– Single-phase gel: what is it?

The monophasic gel is one of the main elements used in manicure and nail art. Technically, it can be considered as a polish with a slightly different composition, which guarantees a longer duration.

To ensure correct application and long life, however, it needs to be treated, ie heated in the light of ultra-violet ray lamps. Because of the need to use a heating source capable of fixing it to the nail, the monophasic gel is also called, although more rarely, photo-hardening gel.

The practicality of the gel is that it can be used in different contexts, that is both on nails in the natural state, untreated and on nails on which the reconstruction has been carried out.

However, as we will see later, in order to proceed with a correct application it is necessary to have a series of specific tools for the application and the heating of the gel itself.

It must be remembered that the monophasic gel, although much simpler and quicker to use than the bi-phasic and tri-phasic one, must however be applied with the utmost care, waiting for the time required for correct polymerization and, as will be seen later, paying attention to the use of the right lamp for a correct and long lasting fixing.

Monophasic, biphasic and triphasic

The practicality of using the mono-phasic gel is to be sought above all in the greater speed of application which, in turn, is allowed by the structure of the gel itself.

This product, in fact, being characterized by a single phase, needs only one and only application to obtain the final result.

The difference with the other types of gel for nails, respectively the bi-phasic and the tri-phasic, is therefore quite evident precisely because the mono-phase requires less application time being characterized by a single compound.

Conversely, the bi- and the tri-phasic require two and three products respectively. It should also be emphasized that, unlike the monophasic, the other two types of gel are mostly used for the actual reconstruction of the nails.

Later on, the difference in application of the different types of gel will also be illustrated quickly, depending on whether we need to proceed with a reconstruction or simply proceed with the application of the nail art polish.

Why choose the monophasic gel

Considering that there are different types of gels on the market that have the same functions, it may be natural to ask why a single-phase product should be chosen with respect to the three-phase one.

The answer, as you can imagine, is very simple: the monophasic one is much easier to apply and, therefore, more suitable for those who like to make their own manicure.

In fact, the monophasic gels foresee the application of a single element on the nail, which can vary in color or density but which is able to ensure a perfect result. In the application of the mono-phase gel it is important to remember that saving time is one of the elements that has made this type of gel so appreciated.

However, it must be specified that only when you are really expert in the use of this product will it actually be possible to save time in the drafting and application with the right technique.

How to evaluate product quality

Among the numerous types of single-phase gels it is essential to pay attention above all to the quality of the product: choosing the monophasic gel does not mean aiming for a product of poor quality.

For this reason, before purchasing it is necessary to evaluate not only the quality of the product through the technical sheet but also the reviews and comments of those who have already used it.

This last aspect is fundamental when working with this type of product: on the one hand, in fact the technical qualities, ie the composition and density, can be reported among the technical information of the product, while the actual result that can be obtained in the different techniques and applications it can be known only through tests.

For this reason, reading the reviews left online will ensure that a certain product is actually suitable for the different techniques, applications and needs. In this way you will not risk finding yourself with a product that is completely different from what was expected.

– How to use

It has already been mentioned that in order to use the monophasic gel it is necessary to have a specific ultra-violet lamp, which guarantees the perfect hardening of the gel for a longer duration over time. Below, we will explain the different steps necessary for a correct application of this nail product.

It should be remembered that, as with all aesthetic products, there are many different types of monophasic gels on the market: if the application and use methods are practically identical for all mono-phasic gels, the results may however be different depending on the brand and the quality of the gel itself.

What is needed for the application of the single-phase gel

In order to correctly apply the single-phase gel on the nails, not only the gel and the hardening lamp can be used.

Instead, you need to have everything you need for nail preparation on hand: the first few times, you may need to buy a monophasic gel kit so that you have all the tools and products you need for a perfect gel application. and making the manicure.

Below, therefore, will be listed the products needed to be able to best use the single-phase gel on a natural nail. Therefore, you will need to have:

  • single-phase gel of the brand and of the preferred density;
  • Ultra-violet lamp with specific wattage;
  • nail primer;
  • solvent;
  • orange wood stick and file;
  • cotton wool;
  • enamel (or better glazes);
  • cleaner.

Proper preparation of the nail is essential to be able to work on a clean, smooth nail without any irregularities which could then damage the perfect final result.

Any remaining nail polish from a previous manicure should be eliminated, as should cuticules and any cuticle should be removed. The nail should therefore be cleaned to perfection to ensure perfect adherence of the gel.

The application of the monophasic gel

As already highlighted, before applying the gel it is necessary to prepare the nails, cleaning them from any remaining glaze coming from a previous manicure.

Before applying the gel, it is advisable to use a primer to spread on the nails. To ensure a correct drying of the primer it is possible to insert the hands in the ultra-violet catalyst in order to speed up the drying process itself and ensure greater drying homogenization.

The gel should be applied just like a glaze, taking care to vary the amount to be spread, depending on the density of the gel itself. To be sure of a precise job, you can opt for a self-leveling monophasic gel that ensures maximum homogeneity in the drafting.

When the first coat is ready, it will be placed under the lamp to proceed with drying. Depending on the type of lamp, whether it is ultra-violet or LED, the time required for drying will vary between two minutes to about thirty seconds.

When the gel is dry you can move on to applying the enamel, in all the colors and decorations you want. Once all the enamel is dry you can proceed with a further application of the monophasic gel: in this way it will be possible to guarantee the nails a greater shine and a longer duration over time.

The best single-phase gels, if applied correctly, respecting all the drying times, last four weeks.

What the experts suggest

If you are not practicing the application of the monophasic gel because you are at the first experience it is essential to follow some tutorials that allow you to learn not only the application methods but also some tricks to improve the drafting and get a more brilliant and lasting result.

Some, for example, suggest to make a first very light draft of gel just as one does in the case of laying the base. This first pass can also not be catalyzed but it is necessary to make sure that it is perfectly dry before proceeding to the next step, that is to say the realization of the actual structure.

This will, of course, be filed and cured using the specific gel lamp used.

Finally, it is important to remember that the monophasic gel is perfect for making fast manicures and certainly many monophasic gels are better than three-phase products of dubious origin and production.

With equal quality products, however, it is essential to remember that even if the final result of a manicure made with two different gels can be comparable, the tightness, strength and resistance of the single-phase gel is always lower than that of a tri product. -phase.

This aspect must be taken into consideration for a correct evaluation of the product purchased.

– The importance of the lamp

When using the monophasic gel it is essential to use a lamp for heating the gel itself for better adhesion. In most of the guides for the use of the single-phase gel we will talk about ultra-violet lamps for the hardening (or better for the catalysis) of the gel itself.

However, when buying the gel, it is essential to make sure it is a uv gel, ie for use with ultra-violet lamps.

On the market, in fact, there are also LED gels. The difference in technology for the two lamps is also reflected in the composition of the gel: the gels that harden with ultra-violet lamps and those that catalyze with LED lamps are different.

This point is essential because we often think we can use the two lamps indifferently. This is a mistake since, as highlighted, the gels have different compositions.

Therefore we must not think of using an LED lamp in the case of gel created by catalyzing using ultra-violet and vice versa.

The only possibility that you have of using one or the other lamp is that the gel is made specifically to be used with both. In this case it will be possible to evaluate, depending on the time available or, above all, on what type of lamp is available, how to catalyze the gel.

The choice of lamp and gel

To understand the correct functioning of the lamps and why the different types of gels need different types of lamps it is necessary to know that the monophasic gels are made with polymers that react differently to heat. Some gels, in fact, catalyze correctly even when subjected to direct sunlight.

The ultra-violet radiations, in fact thanks to the specific frequency, give rise to chemical reactions that lead to a transformation of the gel that solidifies by binding in a very well structured way, guaranteeing a high resistance and solidity of the gel.

From the final result it is not possible to recognize if the gel used is of uv or led type: this means that the preference in the application of one or the other type is often exclusively subjective.

Often, we also talk about saving time in the use of gel for LED lamps, however it is worth noting that over the entire reconstruction or manicure, the total time that can be saved is very limited, being just a few minutes on operations that sometimes last even several hours.

Instead, what must be considered is cost savings: ultra-violet lamps, in fact, last much less than LED ones and therefore require more frequent bulb changes than LEDs.

Those who make frequent use of these lamps, therefore, may find it more convenient to opt for models that, in the long run, allow greater cost savings.

– Gel nails and single-phase gel reconstruction: what are the differences?

When talking about nail gel, be careful not to confuse all the different types of products that are used in the different operations necessary to ensure proper nail health and beauty.

For example it is important to know how to recognize the products for the reconstruction of nails and how and when these should be used.

The monophasic gel, for example, is not necessarily a product for reconstruction but can be used safely on the natural nail, after a simple application of the primer to ensure greater protection to the nail itself.

The different types of gel for reconstruction

It is not easy to disentangle in the world of reconstruction gels: in fact, they are truly many and differ in types, chemical characteristics, quality, durability and, of course, price.

Unlike monophasic gels, the reconstruction products are not so simple to use and a good mastery of both the reconstruction techniques and the types of gel is required.

These, in fact, by changing the composition, also change the density and viscosity which, in turn, influence the technique to be used for the reconstruction itself.

Reconstruction gels must not be purchased without having a good knowledge of the problem and how to solve it.

In fact, you can’t think of buying a gel and then using it on all types of nails to be rebuilt: vice versa, depending on the type of operation you will have to perform, you will need to choose a type of gel with chemical and technical characteristics suitable for the realization of that particular technique that must be used to obtain a good final result.

Not only reconstruction: base gels, polishes and sealants

The knowledge of different types of nail gel allows you to achieve perfect manicures and equally durable nail art operations.

For this reason, when making a reconstruction or when working on a natural nail, it is essential to know the different types of gels that can be used and, above all, to have a perfect awareness of when it is better to use one type and when another.

Therefore, it is good to know that beyond the specific products for reconstruction there are gels that are used above all to improve color retention, or to ensure a more accentuated aesthetic effect in certain contexts.

The basic gels, for example, whether they are more or less fluid, are successfully used before proceeding with the French manicure.

The polishing gels, as can be understood from the name, allow to refine the manicure guaranteeing a shiny or opalescent effect depending on the type of gel. Finally, the sealing gels also combine an important polishing effect to seal the reconstructed nail, thus ensuring greater durability and resistance to the same.

– Advantages and disadvantages of single-phase gel

When you decide to use the single-phase gel, it is often done thinking about its practicality, that is to the fact that it allows, with a single product, to obtain an ideal result for the nails both in the case of natural and reconstructed nails.

However, it should be noted that this type of product is not perfect and has some disadvantages. Below, we will briefly describe the pros and cons of this type of product.

Single-phase gel: the pros

As already pointed out, the practicality of use is certainly the main advantage of single-phase gels. However it is not the only one. First of all it is necessary to underline the economic saving that is obtained using this type of product.

Finally, even the saving of time for the drafting of a single product instead of three, as is the case for the tri-phasic one, although minimal compared to the total realization of the manicure, is certainly an aspect to be taken into consideration.

Another interesting aspect is that related to the possibility of choosing different gel densities depending on the type of use to be made of them.

The negative aspects of the single-phase gel

Although much appreciated by those who use nail products, it should be emphasized that monophasic gels also have some negative aspects, especially when compared to actual reconstruction products.

For example, with regard to resistance over time, single-phase do not exceed four weeks. Of course, if you use the gel for a simple nail art this time is more than enough but instead as regards the reconstruction operations it is instead an inadequate time.

An aspect that must necessarily be inserted both among the positive and negative aspects is that relating to density. In fact, this can be used incorrectly and give rise to inappropriate results.

For this reason, it is essential to learn to carefully choose the density of the gel since the liquid ones will have to be processed very quickly to avoid risking unsightly sagging and, above all, the main cause of nail detachment.

Single products or kits?

In choosing the gel, moreover, it is necessary to evaluate, depending on specific needs, whether it may be necessary to buy only the gel or an entire kit, which also includes all the tools necessary for a complete manicure.

When you do not have any type of product, that is, you do not have the tools for different operations such as nail preparation or micro nail art, you can choose a complete kit, made not only from the monophasic gal. The kits can be different from each other depending on the brand or line of products you use.


In choosing the monophasic gel it is important to evaluate a series of characteristics both of the gel itself and of the type of intervention that must be performed.

Specifically, if when used on natural nails, that is not for a real reconstruction but only to improve the nail art procedure, it is essential to choose a low or medium density gel while, in case of use for reconstruction, the density goes evaluated based on the type of intervention to be performed.

Those who do not have a good knowledge of the nail gel market will find it difficult to choose due to the very high number of products present, some of excellent quality, others of a slightly lower level but still very good.

Of course, it is essential to stay away from poor monophasic gels that could not only compromise the work from an aesthetic point of view, but also create health problems on the nail itself.
