почему вздувается гель лак Nails

It is quite difficult to do a manicure using gel polish at home, since the procedure involves adherence to a large number of subtleties that ladies often neglect, which affects the quality of the result.

With careless execution of decorative coating, sometimes ladies encounter the problem of the formation of defects, bubbles on the varnish. Why can gel polish swell associated with the poor quality of the applied composition or non-compliance with the pigment distribution instructions.

The main causes of gel polish swelling on nails

One of the common phenomena during the application of a decorative coating on natural nails is the appearance of air cavities on the solidified layer. Girls do not always know why gel polish is bubbling and how to get rid of such consequences.

Why does gel polish swell?

The reasons why nail polish bubbles after application are most often associated with non-observance of the features of the manicure technology.

Illiterate processing of the nails

At the beginning of the work, lady always needs to prepare the nail bed. To do this, first the shape of the free edge is corrected, the cuticle is removed, and then the uneven surface sanded with buff to remove natural irregularities.

With insufficient grinding of the plate, the varnish lays down unevenly, which is why air cavities appear, which form bubbles after drying.

Shaking bottle before use

It often happens that the lady does not use gel polish for several months, and then shakes it before applying to connect the separated layers. However, keep in mind that application often launches air into the composition, which is why it is transferred to the nail.

In this case, it is recommended to use an orange stick for mixing the composition.

Thick coating layer

Some ladies believe that in order to obtain a rich shade of varnish, the pigment should be applied in the maximum number of layers, despite the fact that a natural manicure overcoats after the second application.

With repeated use of the nail polish, the lower layers begin to soak, which leads to their swelling. As a result, the technique ends up with bubbles.

Application of nail polish from different manufacturers

Sometimes a woman chooses a base, and top from different manufacturers, focusing on her convenience in applying the compositions. However, components of different compositions can often conflict with each other, which leads to swelling of the coating some time after drying or the formation of microcracks on the surface.

Low wattage lamp application

In order for the applied coating to dry immediately, you should pay attention to the UV or LED lamp in which you plan to dry the coating. When drying work at low power, you will need a lot of time, during which the damp decorative coating begins to deteriorate – leaks, bubbles and other defects form.

Consider the minimum power rating of the device when buying it:

  • Ultraviolet – from 36 W;
  • LED – from 20 W.

Sometimes the low power of the device may be due to the fact that the internal bulbs burn out. Then replace them with new ones and keep using the device.

Low quality nail polish

Beforehand, you always need to pay attention to the quality of consumables and nail polishes that you use to apply to the nail plate, because when applying poor quality solutions can ruin the health of your manicure.

Sometimes problems arise due to the fact that the ladies forgets about the expiration date of the gel polish.

Despite the fact that it is stored for a long time, the effect of the polymers gradually deteriorates, which affects the general state of work.

Incorrect finger placement during drying

In the salon, the nail technician always warns customers to carefully put their fingers into the device and gives advice on how to do this in order to prevent the wet base from leaking to the side rollers.

Why does gel polish swell?

However, as a consequence of drying the gel polish at an angle, the formation of micro bubbles can also occur, because in the process of solidification, the composition gradually flows down, air enters its structure, due to which it solidifies in an inaccurate state. This factor most often occurs during drying thumbs, as you need to be as careful with them as possible.


The formation of air cavities and bubbles on a dried decorative coating is quite common among novice craftsmen, since there are many factors, which can lead to such consequences. If you follow the step-by-step instructions for performing the technology, you will ensure a positive result in the form of a neat manicure or pedicure.
