Nail extensions and gel manicures have become a popular beauty trend worldwide. From glossy finishes to long-lasting designs, they offer convenience and style. However, growing discussions around UV exposure during nail treatments have raised an important question: Can nail extensions increase the risk of skin cancer?
Let’s explore the facts in a balanced and evidence-based way.
How Nail Extensions Work
Many nail extension and gel polish procedures require curing under ultraviolet (UV) lamps. These lamps harden gel products to create a durable, chip-resistant finish.
There are typically two types of lamps used in salons:
- UV lamps
- LED lamps (which also emit UV radiation, but in a narrower range)
Both types emit ultraviolet radiation, similar in type (though much lower intensity) to that found in tanning beds.
Understanding UV Radiation and Skin Cancer
Ultraviolet radiation is known to damage skin cells over time. Prolonged or repeated exposure can increase the risk of developing skin cancers such as:
- Melanoma
- Basal cell carcinoma
- Squamous cell carcinoma
However, the level of UV exposure from nail lamps is significantly lower than tanning beds or direct sunlight.
What Does Research Say?
Current research suggests that the risk from occasional nail lamp use is relatively low. The exposure time during a typical manicure (usually a few minutes per session) is short.
That said:
- Frequent sessions over many years may increase cumulative UV exposure.
- People with fair skin or a history of skin cancer may need to be more cautious.
- Long-term effects are still being studied.
Most dermatologists agree that while the risk is not extremely high, it is not zero.
Are LED Lamps Safer?
LED lamps cure nails faster and may reduce exposure time. However, they still emit UV radiation. The difference lies mainly in wavelength and duration, not complete elimination of risk.
Shorter curing times may slightly reduce overall exposure.
How to Reduce Your Risk
If you enjoy nail extensions but want to minimize potential risks, consider these safety steps:
1. Apply Broad-Spectrum Sunscreen
Use SPF 30 or higher on your hands 15–20 minutes before UV exposure.
2. Wear UV-Protective Gloves
Special manicure gloves expose only the nails while covering the rest of the hand.
3. Limit Frequency
Avoid excessive back-to-back sessions if possible.
4. Choose Reputable Salons
Ensure proper equipment maintenance and hygiene standards.
Who Should Be Extra Careful?
- Individuals with a personal or family history of skin cancer
- People with very fair or sensitive skin
- Those frequently exposed to UV radiation in other settings
Consulting a dermatologist can help assess personal risk factors.
Final Verdict
So, can nail extensions increase the risk of skin cancer? The evidence suggests that occasional use poses a low risk, but repeated long-term exposure may contribute to cumulative UV damage.
While there is no need to panic, awareness and simple protective measures can significantly reduce potential risks.
Beauty and health can coexist — the key is making informed choices.
