could continue to wear under-cured nails for weeks, potentially exposing themselves to harmful substances.
Secondly, exposure to UV radiation is known to cause skin damage, including an increased risk of skin cancer. While the risk associated with UV nail lamps has been debated, with some studies suggesting that nail salon exposures are within safe limits, recent research has raised concerns. This new research indicates that long wavelengths of ultraviolet light (UVA) from UV nail dryers can damage DNA and increase the risk of skin cancer. Therefore, it is essential to follow safe practices and take precautions when using UV nail lamps.
To minimize the risks associated with UV nail curing, it is crucial to ensure proper curing. This involves considering factors such as the range of UV wavelengths, the intensity of the emitted wavelengths, the duration of UV exposure, and the thickness of the UV gel. Additionally, individuals with concerns about UV safety can use protective measures such as opaque gloves or a cloth over the hands during the drying process.

LED nail lamps as an alternative to UV light
Using your phone's flashlight to cure gel nails is not recommended. While some high-quality LED flashlights may emit the right wavelength to cure gel nail polish, most non-specialized LED flashlights and phones don't emit light with a wavelength below 400nm, which is typically required to cure gel nail polish.
LED nail lamps are a safer alternative to UV light for curing gel nails. While both LED and UV nail lamps can cure gel polish, UV light emits ultraviolet radiation, which can be harmful to your health. LED nail lamps, on the other hand, do not use any UV light and, therefore, pose no risk to your skin.
LED lamps emit narrower UV wavelengths with higher concentration and energy, which enables the gel to cure much faster than with UV lamps. LED lamps are also easier and more cost-effective to maintain, as they tend to last longer and use less energy than UV lamps. However, not all gel polishes can be cured by LED lamps, so it's important to check whether the brand of gel polish you are using is compatible with an LED lamp.
When choosing between an LED and UV nail lamp, consider your budget, the time you want to spend on curing your nails, and the products you use. LED lamps are typically more expensive than UV lamps but can save you time and provide a safer option for curing your gel nails.

The right wavelength of light to cure gel nails
Curing gel nails requires a specific wavelength of light, typically in the ultraviolet (UV) range. The specific wavelength needed depends on the gel polish being used. Most gel polishes require a wavelength of under 400 nanometres (nm) for curing, with some sources specifying 365 nm, 375 nm, 385 nm, 395 nm, or 405 nm as common wavelengths used by curing lamps.
It is important to note that not all LED lamps can cure every type of gel polish. Some polishes are designed specifically for UV lamps and will not work with an LED lamp. Therefore, it is essential to check the manufacturer's recommendations for the specific gel polish being used to ensure the correct curing method is applied.
The wavelength of light is not the only factor influencing the curing process. The intensity of the light, the exposure time, and the thickness of the gel polish layer also play crucial roles in achieving proper curing.
While some sources suggest that high-quality LED flashlights or phone flashlights may emit the required wavelength for curing gel nails, most non-specialised flashlights do not emit waves below 400 nm. Therefore, it is unlikely that a phone flashlight will be effective for curing gel nails.
To summarise, achieving the proper curing of gel nails requires using the correct wavelength of light, which is typically in the UV range, as well as considering other factors such as light intensity, exposure time, and polish thickness. Following the manufacturer's recommendations for the specific gel polish is essential to ensure effective and safe curing.

Using non-UV gel nail polish
It is not recommended to use your phone's flashlight to cure gel nails. Most non-specialized LED flashlights and phones don't emit waves below 400nm, which is typically required to cure gel nail polish.
If you want to avoid the potential health risks associated with curing gel nail polish using UV light, you can opt for non-UV gel nail polishes. These polishes are applied in the same way as regular nail polish and are designed to dry on their own without the need for a UV or LED light source. Some popular options include Sally Hansen's Miracle Gel line and Essie's Gel Couture line.
To speed up the drying process of non-UV gel nail polish, you can try the following methods:
- Using a quick-drying nail polish spray—hold the can about 7 inches (18 cm) away from your hand and spray a light coat over your wet nails.
- Using canola oil cooking spray—hold the spray about 6 inches (15 cm) away and spray each finger with oil while the polish is still wet. The oil will help the polish dry faster, but it will also leave your fingers feeling sticky, so be careful not to touch anything while your nails dry.
- Dipping your nails in ice-cold water to help the polish dry and harden faster.
- Using a four-step manicure kit like Dazzle Dry, which air-dries in five minutes without the need for a UV lamp.
Additionally, you can look for gel-like nail polishes that dry and cure without the need for UV light. These include polishes like Seche Vive, which has both monomer and activator, and HoloTaco, which offers a long-lasting base and top coat. When choosing a non-UV gel polish, be sure to read the instructions carefully to determine the best way to apply and dry the polish for optimal results.

Other ways to cure gel nails without a UV light
You cannot cure gel nails with your phone flashlight. Most non-specialized LED flashlights and phones don't emit waves below 400nm, which is typically required to cure gel nails.
If you don't have access to a UV light, you can opt for non-UV gel polishes that are made to dry on their own without light. These polishes take time to dry, just like regular nail polish. Here are some tips for curing gel nails without a UV light:
- Use a quick-drying nail polish spray. Hold your hand out on a flat surface covered with newspaper or paper towels. Hold the can of quick-drying nail polish spray about 6-7 inches (15-18 cm) away from your hand and spray a light coat over your nails while the polish is still wet. Repeat this process for the other hand, and then allow both hands to dry completely.
- Use canola oil cooking spray. Place some newspaper or paper towels on a flat surface and lay your hand out with your fingers spread apart. Hold the cooking spray about 6 inches (15 cm) away and spray each finger with oil while the polish is still wet. Repeat this for the other hand. The oil will dry in a few minutes, but it will leave your fingers feeling sticky, so be careful not to touch anything.
- Use an ice bath. Allow your nails to dry for 5-10 minutes after applying the last coat of gel, and then soak your nails in ice-cold water.
- Use thin coats of polish and wait 5 minutes between coats so that the polish dries completely before moving on to the next step.
- Use a clear gel polish that contains Keratin, such as Gelous Nail Gel, to strengthen, harden, and reinforce weak nails.
