It is a product that should be applied before make-up, with clean skin. Its main goal is to neutralize, protect and prepare the skin to receive the following layers.

It has a creamy, gel or even liquid texture, and is usually oil-free, being easily absorbed by the skin.

Which are the advantages of the primer?

There is no lack of advantages of primer. This is a cosmetic that, although not always used, makes all the difference in the preparation of the skin.

Basically, its function is to guarantee a good aspect to your face so that the make-up aesthetics is amplified. It neutralizes the skin tone, disguises spots and expression lines, diminishes the oiliness of the face and guarantees a very smooth texture.

It also has the advantage of working as an excellent fixative, ensuring that your make-up remains intact for many hours.

It is also worth mentioning that the primer disguises the pores and prevents your make up from cracking, leaving it always very natural, as if it had just been done.

Finally, the primer is not heavy and is quickly absorbed by the skin. Some of them even have moisturizing factor and protection against ultraviolet rays, being an excellent choice for those looking for a more advanced result.

For lipstick lovers, it is interesting to mention that there are also primers specifically for mouths, which also increase lipstick fixation and moisturize the lips.

Primer or facial serum: What are the differences?

Despite the striking differences, many people are confused about the functionalities of primer and serum, and so we will punctuate in detail all their differences.

The primer, as we have already said, is a beauty product that promotes immediate results. It should be applied on the skin before applying makeup, as a way to prepare the face, neutralize possible spots, reduce oiliness and disguise expression lines.

Its main function is the momentary aesthetic, and even though some of them have moisturizing factor, they cannot be considered treatment cosmetics.

The serum works in a different way. Unlike the primer, it has a long-term action and is a treatment cosmetic.

It is a fluid with high concentration of active ingredients and fast absorption by the skin, whose main function is to moisturize and care for the face as a whole.

It is known for its intense hydration, cell renewal, regeneration of collagen fibres, anti-ageing action and lightening of unwanted spots. It is important to mention that all these results are only noticed in the long term, with daily use of the product.

In summary, both are very effective in their proposals, and the ideal is that you use them together.

The serum always in the morning, after cleansing and preparing the skin, and the primer before applying makeup, with a clean face.

Buying criteria: how to compare primer models

Before you hit the hammer on which primer will be your choice, we recommend you pay attention to some factors that can make a difference in its use. Below, we punctuate some of them:

So that you don’t have any doubts left, we’ll tell you what should be observed in each of them:


The primers may be creamy, in gel or even liquid, so it is very important that they have a light and soft texture, without leaving a heavy skin sensation.

Prefer an option that has good absorption and that in a few seconds is uniformed on the face.

They should not, under any circumstance, leave your skin looking greasy or exaggerated, since it is a delicate cosmetic, without considerable pigmentation and with low coverage.


You can buy your primer in different formats: tube, in small cream jars and in glass valve with pump. It is a matter of taste and adaptation.

Here, we should mention that although the simplest formats are the most practical, it is a merely aesthetic factor, which does not influence the quality of the product.


The performance of any beauty product is a point that should be taken into account. Cosmetics are not always cheap, and that is why it is so important to spend in a conscious way, making the best choice in terms of cost-benefit.

In the case of primer it is no different. Before finalizing the purchase, observe the size of the package and how much product is available.

It is interesting that you buy a primer with good performance, that is worth the money you are paying and that will not last only a few weeks.


The great objective of a primer is not to hydrate the skin, however, that does not mean that it cannot have, in its composition, actives that guarantee a healthy and young skin.

We recommend that you opt for primers that are composed of vitamins and other factors, such as Panthenol. It is also interesting to prioritize those that have a protection factor against the sun.
