This post explains what NATRUE certification involves, why it matters more for children's products than adult ones, and how it fits into choosing age-appropriate skincare.
Why "Natural" Alone Isn't a Meaningful Claim
In the UK and EU, there's no legal definition of "natural" when it comes to cosmetics labelling. A product can call itself "natural" while containing only a small percentage of naturally derived ingredients, alongside synthetic fragrances, preservatives, or other additives. This gap between marketing language and actual formulation is exactly why independent certifications exist — to give parents (and all consumers) a verified standard to rely on, rather than taking a label's word for it.
What NATRUE Certification Actually Verifies
NATRUE is an international, non-profit certification body that sets clear criteria for natural and organic cosmetics. To be certified, a product must meet requirements across several areas:
• Ingredient origin — a defined minimum percentage of natural or naturally derived ingredients, with only permitted, carefully limited synthetic additives
• Manufacturing processes — natural ingredients must be processed using approved, minimally invasive methods that preserve their natural properties
• Prohibited ingredients — a strict exclusion list, including synthetic fragrances and dyes, silicones, PEGs (polyethylene glycols), and mineral oils derived from petroleum
• No animal testing — in line with EU cosmetics regulations
• Independent auditing — products are assessed and certified by NATRUE's accredited third-party certification bodies, not self-declared by the brand
This means a NATRUE-certified product has been externally verified against a fixed, published standard, rather than relying on a brand's own description of its formula.
Why This Matters More for Children's Products
For adult skincare, formulation choices are often about personal preference or specific skin concerns. For children's and tweens' products, the stakes are somewhat different: as covered in dermatologists' recent warnings about children using adult skincare, a developing skin barrier is more reactive and more easily irritated by synthetic fragrance, harsh processing residues, or unnecessary additives.
An independent certification like NATRUE gives parents a way to verify — rather than simply trust — that a product has been formulated with a genuinely verified, more natural ingredient profile, which is particularly reassuring when buying for a child rather than for yourself.
There's also a practical trust dimension here. Most parents don't have the time (or the chemistry background) to scrutinise a full ingredients list every time they buy a new skincare product. An independent certification acts as a shortcut — a signal that someone with the relevant expertise has already done that scrutiny, against a consistent, published standard, rather than a standard the brand set for itself.
How NATRUE's Standards Compare to General Cosmetics Regulation
It helps to understand that NATRUE certification sits on top of, rather than replaces, standard UK and EU cosmetics regulation. All cosmetics sold in the UK must already meet baseline safety requirements, including restrictions on certain substances and mandatory safety assessments. NATRUE certification adds an additional layer by restricting a wider range of synthetic ingredients, setting minimum natural content thresholds, and requiring specific, less invasive processing methods for natural ingredients. For parents comparing two products that both meet basic UK safety law, NATRUE certification is one clear way to distinguish a genuinely natural formulation.
What NATRUE Certification Doesn't Tell You
It's worth being clear-eyed about what certification does and doesn't cover. NATRUE verifies natural formulation standards — it isn't a guarantee against all possible skin reactions, since even natural ingredients (like certain plant extracts or essential oils) can cause irritation in some individuals. It also isn't a substitute for checking a product is specifically formulated and tested for the right age group, since a NATRUE-certified adult anti-ageing product would still be inappropriate for a tween's skin.
In other words, NATRUE certification and age-appropriate formulation are two separate, complementary things worth checking for together.
How to Verify NATRUE Certification Yourself
NATRUE-certified products display the NATRUE label directly on packaging, and the certification can be independently checked via NATRUE's own public directory of certified brands and products. This makes it straightforward for parents to confirm a claim rather than relying solely on brand messaging.
Dewy by Trilogy's Routine for Tween Skin
Dewy by Trilogy is certified natural by NATRUE across its full four-step routine, giving parents an independently verified standard alongside dermatological testing. Each product is formulated to a high naturally derived content: the Fresh Face Gel Cleanser and Dream Cream are both 99.2% naturally derived, while the Clear Up Toner and Spotless Serum are 99% naturally derived.
Beyond the certification itself, every product is built without the ingredients dermatologists have flagged as inappropriate for young skin — no fragrance, no retinol, no harsh exfoliating acids, no alcohol in the toner. Instead, the range relies on ingredients like Mānuka leaf extract, prickly pear cactus, rose myrtle, and New Zealand Mānuka honey to gently support tween skin through its natural hormonal changes. For parents who want more than a marketing claim of "natural," NATRUE certification provides a verifiable answer.
Frequently Asked Questions
Is NATRUE certification the same as "organic" certification?
Not exactly. NATRUE certification does not necessarily mean a product is organic. NATRUE certifies both natural and organic cosmetics, so some NATRUE-certified products contain higher levels of organic ingredients than others, depending on whether they are certified as natural or certified as organic.
Does NATRUE certification mean a product is hypoallergenic?
No — no certification, natural or otherwise, can guarantee a product won't cause a reaction in every individual, since even natural ingredients can trigger sensitivities in some people. NATRUE verifies formulation and sourcing standards, not an allergy-free guarantee.
Why do some genuinely natural brands not carry NATRUE certification?
Certification is a voluntary process that involves cost, time, and rigorous auditing, so some brands may formulate naturally without pursuing formal certification. That said, certification does provide independent verification that self-declared claims don't offer.
Is a NATRUE-certified product automatically safe for my tween's skin?
Not automatically — certification confirms natural formulation standards, but you'll still want to check the product is specifically designed for a tween's age group, rather than being a NATRUE-certified adult product with unsuitable actives.
How can I check if a specific product is genuinely NATRUE certified?
Look for the NATRUE label on the packaging, and you can cross-check this against NATRUE's own public certification directory online for added confidence.
Are synthetic ingredients always worse than natural ones for tween skin?
Not necessarily — some synthetic ingredients are mild and well-tolerated, while some natural ingredients can be irritating. NATRUE certification isn't a claim that synthetic equals bad; it's a verified standard for brands that have chosen to formulate predominantly with natural and naturally derived ingredients.
