Gel nail polish is cured and hardened using a UV or LED lamp. The process, known as polymerisation, causes the molecules in the gel polish to bond together, creating a solid layer of colour that is resistant to chipping and damage. The curing time varies depending on the type of lamp and nail, but it typically ranges from a few seconds to several minutes. It is important to note that gel polish is light-sensitive and will react to sunlight or natural light if exposed for an extended period. Therefore, it should be stored in a dark place and at room temperature. Additionally, the lamp must be placed at an appropriate distance from the nails, usually around 2 inches, to ensure the gel base coat and top coat form correctly.

What You'll Learn

Gel nail curing process
Curing gel nail polish involves using a specially designed UV or LED lamp to seal and harden the gel nail polish on your nails. This process is known as polymerisation, which causes the molecules in the gel polish to bond together, forming a solid layer of colour that won't easily chip or wear off.
The curing time can vary depending on your nail type and the type of lamp used, ranging from a few seconds to several minutes. It is important to cure each gel layer completely before proceeding to the next. To achieve a perfect manicure, it is recommended to paint and cure each hand or finger separately, which helps to avoid smudging. The base gel coat should only be exposed to the LED lamp for 45 seconds to avoid over-curing, which can result in decreased adhesion and brittleness. The gel polish colour coat should be properly cured to preserve its flexibility. The topcoat should be cured for a maximum of 90 seconds.
To test if your gel is curing properly, you can take a bead of gel and apply it to a form, cure it for one minute, and then check the underside of the gel. If the underside is still liquid, the gel has not cured properly. It is also important to note that the LED lamp bulb must be powerful enough to emit UV light at the correct frequency.
After curing, a sticky residue may be produced, which can be removed using a cotton pad soaked in alcohol or a specialised gel cleanser. This step ensures that your nails are left feeling smooth and flawless.

LED lamp placement
The placement of an LED lamp is critical to the success of the curing process. The lamp must be positioned at the correct distance from the nails to ensure effective curing and avoid over-curing. The recommended distance between the LED lamp and the nails is approximately 2 inches. This allows for the optimal amount of UV light to reach the gel polish, facilitating the polymerisation process and resulting in a solid, chip-resistant manicure.
The wattage of the LED lamp is another important factor to consider. Higher-wattage bulbs emit more curing energy, leading to faster curing times. Most professional LED nail lamps have a wattage of at least 36 watts, with some sources recommending a minimum of 48 watts for optimal performance. The higher wattage also ensures that the gel polish receives the necessary level of UV radiation for curing.
When choosing an LED lamp, it is essential to consider the type of gel polish being used. Not all gel polishes are compatible with LED lamps, as some are specifically designed for UV lamps. Therefore, it is crucial to follow the recommendations provided by the gel manufacturer to ensure the proper curing of their product. Additionally, the type of LED bulbs within the lamp and their placement can vary, impacting the overall effectiveness of the curing process.
The curing time for each layer of gel polish should be carefully followed to avoid over-curing or under-curing. The base coat, for instance, should only be exposed to the LED lamp for 45 seconds, while the top coat should be cured for a maximum of 90 seconds. The top coat requires more curing time to preserve the colour and provide a luminous finish. However, excessive curing of the top coat can make it hard and solid, requiring manual filing for removal.
LED lamps offer several advantages, including faster curing times compared to UV lamps. They also tend to last longer, as UV lamps often require frequent bulb replacements. The brightness of LED nail lamps is an indicator of their high wattage, which is necessary to provide the required level of UV radiation for curing gel polish. Overall, the placement and specifications of the LED lamp play a crucial role in achieving the desired curing results for gel nails.

Gel polish storage
To cure gel nail polish, you need to use a UV or LED lamp. This process, known as polymerisation, causes the molecules in the gel polish to bond together, creating a solid layer of colour that is resistant to chipping.
Now, onto gel polish storage. It is important to store your gel nail polishes correctly to ensure their longevity and maintain their quality. Here are some tips and guidelines for storing your gel polishes:
Storage Location:
- Store your gel polishes in a cool, dry place away from direct sunlight. Sunlight can cause the polishes to heat up and may affect their formula.
- Avoid storing them in extremely cold places as well, as this can cause the polish to thicken or separate.
- The ideal storage location is a temperature-controlled area, such as a room-temperature cabinet or drawer.
Storage Container:
- Use a dedicated nail polish storage case or organiser to keep your gel polishes in one place.
- Look for a case with compartments or dividers to keep each bottle upright and secure.
- Ensure the storage case has a secure closure to prevent accidental spills.
- Consider a portable storage case if you're a nail technician or if you want to easily transport your gel polishes when travelling.
Bottle Care:
- Keep the bottles upright and handle them with care to avoid spills or leaks.
- Wipe off any excess polish from the bottle's neck and brush after each use to prevent the polish from drying out or clogging the brush.
- Ensure the caps are tightened securely after each use to maintain the polish's freshness and prevent evaporation.
Expiration Dates and Consistency:
- Gel polishes have a longer shelf life compared to regular nail polishes, but they can still expire. Pay attention to the expiration dates and discard any polishes that have passed their prime.
- Over time, the formula may thicken or separate. Gently roll the bottles between your palms before each use to reincorporate the ingredients and maintain a smooth consistency.
Organising Your Collection:
- If you have a large collection of gel polishes, consider organising them by colour, finish, or brand to easily find the shade you're looking for.
- You can also group them by season or create custom categories based on your preferences.
- Use labels or a colour-coding system to easily identify each polish, especially if they are stored in a drawer or cabinet.
Additional Tools and Accessories:
- Store your UV/LED lamp, cleanser wipes, cuticle pushers, and other tools and accessories needed for the gel polish application and removal process together with your polishes.
- Ensure you have all the necessary items organised and readily available to simplify the manicure process.
By following these guidelines, you can effectively store your gel polishes, maintain their quality, and ensure they last for many manicures to come.

Gel polish application
Gel polish is a popular product that can be applied at home or in a salon. It is a gel-like formula that is applied to the nails and then hardened using ultraviolet light, or a UV or LED lamp. The process of hardening gel polish is called curing and it causes the molecules in the gel polish to bond together, forming a solid layer of colour that is long-lasting and chip-resistant.
Applying gel polish is an art and a science. Here is a step-by-step guide on how to apply gel polish:
- Nail Preparation: Before applying gel polish, it is important to prepare the nails. This includes pushing back the cuticles, which makes the nail bed larger and provides a bigger canvas to paint on. Buff the nail plate to remove any remaining dead skin and ensure that the nail is free of any natural oils or shine, as this can act as a barrier between the nail and the polish.
- Primer Application: Apply a primer to enhance the adhesion of the nail plate with the gel polish. There are two types of primers: acid primer and acid-free primer. Place 1-2 small dots of primer on the nail and allow it to spread and evaporate completely.
- Base Coat Application: Apply a thin layer of gel base coat to the nails, being careful not to get it on the cuticles. Cure the base coat under a UV or LED lamp for 45 seconds.
- Colour Coat Application: Apply a thin layer of colour gel polish, painting over the tip of the nail. Cure for 30 seconds under the lamp. Repeat this step for two to three coats, depending on the desired pigmentation.
- Top Coat Application: Apply a gel top coat, again painting over the tip of the nail. Cure the top coat for a maximum of 90 seconds. The top coat protects the colour underneath and gives the nails a luminous finish.
- Wipe Off Inhibition Layer: After curing the top coat, wipe off the inhibition layer with a lint-free wipe and rubbing alcohol. This layer is sticky and helps the coats adhere to each other, but it needs to be removed for the final top coat to adhere properly.
- Final Top Coat Application: Apply a final top coat to protect the colour and increase the longevity of the manicure.
- Aftercare: Avoid direct contact with water for at least an hour after application. Use cuticle oil regularly to keep your nails hydrated and always wear gloves when washing dishes or cleaning.

Gel polish removal
Gel nail polish is cured using a specially designed UV or LED lamp. This process, known as polymerisation, causes the molecules in the gel polish to bond together, forming a solid layer of colour that won't chip or wear off easily.
To remove gel nail polish at home without damaging your nails, follow these steps:
- Prepare a bowl filled with acetone and soak ten cotton wool balls until they are saturated.
- Apply a thin layer of petroleum jelly to the skin around your nails and cuticles to protect them during the removal process. You can use cuticle oil or Vaseline.
- Place each acetone-soaked cotton wool ball onto your nails and wrap your fingertips in foil to hold it in place.
- Set a timer and leave the foil on for 10-15 minutes.
- Lightly massage the foil and pull it away from your nail.
- When the gel has lifted, gently remove any excess polish with an orangewood stick, going from cuticle to tip.
- Wash your hands with gentle, fragrance-free soap and water to remove the acetone.
- Apply a moisturising hand cream and nourish your cuticles with cuticle oil.
Alternatively, you can use plastic food wrap instead of foil. This creates a tighter seal, so the acetone is less likely to drip.
You can also try the double-boiler method, where you use a special bowl with a removable bottom filled with hot water to warm the acetone.
It's important to note that you should never pick or file off gel nail polish, as this can damage your nails and cause white spots.
