In the following, you can read what the various criteria consist of and learn why it makes sense to acquire a nail hardener in aspects or not.

Formaldehyde content

We have already pointed out the dangers of this active ingredient in the decision segment, where the different forms of nail hardener are registered. You will get a description detailed from the dangers below, where you’ll find some interesting facts about nails and nail hardeners.

If you tend to have sensitive skin, then the product could deploy its potential side effects in one application. Note that if the fixture hardens your nails, it can dry out and irritate your cuticles and nails at the same time.

If the effects of such use are too risky for you, you should avoid products containing formaldehyde. Some nail hardener manufacturers deliberately avoid the controversial active ingredient and use alternative nutrients for their products.


As a result, a bottle may contain less or more than1 milliliters. This is relevant to knowing how much you are willing to pay for what amount.

The cost of purchasing nail products varies. In particular because of the amount of liquid with which the manufacturer fills the bottles. But some products with less content are more expensive than nail hardeners with more content.

So you have to choose if you want to choose a certain supplier or if the supplier plays a minor role for you. Some manufacturers offer fairly small bottles, but offset by a quick and lasting effect.

You have to choose between a fast and effective nail hardener with very little content and a nail hardener that you can use for a longer period of time, but which can just work after a longer period of use.


Most nail hardeners are fairly easy to spot. However, a distinction is made between fully transparent varnishes and varnishes that give off a light shade.

Colored products are generally available in shades naked, beige and pink. Thus, the nails also seem maintained and catch the eye. There are also colored varnishes that completely cover the nail, which should harden the nail further.

If you want to use the best nail hardener as a base coat and then want to varnish your nails with a color varnish of your choice, we recommend a nail hardener that leaves a clear conclusion. Otherwise, the end result would become discolored. The same goes if you want to use the nail hardener as a top coat.


Many girls like their nails to shine beautifully. But there are also people who don’t like their nails attracting the attention of others. Matt varnishes are therefore suitable for men or people dissatisfied with their nails.

There are different offers for gloss varnishes. But there are also treatments for nails which penetrate directly into the nail and which, after application, “disappear”Almost immediately. People with nail biting problems often feel uncomfortable when others look at their nails.

Use as a base coat

The deciding factor here is whether the product should be used as a remedy or whether a manicure command is adequate. On the one hand, there are products that dry and matt the nail and therefore are not suitable as a base coat. On the other hand, many nail polishes need to be removed from the nails every other day by treatment with a solvent.

Here you have to ask yourself if you want to use a color varnish in addition to the treatment or if you want to do without color varnish for a few weeks and take care of your nails intensively with the best nail hardener. But there is also a wide range of nail hardeners that can be safely used as a base coat.

Durability on nails

The best nail hardener, which is used as a base coat, often extends the durability of the top layer of nail polish. The advantage is that it not only protects the nail against discoloration, but also prolongs the life of the color varnish.

However, some nail hardeners also have the opposite effect and can flake off relatively quickly, so that the real effect of nail hardening is again absent.

The durability of these products is not easy to determine, as it is generally a subjective perception. Reviews and experiences from consumers who have already thoroughly analyzed the various products are particularly useful.

Additional packaging

The packaging serves to protect the product on the one hand and to improve the general appearance of the best nail hardener on the other. Hardeners purchased online are generally not only delivered in glass bottles, but are also packaged.

The extra package almost always contains a note about the potential side effects and the ingredients contained therein. The most important warnings and instructions for use should also be disclosed.
