INCI is one of the most important elements on cosmetic packaging – and at the same time the most incomprehensible for consumers. For some, it's a string of unfamiliar chemical names, for others, the only reliable source of information about product quality.
As a cosmetologist and formulator, I know one thing: if you learn to read INCI, you will stop buying cosmetics "on promises" and start choosing them consciously – according to your skin's real needs.
In this article, I explain:
- what exactly INCI is,
- how to read the ingredients list step by step,
- what to look for in INCI and what not to demonize,
- how to distinguish a marketing ingredient list from an effective one,
- and what a well-structured INCI looks like using Orientana cosmetics as an example.
What is INCI?
INCI (International Nomenclature of Cosmetic Ingredients) is the international naming system for cosmetic ingredients, mandatory in the European Union and many countries worldwide.
Every cosmetic approved for sale must have:
- a full INCI list,
- written according to specific rules,
- identical regardless of the country of sale.
INCI is not a marketing description. It is an objective list of raw materials that were actually included in the product.
Why is INCI more important than the description on the front of the packaging?
Phrases like:
- "natural",
- "eco",
- "bio",
- "clean beauty"
are not legally regulated to the same extent as INCI.
It is in the ingredient list that:
- you can check whether the cosmetic actually contains the declared active ingredients,
- you will see their real concentration (by order),
- you can assess whether the formula makes technological sense.
Therefore, in expert brands such as Orientana, INCI is a starting point, not an addition to marketing.
How to read INCI? The most important rule of order
Ingredients in INCI are listed from the highest to the lowest concentration - down to 0.01%.
This means that:
- the first 3-5 ingredients form the base of the cosmetic,
- active ingredients in the middle of the list have real significance,
- everything at the end is present in small quantities
Why is the order in INCI crucial?
If you see:
a plant extract in 18th place, and marketing screams that it is the "main ingredient",
then... you have every right to be skeptical.
Does the first ingredient in INCI always have to be water?
Most often, yes - Aqua is the base of most cosmetics.
But pay attention:
in modern formulas, more and more often:
- part of the water is replaced by hydrolates,
- plant juices,
- bioferments.
For example, in Orientana cosmetics, the base is often functional, not "empty":
- aloe,
- ferments,
- adaptogenic extracts,
which genuinely support the skin, rather than just "diluting" the formula.
How to distinguish an active ingredient from a base in INCI?
An active ingredient is one that:
- has confirmed biological activity,
- affects the skin (hydration, regeneration, barrier, anti-aging),
- is present in an effective concentration.
Examples of active INCI ingredients:
- adaptogens (ashwagandha, reishi, tremella),
- vitamins (C, E, niacinamide),
- ceramides,
- acids,
- peptides.
Practical example
In the Orientana line serum:
Reishi is not a marketing additive, but one of the key ingredients in the formula, supporting skin immunity and reducing oxidative stress.
This is precisely what you should be able to spot in INCI.
Do Latin names in INCI mean chemistry?
No.
This is one of the biggest myths.
Plants in INCI are recorded:
- in Latin,
- according to pharmacopoeia,
- in a standardized form.
Chamomilla Recutita Flower Extract is simply chamomile.
Curcuma Longa Root Extract is turmeric.
Withania Somnifera Root Extract is ashwagandha.
Latin does not mean synthetic, it means precision.
INCI and natural cosmetics - can they be reconciled?
Yes, provided that:
the brand doesn't engage in "greenwashing",
and formulas are created by technologists, not just marketers.
Natural cosmetics
- must also have INCI,
- also use preservatives (safety!),
- also benefit from modern biotechnological solutions.
Orientana is a good example of a brand that:
- combines Ayurvedic plants,
- with modern cosmetic technology,
- without pretending that the cosmetic is a "herbal infusion."
Is a short INCI list always better?
Not always.
A short ingredient list:
- can be an advantage for very sensitive skin,
- but does not guarantee effectiveness.
A well-structured INCI:
- has a logical structure,
- a clearly defined function for each ingredient,
- a balance between the base, actives, and formula stability.
In cosmetology, the sense of the composition matters, not its length.
What not to demonize in INCI?
Google and social media have harmed many ingredients.
Not every:
- alcohol,
- preservative,
- emulsifier
is bad.
For example:
- Cetyl Alcohol is an emollient - found, for example, in moisturizing cosmetics
- preservatives protect the skin from bacteria,
- emulsifiers determine the stability and comfort of the product.
In Orientana cosmetics, auxiliary ingredients are:
- selected for sensitive skin,
- compliant with EU standards,
- and used in safe concentrations.
Most frequent questions about INCI
Does INCI tell you everything about a cosmetic?
No, it tells you about the ingredients, but not about the quality of raw materials, technology, and formula stability.
Can the order of ingredients be manipulated?
No, it is legally regulated.
Does INCI reveal concentrations?
Indirectly, through the order.
Do two cosmetics with similar INCI work the same way?
No, the quality of raw materials and the technological process matter.
Does the INCI of a natural cosmetic look "scarier"?
Often, yes – because it contains more extracts and ferments.
Is it worth learning to read INCI?
Definitely yes – it's the best investment in conscious skincare.
INCI as a tool for conscious skincare
INCI is not an enemy.
It is the language of cosmetology, which – once understood – gives a huge advantage.
Thanks to it:
– you don't buy cosmetics "on promises",
– you choose products suited to your skin,
– you understand why a given cosmetic works.
If you want to reach for formulas where INCI makes technological and skincare sense, it's worth paying attention to expert brands – such as Orientana, which build their compositions based on knowledge, not TikTok trends.
