INCI kódy: Co skrývají složky vaší kosmetiky a jak je číst

When you pick up a cream, serum, or shampoo, you see a list of strange names—INCI kódy, mezinárodní názvy složek kosmetických produktů, které musí být uvedeny na etiketě podle evropských předpisů. Also known as mezinárodní názvy ingrediencí, they are the only reliable way to know what’s really in your skincare, not just what the marketing claims. These aren’t secret codes—they’re standardized labels designed to tell you exactly what’s in the product, no matter the brand or country. But most people skip them, assuming that if it’s sold in a store, it must be safe. That’s a dangerous assumption.

Let’s say you’re looking for a moisturizer without parabens. You check the front label: "100% natural," "no chemicals." But if you flip it over, you’ll find methylparaben, konzervant, který se používá k prodloužení životnosti produktu a může vyvolávat alergie nebo rušit hormonální rovnováhu listed as ingredient #3. Or you might see sodium lauryl sulfate, pěnivá látka, která může sušit pokožku a způsobovat podráždění, zejména u citlivé pokožky hiding under the name "SLS." These aren’t rare ingredients—they’re everywhere. And if you don’t know how to read the list, you’re just guessing.

INCI kódy are listed in descending order by concentration. That means the first five ingredients make up the bulk of the product. If water is first, it’s mostly water. If aloe vera is second, it’s a decent amount. But if you see a long list of unpronounceable names before any natural ingredient, you’re buying mostly synthetic fillers. It’s not about avoiding all chemicals—it’s about avoiding the ones that irritate, dry out, or disrupt your skin’s balance. You don’t need to memorize 1,000 names. Just learn the top 10 troublemakers: parabens, sulfates, phthalates, mineral oil, synthetic fragrances. They’re the ones that show up in post after post here, from škodlivé látky ve vlasech to červené fleky na obličeji.

And here’s the kicker: just because a product says "hypoallergenic" or "dermatologist tested" doesn’t mean it’s safe for you. Those terms aren’t regulated. Only INCI kódy are. That’s why every guide on this site—from rybí kolagen to hyaluronové sérum—starts with checking the label. Because no amount of expensive marketing can fix a product that’s full of irritants.

What you’ll find below are real, practical posts that show you exactly how to decode those labels. You’ll learn how to spot the hidden nasties in your shampoo, why some "natural" products are worse than conventional ones, and how to pick a moisturizer that actually works for your skin type—not just for your Instagram feed. No fluff. No jargon. Just clear, actionable info based on what people actually experience when they start reading their ingredient lists.
