When faced with a cosmetic ingredient list, it's easy to feel lost. Botanical names in Latin, strange acronyms, technical words far removed from our daily experience. Added to this is the tendency of a certain type of marketing to demonize certain ingredients, often without scientific basis. 

Reading an INCI list should help us better understand what we are applying to our skin, which is our most intimate and personal possession: it's not a test to pass, where certain boxes must be checked and others not, but rather a map, a guide. Like all maps, it only becomes useful when we know how to read it.

In Europe, cosmetic ingredient names follow a standardized nomenclature, and the ingredient list is provided in descending order by weight down to the 1% threshold; below that threshold, the order may change. This means that the first positions tell us a lot about the formula's structure, while the last ones should be interpreted more calmly.

As a cosmetic and holistic wellness brand, one of warew's core values is transparency in communication with customers. We want all of you to have the tools to independently understand which product (not just ours!) is most effective for your skin.

That's why today we're taking you on a small journey through what's behind the cosmetic product you might be holding now, wondering what's inside.

So, let's begin!

What INCI really is

INCI is the acronym for International Nomenclature of Cosmetic Ingredients. In practice, it's a shared language by which cosmetics legally declare their ingredients, and you'll always find it on any cosmetic packaging approved for sale. 

A cosmetic label is an (almost) objective report, and to fully understand it, we need to learn to recognize the function of what we see: an aqueous base, a lipid component, a substance that helps the texture, a natural fragrance.

The point is to understand the meaning of the entire formula and why certain ingredients have been added when a certain type of marketing considers them "harmful."

Let's clarify one thing: no ingredient that is inherently harmful to our skin can ever end up in a cosmetic approved for sale in Europe. If it were, it would have been banned and properly regulated, don't you think? Of course, it has happened and will happen again that rules are updated, which generally leads to the withdrawal of affected products from the market in the most severe cases, not because they are necessarily harmful, but as a precautionary measure.

Rather, some ingredients may react poorly to a specific skin type, perhaps because they are not suitable for a particular problem, or even because they have been formulated in overly concentrated percentages.

You've probably bought a product with spectacular reviews, only to find that, once applied, your skin simply doesn't like it at all. This doesn't necessarily mean all the reviews were false: simply, every skin and every microbiome has its own particular balance. Just like people.

The first lines matter 

The most useful way to read an INCI is to start from the beginning. The first positions almost always tell the product's identity.

Let's take a product we all know, for example: warew Emulsion Aqua. In the first positions of the formula appear Ume water, Onsen-Sui, then ingredients like glycerin, squalane, and ceramides. This is consistent with what the product promises: a fresh and light emulsion, designed to restore the hydrolipidic film and support the barrier function, especially for combination or oily skin. 

Let's try with warew Cream Aqua. Here too, Ume water comes first, replacing pure water in our formulas, followed by Butylene Glycol and the much-feared Alcohol. Some might frown here, thinking of the common prejudice that alcohol in cosmetics "dries out" the skin. 

This is true, to a certain extent: alcohol can indeed damage the fats that make up the skin's barrier, but it is also a very important ingredient for any cosmetic due to its antibacterial action: in adequate concentrations (less than 5-7%), it acts as a preservative and evaporates even before reaching your skin. In practice, it all comes down to concentration, but if you have dry skin, a cream with the ingredient Alcohol lower on the list, like Cream Rich, might be better.

The purpose of INCI is to allow us to understand if the product's structure is consistent with its function. It's up to us, who know our skin best, to evaluate accordingly.

Japanese Ume plum distillate is key to the warew routine: its antibacterial and soothing properties make it the heart of all our formulas.

Natural is not enough

In contemporary cosmetics, there is often talk of natural ingredients, as if they alone were enough to define the quality of a cosmetic. In reality, a good formula is always the result of a balance between nature, formulation expertise, and intended use.

warew works precisely in this direction: our brand's products are formulated in the Yokohama research center, contain over 95% naturally derived ingredients, and are designed to support the physiological functions of the skin, respecting its balance.

We have chosen the ingredients that are part of our formulas primarily for their function: our products contain natural treasures, such as Snow Mushroom or Ume water, which have a long history in traditional Japanese medicine and are good not only for the skin but for the whole body.

Each product has a precise purpose and works in synergy with the next, as do its ingredients. When reading an INCI, therefore, the useful question is not "is this ingredient natural?". The right question is: does this ingredient make sense here, within this formula, for this skin type and for this moment in the routine?

The same INCI doesn't tell the whole story

There's also a less visible, but very important, aspect: two ingredients with the same INCI name are not automatically equal in quality.

The same raw material can have very different levels of purity, freshness, and presence of contaminants. With the same name on the label, the supply chain changes, the control changes, and the final result on the skin changes. This difference, unfortunately, is currently impossible to communicate via an INCI.

Think, for example, of wine: aside from small differences, the "INCI list" of a wine is always the same, essentially grape juice. However, we know very well that the grape juice used is not the same for all wines: each vineyard and variety has its unique characteristics, impossible to convey with a mere ingredient list.

The INCI is only one part of a cosmetic product's story; the other part concerns how that formula was designed, with what quality standard, and with what cosmetic vision.

In the case of warew, our vision combines Japanese tradition, selected ingredients, and advanced formulation. It's a difference that cannot be read in a single line, but is perceived in the coherence of the whole. 

What to really look for when choosing a cosmetic

If you want to read an INCI list more calmly, keep these four steps in mind:

1. Look at the beginning of the formula.
The first positions tell you if the product is more watery, more lipid-rich, richer, or lighter.

2. Ask yourself what the product is for.
A cleanser, an emulsion, and a cream shouldn't have the same type of composition because they perform different functions. In the warew routine, for example, the emulsion serves to restore the hydrolipidic film and create the optimal substrate for subsequent products, while the cream protects and better retains hydration. 

3. Don't demonize technical names.
A complex name does not automatically mean an ingredient is "bad." It often simply describes a precise function of stability, texture, or delivery. Do your own research independently, keeping in mind that every ingredient you find on the INCI list must, by law, be approved for use by European regulations. If it's not, your product is not compliant and should be avoided.

4. If you have sensitive skin, always check the complete formula.
All warew products are dermatologically tested for sensitive skin. However, this does not exclude the possibility that your skin may react negatively to specific ingredients. Especially if you already know you are allergic or sensitive to certain components, always check the complete ingredient list. It's the most serious and realistic way to approach INCI.

INCI is expertise, but also trust

Understanding a cosmetic doesn't mean becoming a formulator, but learning to ask better questions.

A good INCI list doesn't just contain reassuring words and "trendy" ingredients, but reflects a well-thought-out formula, consistent with the product's function, respectful of the skin, and supported by a reliable supply chain.

In the case of warew, this consistency is found throughout our ritual: from double cleansing, to the rebalancing emulsion, to the protective cream. An essential skincare, built to work with skin physiology and gently accompany it.

Reading the INCI list without anxiety is possible. Just stop looking for a list of perfect ingredients and start looking for a formula that makes sense for YOUR skin.
