1. The Gel Layers Are Too Thick:

  • This is the top reason for your gel polish not curing and is making you lose your patience.
  • When the gel layers are too thick, and you use the UV or LED lamp to cure them, the light does not penetrate the inner layers. Only the topmost layer is hardened, which gives the misconception that the gel polish is cured.
  • In most cases, this situation arises while using light-colored polish. Because then you need help understanding how much polish you have applied.


  • Always apply thinner layers to ensure that UV rays help in the complete curing process.
  • While using a light color, wipe the brush on the neck of the bottle to remove the excess polish. This is a great tip to follow and avoid the situation you hate.

2. The Nails Aren’t Prepared Properly

  • Well, this is the most ignored step by most people. The process of applying nail polish carries three essential steps.
  • Apply the base coat, the gel polish, and the top coat. All these steps need their recommended time to be cured after their application before moving on to the next step.
  • If you are in a hurry and avoid this step, your nails will appear messy and unfinished.


  • Make sure you give each layer its required time to be adequately cured, and then only move to the next step. Never be in haste.
  • When applying gel polishes, after the application of the top coat, non-acetone or alcohol is wiped on the nails to complete the process. This process must be followed as it seals the nail polish and cures it completely.

3. The Use of Wrong Lamp:

  • This issue needs your complete attention because this is something many people are unaware of. 
  • Every gel polish is cured with its specific light only. For example, if you have applied a UV gel polish and are curing it with LED light, it won’twon’t cure. A UV gel polish needs a UV lamp, the same as the LED gel polish.
  • Also, many brands cure only certain gel polishes and not others.


  • Before buying any lamp, make sure about the type of gel polish you are using.
  • Make sure to purchase the gel polish which is compatible with being cured by a specific lamp or not.

4. Base Coat or Top Coat Not Applied

  • This may seem like an unimportant step but it forms the basis of the manicure.
  • If you neglect this step, your gel polish won’t give a finished and satisfied look. It will not be cured.
  • If you apply the gel polish directly to your nail care, without the base coat, it will appear tacky and odd.
  • Similarly, a top coat is essential for sealing the nail polish and providing the desired look.


  • Always use the base and top coat to get your desired look.
  • If you need to remember any step by mistake, it is better to start the process again to avoid the consequences.

5. Curing Time is Too Short:

  • Curing time is also a significant point to keep in mind. All the gel polishes have varying curing times.
  • Sometimes over-curing results in some consequences like the loss of brightness and discoloration, or it will crack and flake faster than you may think.


  • Curing time is critical to look at while you are applying gel polishes.
  • Cut the polishes as required, or else it will lead to over-curing or under curing.

The Correct Way of Curing Gel Polish:

When applying gel polish, keep in mind some of the tips to ensure properly cured nails.

  • ALWAYS APPLY THINNER COAT: A thinner coat is necessary to ensure proper UV light absorption in each nail polish layer. Thicker coats do not allow the UV light to penetrate the nails, and the gel polish remains uncured.
  • CHANGING OF BULBS OR LAMPS: UV lamps need changing every 4 to 6 months, depending upon how frequently you are using them. Sometimes due to a busy schedule, lamp or bulb changing cannot happen, and this affects the curing process. Also, remember to keep the bulbs clean to ensure the right intensity of light passes through.
  • USE OF A CORRECT LAMP: Well, there is no correct way to recognize which brand lamp cures which brand gel polish. Sometimes, a simple lamp can cure a branded gel polish, and sometimes it becomes a problem. So, it can be only advised to check whether or not the lamp and gel polish are compatible.
  • CHECK FOR UNDER CURING: The best way to identify under-curing is to check whether bubbles appear on the nail surface. This indicates that the gel polish does not adhere properly and may come off. Other situations may be a cloudy finish, soft surface, or areas where the color may disappear.
