Can You Use Any Lamp for Shellac? Understanding UV Requirements

Understanding Shellac Nails

Shellac is a hybrid product that combines the durability of gel nails with the ease of application of regular nail polish. When you opt for a shellac manicure, your nail technician will follow a specific process to ensure the longevity and shine of your shellac nails.


  • Your nails are first cleaned and shaped.
  • The cuticles are pushed back to ensure a clean nail plate for the application.


  • A base coat is applied to protect your nails and help the color coat adhere better.
  • After the base, the color coat of your choice is precisely applied. Shellac comes in a vast array of colors, enabling you to pick the perfect shade that matches your style or occasion.
  • It’s important to note that CND Shellac is specifically formulated to work seamlessly with the CND UV or LED lamps for curing.


  • Between each coat, your nails are cured under a UV or LED lamp, which hardens the product for a durable finish.
  • CND recommends using its brand of lamps to guarantee the manicure’s longevity typically advertised as 14 days without chipping.

Final Touches:

  • A top coat is then applied to give your nails a glossy finish and additional protection.
  • Once the top coat is cured, you have a resilient, chip-free manicure.

By adhering to the standardized protocol and using recommended products like CND’s lamps and polishes, you achieve the full benefits of shellac nails without compromising on quality.

Types of Lamps for Curing Shellac

When choosing a lamp for curing Shellac, it’s essential to select one that is compatible with the product to ensure optimal performance and lasting results. Consider the wattage, wavelengths, and type of lamp to match your needs.

UV Lamps

UV lamps have been traditionally used for curing Shellac and other gel polishes. UV Lamps typically emit a broad spectrum of ultraviolet light and require a longer curing time. They are compatible with most types of gel polish, but they operate at a lower wattage, which means your manicure might take longer to set. UV lamps are known for their consistent UV output over time, which can be important for professional salon use.

LED Lamps

In contrast, LED Lamps emit a narrower range of wavelengths but do so with greater efficiency. LED lamps have a higher wattage and cure Shellac much faster compared to UV lamps, often in 30 seconds to a minute. LED lamps are generally bulb-free and are designed for a specific wavelength of light, around 405 nanometers, which is optimal for curing some gel polishes.

Comparing UV and LED Lamps

When comparing UV and LED Lamps, consider the following:

  • Wavelengths: LED nail lamps operate at specific wavelengths suitable for curing Shellac quickly, while UV lamps emit a broader spectrum that may take longer but works with a wide variety of gels.
  • Wattage: LED lamps tend to have a higher wattage, which means Shellac may cure more efficiently.
  • Performance and Duration: LED nail lamps offer a faster curing time and typically last longer without the need for bulb changes, whereas UV lamps provide a steady and consistent performance over a more extended period.

It’s crucial to ensure that the lamp you choose is specifically designed for the type of Shellac you are using to guarantee the advertised duration and quality of your manicure.

Shellac Curing Process

When applying Shellac nail polish, curing is an essential step. This process requires exposing the Shellac to a specific type of light to harden or set the polish properly on your nails. Here, we’re outlining the aspects of curing your Shellac nail polish correctly.

Types of Lamps: The manufacturer recommends curing Shellac with CND lamps. These lamps are designed to emit UV or LED light at optimal wavelengths and intensities to facilitate the proper cure for Shellac products.

  • UV Lamps: Traditional lamps for curing Shellac, taking a bit longer for the polish to set.
  • LED Lamps: Offer faster curing times and are more energy-efficient than UV lamps.

Manufacturer’s Instructions: It’s best to follow the manufacturer’s instructions for the specific lamp you’re using. CND Shellac is formulated to work with their CND lamps to ensure a quality manicure that should last up to 14 days without chipping.

  • Curing Time: Usually, it takes about 30 seconds to two minutes under an LED lamp and slightly longer under a UV lamp.
  • Wavelength: Ensuring the wavelength matches what’s required for Shellac is crucial, as not all lamps emit the correct range.

Compatibility: While some users may find that other high-quality curing lamps can set Shellac, this is not guaranteed. Using a specific lamp recommended by the brand ensures your Shellac cures as it is intended to.

By adhering closely to these curing guidelines, including using the right curing lamp and following the manufacturer’s instructions, you can achieve a salon-quality Shellac manicure at home.

Benefits and Risks of Shellac Manicures

When considering a Shellac manicure, you should weigh both the aesthetic benefits and the potential health risks to make an informed decision.

Advantages of Shellac

Long-lasting wear: One of the primary advantages of a Shellac manicure is its durability. Shellac is a blend of gel and nail polish that, when cured under UV or LED lighting, can last up to two weeks without chipping or peeling. This longevity means your nails maintain a high gloss and flawless appearance for longer than traditional nail polish.

No waiting for nails to dry: Unlike regular nail polish, Shellac dries almost instantly under the curing lamp. This means you can carry on with your day immediately after the manicure without worrying about smudging or ruining your polish.

Potential Risks and Precautions

Exposure to UV light: Curing Shellac requires exposure to UV light, which can pose risks to skin health. While the curing process is generally considered safe, repeated and prolonged exposure could potentially increase the risk of skin aging and skin cancer. It’s recommended to apply sunscreen to your hands or use protective gloves that only expose your nails to minimize these risks.

Chemical Sensitivity and Nail Damage: The removal process for Shellac manicures often requires soaking the nails in acetone, which can be drying and may cause irritation to the cuticle and surrounding skin. Regular use of Shellac can also lead to nail brittleness, thinning, and cracking if precautions — such as regular breaks between applications and making sure to moisturize the nails — are not taken.

Not all lamps are insured for use with Shellac: It’s important to note that while Shellac can be cured in both UV and LED lamps, the brand that distributes Shellac only guarantees its product when used with their own lamps. Using other lamps might not cure the polish correctly, which can affect the manicure’s longevity and possibly lead to under-cured polish that could peel off prematurely.

In conclusion, while Shellac manicures offer a long-lasting, glossy finish with a quick curing time, you should take the potential skin and nail risks into account. It’s crucial to follow safety guidelines, such as using the appropriate lamp and taking breaks between applications, to ensure your manicure remains both beautiful and healthy.

Choosing the Right Lamp for Shellac

When you’re seeking to perfect your Shellac manicure, selecting the proper lamp is not just an option but a necessity. LED lamps are specifically designed to cure Shellac polish efficiently and are favored due to their faster curing times.

  • Professional Use: If you’re a professional, investing in a CND’s UV or LED lamp is recommended, as they are precisely calibrated for optimal curing of Shellac polishes.
  • Home Use: For personal use, a generic LED lamp may serve your needs, provided it’s of good quality. Do verify that the lamp is LED curable, as not all lamps will properly cure Shellac.

A detailed comparison of lamp types:

Lamp Type Compatibility Quality Investment
CND Branded Lamps High Professional Higher
Generic LED Lamps Moderate Good Moderate
Non-LED Lamps Low Variable Lower

Bear in mind that using a generic lamp could result in a manicure that is less than optimal. Your investment in a high-quality, LED or UV lamp will ensure not only the longevity of your manicure but also that the finish and durability align with the standards Shellac is known for.

Remember, a proper lamp doesn’t only harden the polish; it also brings out the color’s true depth and shine. Choose wisely to maintain the integrity and beauty of your Shellac manicure.

Shellac Application and Maintenance

When applying Shellac nail polish, meticulous preparation and proper maintenance ensure the longevity and beauty of your manicure. Here’s how you can master both application and upkeep for a professional-looking Shellac finish.

Preparation for Application

Before applying your Shellac nail polish, prepare your nails to ensure the best adhesion. You’ll need a nail file to shape your nails and a buffing block to create a smooth surface. Cleanse your nails with an acetone-based polish remover to remove any oils or residue. It’s important to push back the cuticles and use a cuticle oil that you should then cleanse off thoroughly. Ensure your nails are completely dry and free of dust.

Applying Shellac Nail Polish

Choose your color of choice and begin the application process:

  1. Apply one coat of Shellac base gel and cure it under a UV or LED lamp, as specified by the polish instructions.
  2. Follow with two thin coats of the Shellac gel polish, curing after each. Make sure you cover the nail edges to seal in the color.
  3. Finish with a topcoat and cure for the final time to secure the manicure.

Remember, the lamp you use does impact the quality of your Shellac manicure. While Shellac is designed to cure with CND’s specific lamps, using other UV or LED lamps may not guarantee the same 14-day duration of the manicure or ideal cure.

Maintaining Shellac Nails

For a long-lasting manicure, maintenance is key:

  • Avoid prolonged exposure to water and wear gloves when cleaning.
  • Moisturize your hands regularly and use cuticle oil to keep your nails healthy.
  • Do not pick or pull at the polish. If you wish to remove it, use a Shellac-specific or acetone-based remover and gently soak the nails.

By adhering to these steps, you’ll help ensure your Shellac manicure remains splendid for weeks.

Alternatives to CND Lamps and Products

When seeking alternatives to CND lamps for curing your Shellac or other gel polishes, consider both UV and LED lamps. UV lamps have been the traditional choice and can cure most types of gel nail polishes. These lamps typically require more time for the curing process—usually around two minutes.

LED lamps, such as the Nail Harmony 9G LED lamp, offer quicker curing times, generally curing gel polish within 30 seconds to a minute. LED lamps have a narrower spectrum of UV light but are often preferred for their speed and energy efficiency.

When selecting a nail lamp, confirm that it’s compatible with the type of gel polish you’re using. Here’s a simple comparison:

Nail Lamp Type Curing Time Bulb Life Expectancy
UV Lamp ~2 minutes 1,000-2,000 hours
LED Lamp 30-60 seconds Up to 50,000 hours

For a hybrid option, there are versatile lamps available which can cure both types of gel nail polishes. By providing a wider range of wavelengths, these lamps are designed to accommodate the curing needs of various gel products.

Remember, not all gel nail polish brands will cure effectively with any lamp, so it’s essential to read the manufacturer’s instructions for your specific polish. While CND specifically formulates their lamps and polishes to work in tandem for optimal results and longer wear, you may find compatible lamps that also offer satisfactory results for Shellac and other gel nail systems.

Shellac Removal Process

To safely remove Shellac from your nails, it’s essential that you follow a specific process. This ensures that your nails stay healthy and avoids any unnecessary damage.

Step 1: Prepare Your Tools

Assemble the following items:

  • Cotton pads
  • Aluminum foil
  • Acetone polish remover
  • A nail file
  • A cuticle oil (optional but recommended)
  • Manicure sticks or an orange stick

Step 2: File the Nails

Take a fine-grit nail file and gently buff the surface of your shellac nails. You’re aiming just to break the seal of the top coat, rather than filing the polish off completely.

Step 3: Apply Acetone

Soak the cotton pads in acetone polish remover, placing one on each nail. Then, wrap your fingers with pieces of aluminum foil to secure the pads. It’s especially important to meticulously wrap the thumbs, as they tend to take longer to soak due to their size.

Step 4: Wait

Allow approximately 10-15 minutes for the shellac to soften. Keep an eye on the time—too short could make the polish harder to remove, too long could dehydrate your skin and nails.

Step 5: Remove the Covering

Twist and pull off the aluminum foil and cotton. If necessary, use the manicure stick to gently help lift any remaining polish.

Step 6: Moisturize

Post-removal, nails may feel dry. Apply cuticle oil to rehydrate and protect your nails.

If you’ve used a lamp other than the FDS shellac lamp, or a Gelish lamp, be aware that removal times can vary as these products might cure differently.

Remember, patience and care during the removal process are key to preserving the integrity of your nails.
