Natural vs Synthetic Ingredients — What Does “Natural” Really Mean?
Natural or synthetic? Find out what “natural” really means in cosmetics, how to spot greenwashing and how to judge ingredient lists sensibly.
The word “natural” carries unusual weight in cosmetics today. For many people it sounds like a synonym for safety, simplicity and higher quality. The problem is that the label “natural” on its own doesn't always tell you exactly what's inside the packaging. In practice, a big gap can open up between marketing, certification, the INCI list and how a product actually performs.
That doesn't mean natural cosmetics are just a passing trend. Many of them have thoughtfully built formulas and meet real user needs. What matters is not to assume automatically that “natural” means better and “synthetic” means worse. In informed skincare, it's far more useful to ask about function, tolerance and ingredient transparency than to rely on the label alone. On PurScore you can weigh up these criteria using the Bio/Eco filter, the descriptions in our ingredient database and the naturalness ranking.
What does “natural” actually mean in a cosmetic?
In marketing language it tends to be a very broad term. For some brands “natural” means a high proportion of plant-derived raw materials; for others, the presence of a few extracts is enough. There are also certified cosmetics with more precise criteria, but even then it doesn't mean every single ingredient will be purely “straight from nature.”
Cosmetic formulation often uses processed substances, plant derivatives or nature-inspired ingredients that behave more stably from a technological standpoint than the raw material in its unaltered form. That's why simply dividing things into “natural” and “non-natural” rarely reflects a product's real quality.
Does synthetic mean worse?
No. “Synthetic” primarily describes how an ingredient is produced, not its automatic harmfulness. In cosmetics, many synthetic substances serve very practical functions: they increase the stability of a formula, improve preservation, allow for a gentler texture or reduce the risk of contaminants that can occur in natural raw materials.
On the other hand, natural ingredients aren't inherently perfect for every skin type either. Essential oils, plant extracts and naturally derived blends can cause irritation or allergies, especially in sensitive people. That's an important reminder, because many people assume that plant origin guarantees gentleness. It doesn't.
Where does greenwashing come from?
Greenwashing happens when a brand leans on associations with nature more in its messaging than in the actual formula. Green packaging, leaves on the label, slogans about purity and harmony with nature can all build certain emotions, but they don't replace an INCI analysis. Sometimes a cosmetic looks “eco,” while in practice it has a fairly standard recipe with a single plant additive.
That doesn't necessarily make the product bad. The real issue is more about a lack of transparency and creating the impression that the level of naturalness is higher than the ingredient list actually suggests. This is exactly why it's worth using rankings, ingredient descriptions and filters that help separate the marketing message from what's really in the product.
Does a natural cosmetic have to be better for your skin?
Not necessarily. For one person, a short, simple formula based on synthetic emollients and mild preservatives will work better. For another, a formula with a large share of plant oils and extracts will be ideal. What matters most is matching the product to your skin's needs, the type of product and the effect you're after — not the ideology behind the ingredients.
For example, reactive skin may tolerate heavily fragranced “natural” cosmetics poorly, while doing well with a simple, fragrance-free formula containing synthetic emollients. The same goes for hair care: an ingredient's origin doesn't always tell you as much as its function within a specific formula.
How to assess naturalness sensibly
It's best to look at several levels at once. First: what proportion of ingredients are of plant or mineral origin? Second: does the product avoid obvious marketing tricks and clearly state exactly what it contains? Third: is the ingredient list consistent with the brand's claims? Fourth: is the formula sensible in terms of function — for example preservation, texture and shelf life?
In practice, combining the Bio/Eco filter with an analysis of individual ingredients gives good results. It then becomes easier to see whether a cosmetic really does have a higher share of the raw materials you care about, or whether it's mostly relying on a marketing narrative about nature.
Why isn't the “natural” label alone enough?
Because it doesn't tell you whether the product will be effective, comfortable and well tolerated. It also says nothing about the proportions of ingredients or about which supporting substances were used to keep the formula stable and safe. Two cosmetics with similar front-of-pack slogans can differ in their formulas far more than the advertising suggests.
That's why it's best to treat “naturalness” as one feature among many, rather than the final verdict on quality. An informed purchasing decision comes down to combining several criteria: your skin's needs, the product's function, the simplicity of the formula, the presence of fragrance and the overall consistency of the formula.
How to use PurScore when choosing
If you care about products that come closer to the idea of naturalness, start with the naturalness ranking and filter your results. Then check in the ingredient database whether the extracts and oils promised on the packaging really hold a meaningful place in the formula. It's also worth comparing two similar cosmetics in the same category, because that makes it easy to see which one is genuinely more transparent.
This approach helps you avoid both an unthinking enthusiasm for naturalness and an unnecessary distrust of synthetic ingredients. In everyday shopping, it's precisely that balance that's most valuable.
The practical takeaway
“Natural” is not a magic word that guarantees a better cosmetic. Likewise, “synthetic” doesn't automatically mean something worse. A product's quality and value are determined by the whole formula, its function, the transparency of the messaging and how the cosmetic actually performs on your skin or hair.
Instead of being guided by the slogan alone, compare ingredient lists and check what really lies behind a brand's claims. Browse the Bio/Eco filter, see our ingredient explanations and make use of the naturalness ranking.

Not always. Naturally derived ingredients can also irritate or trigger allergies, and safety depends on the formula as a whole.
No. Many synthetic substances perform important technological functions and are well tolerated.
It's a situation where a brand's messaging suggests the product is more natural or eco-friendly than the actual ingredient list shows.
It's best to analyse the INCI list, use filters and compare products within the same category rather than trusting the slogans on the packaging alone.
