The RootsGuard Clean Standard™
Radically Pure. Rooted in Truth.
We formulate based on what skin actually needs — not how it looks on the surface.
The standard
What is the
RootsGuard Clean Standard™?
The RootsGuard Clean Standard™ is a formulation standard that guides our product development process. It guides which ingredients we use and why, what we exclude and why, and how we think about what goes into every formula and why.
If you want to understand what guides our ingredient choices and the thinking behind our formulas, this is the right place to start.
Why "clean" is not enough — and what we mean by "Pure"
The term "clean beauty" is now so broadly applied that it has become functionally meaningless. There is no regulatory definition of clean skincare in the EU, the US, or most other markets. Brands define the term themselves, which means it reflects marketing intent, not formulation rigour.
At RootsGuard, we use the term Radically Pure to describe a specific standard — not a vibe or a value statement.
By ‘Radically Pure’, we mean:
Every ingredient is selected for a clear purpose. What it does for your skin, and why it belongs in the formula.
Natural and lab-derived ingredients are held to the same standard: what it does, how clean it is, how it is understood to perform, and any known safety considerations.
Natural does not automatically mean safe. Some botanical ingredients, certain plant extracts and essential oils, can cause skin reactions, particularly in sensitive skin. We review natural ingredients with the same scrutiny as synthetic ones. We also disclose all ingredients so you can review the full ingredient list for your own needs or any concerns. Please always read the ingredients and do a patch test — the needs of every person are individual, and we formulate with care, but sometimes even honey can be detrimental to certain people.
We look at the full formula, not just each ingredient in isolation. Ingredients that are individually appropriate can still interact in ways that may not be optimal for the skin. The whole picture matters.
This standard reflects how we approach formulation decisions, based on current understanding and applied with judgement in the context of each formula.
Formulation approach
Nature-first.
Boosted by science where it counts.
RootsGuard formulas are built on a plant-based foundation. Botanical oils, plant extracts, and naturally derived actives form the base of what goes on your skin.
Where a plant-based ingredient can do the job well, we use it. Where science offers a more reliable or consistent approach, we may choose that instead.Guided by the same question: is this good for skin, long term?
What "skin-identical" means
Some ingredients are produced in a lab but are structurally identical to what your skin already makes or recognises. Your skin does not distinguish origin — it responds to structure. These are examples of the lab-derived ingredients we use, selected because skin recognises and responds to them naturally.
Ceramides: the same lipid molecules your skin naturally uses to hold its protective barrier together. We use them because they are structurally familiar to skin — recognised rather than foreign.
Hyaluronic acid: a molecule your skin produces naturally to retain moisture. Ours is derived through fermentation and selected for how it interacts with the skin's surface and deeper layers.
Niacinamide (Vitamin B3): a well-researched skin vitamin, widely studied for its role in supporting the skin barrier, sebum balance, and skin tone.
Peptides: small molecules that communicate with skin cells. We select peptides based on their specific function and their compatibility with the skin, not trend or marketing.
Our approach to using lab-derived ingredients
It is selected where it is structurally similar to something the skin naturally produces or recognises
It is selected based on available research supporting its function
We prioritise plant-based alternatives where they deliver a comparable result
It is reviewed for safety, including known sensitisation, hormonal, and accumulation considerations, based on available data
These are the principles we apply when making formulation decisions, not a fixed specification, but a standard we apply with judgement.
Nature first. Science where it genuinely helps.
How we compare
The RootsGuard standard
vs the industry.
| Criteria | Conventional Clean Beauty | COSMOS / EcoCert | RootsGuard Clean Standard™ |
|---|---|---|---|
| Definition of "clean" | Brand-defined, no minimum standard | Certification body criteria | Our own formulation standard, shared publicly on this page |
| Natural origin requirement | Loosely applied or undefined | ≥95% natural origin required | Nature-first; lab-derived ingredients used where structurally similar to what skin recognises and where they meaningfully support the formula |
| Excluded ingredients | Variable, brand-defined | Certification body list | A growing list of ingredients generally excluded under our formulation standard, regardless of regulatory approval or certification status |
| Synthetic fragrance | Often permitted or hidden as "parfum" | Restricted or excluded | We do not use synthetic fragrance in our formulations. Where fragrance is present, it is exclusively from natural botanical origin. EU cosmetics regulations require all fragrance blends — including natural ones — to be declared as "Parfum" on the label. Our Parfum declarations are COSMOS-certified natural origin blends. |
| Phenoxyethanol | Commonly used | Restricted, often permitted at low levels | Not aligned with our formulation standard. We use naturally derived preservation systems. |
| Silicones | Frequently used | Excluded under COSMOS | Not permitted under our standard. |
| Essential oils | Not systematically reviewed | Not systematically reviewed | Used selectively. Used selectively. Natural-origin essential oils are evaluated individually for skin compatibility and used at appropriate concentrations. |
| Peptides | Unregulated | Largely excluded | Selected based on available evidence for their function and compatibility with the skin |
| Third-party safety testing | Optional | Required for certification | Independent safety assessment per EU Cosmetics Regulation 1223/2009 |
| Formulation philosophy | Surface effect, trend-driven | Compliance-focused | Purpose-driven: ingredients chosen for what they do, not trend or marketing |
This comparison reflects our formulation intentions and the standards we set for ourselves, not a certification claim or a legal specification.
Manufacturing & Safety
Products assessed
before they reach you.
RootsGuard products are manufactured in laboratories operating in line with the safety and compliance requirements of EU Cosmetics Regulation 1223/2009, and assessed by independent EU-qualified safety assessors before being placed on the market.
Third-party safety assessment
Conducted by an independent EU-qualified safety assessor per Article 10 of EU Cosmetics Regulation 1223/2009. Mandatory under EU law. Documented in each product's Cosmetic Product Safety Report (CPSR).
Stability testing
Stability testing to evaluate formula integrity, pH stability, and microbiological performance across the product's expected shelf life.
Dermatological compatibility
Dermatological compatibility assessment may be conducted on selected products as part of the safety evaluation process.
Microbiological testing
Testing to evaluate preservation efficacy under simulated use conditions throughout the product's shelf life.
Full INCI labelling
Ingredients listed transparently by INCI name. Where EU regulations require a collective declaration — such as Parfum for fragrance blends — we explain what this means for our products on this page.
Efficacy testing
For selected hero products, we may conduct independent consumer usage studies to assess real-world performance over a defined period of use. Participants use the product under normal conditions and results are assessed at set intervals.
Where we make a performance claim, it reflects ingredient-level research or product usage study data.
Where study data exists for a specific product, it may be referenced directly in product's description on the product pages in our shop.
Excluded ingredients
Ingredients
generally excluded under our standard.
We generally exclude a range of ingredients, including many marketed as safe or natural, because not all natural is good for your skin. Our standard is not defined only by what we exclude. It is defined by what every included ingredient must have: a clear purpose, a safety profile we are comfortable with, and no publicly known concerns for long-term skin health.
These categories are generally excluded under our formulation standard, based on our current approach and ingredient review criteria.
Skin biology
How we think
about how skin works.
RootsGuard formulas are not built around trends or surface effects. They are built around our understanding of how skin works — and what it may need from a product.
The skin barrier — why it matters
Your skin has a natural protective layer — a barrier that keeps moisture in, keeps irritants out, and maintains the slightly acidic environment that keeps your skin balanced and your microbiome healthy.
A healthy barrier is not just a concern for sensitive skin. It is the foundation for every skin function — hydration, firmness, clarity, and your skin's ability to respond to the products you use. When it is compromised, skin finds it harder to stay balanced, hydrated, and responsive.
What many skincare products get wrong
Some common skincare ingredients can compromise the skin barrier even when marketed as beneficial. Harsh cleansing agents that strip the skin's natural oils. Alcohol-heavy formulas that dry out the surface. Synthetic fragrance that triggers low-level irritation over time. Occlusive ingredients, such as certain silicones, that may sit on the surface of the skin without directly contributing to its underlying function. The product may feel good on application, but the long-term effect on the skin may not always be beneficial.
How we formulate differently
pH compatibility
Our formulas are developed to be compatible with the skin's natural pH range — the slightly acidic balance that keeps the skin's surface functioning as it should.
Moisture retention
We aim to avoid ingredients that may compromise the skin's ability to retain moisture. Keeping water in the skin is one of the most important things a formula can do.
Ingredient compatibility
Moisturising and conditioning ingredients are selected for how well they work with the skin's natural structure — not just how they feel on application.
Microbiome awareness
Preservation systems are chosen to protect the formula from contamination while aiming to minimise disruption to the skin's natural bacterial balance.
Sensitisation review
Ingredients are reviewed for known sensitisation risk. Those that raise concerns under our review are generally not used, regardless of whether they are approved or widely used elsewhere.
Active ingredient purpose
Active ingredients are selected for a clear purpose within the formula, based on what they are understood to do for the skin, based on available research. Not for marketing appeal.
Who we're for
For those who have
started asking questions.
RootsGuard is for people who have looked at what is in their food, their water, their household products, and their skincare — and reached the same conclusion: the standard most of the industry operates to is not the standard they want for their bodies.
They understand that the skin is not a surface to be treated in isolation. It is the body's largest organ — an interface between the internal and the external. They are not willing to reduce their exposure to synthetic chemicals in every other area of their life and then apply a long list of synthetic compounds to their face twice a day.
People who read INCI labels and want to understand what they are reading and why each ingredient is there.
People who are mindful of what they put on and in their bodies, and who think carefully about the ingredients in their skincare — the same way they think about their food.
People who want skincare that supports their skin rather than just managing the surface — whether their primary concern is skin resilience, visible ageing, clarity, or long-term skin health.
People who have done the research, or who are looking for a brand that takes these questions as seriously as they do.
People who understand that regulatory permission and personal product standards are not always the same thing, and that ingredient scrutiny still matters.
RootsGuard does not appeal to everyone. It is designed for the person who has already decided that their skin deserves the same level of scrutiny they apply to everything else they put in and on their body.
Label transparency
How to read
a RootsGuard label.
Every ingredient is listed by its full INCI name in descending order of concentration. We aim to be transparent about what is in each formula. A brief guide:
Aqua / Water
Listed first when water is the primary ingredient — highest concentration.
Botanical actives
Listed by Latin botanical name. Rosa Canina Fruit Oil = rosehip oil. Centella Asiatica Extract = cica. Search any INCI name on the EU CosIng database for the full safety profile.
Skin-identical actives
Where lab-derived ingredients are used, we explain what they are and what they do in our product descriptions.
Preservatives
Our preservation systems are selected based on our formulation standard and listed on each product label.
If you have a question about a specific ingredient, contact us and we will answer directly.
Knowledge base
Research, explained
by someone who took it seriously.
The RootsGuard blog is where I share what I continue to learn. I am not a doctor, a dermatologist, or a medical consultant, I do not approach this as a medical professional. I am someone who went deep into the science of skin biology, ingredient function, and the relationship between internal health and skin behaviour, out of personal necessity, and then out of genuine passion. What I found, I documented. What I documented, I share.
The blog covers skin biology in accessible, referenced language: how the barrier functions, what disrupts it, how the microbiome influences skin behaviour, what the research says about specific actives, and how to read and evaluate an ingredient list without a chemistry degree.
Nothing on the blog is medical advice,the content is intended for educational purposes. It is research, explained clearly, by someone who took it seriously. If something I write prompts you to investigate further, speak to a qualified practitioner, or simply make a more informed choice about what you put on your skin — that is exactly the point.
The RootsGuard Clean Standard™ was not designed to satisfy a certification body or to appeal to a market trend. It was built from the ground up based on our understanding of what skin needs — and what we believe most skincare products are not yet designed to address.
Diana Luca Founder, RootsGuardFrequently asked questions
Everything you need to know
about our standard.
About the standard
Some ingredients they permit do not meet our own criteria. Certain synthetic preservatives that are COSMOS-approved, for example, do not align with our formulation values. Processing-derived compounds that can carry contamination byproducts, regardless of their natural source, are something we generally avoid under our formulation approach. And natural ingredients that serve no active skin function, colorants, pigments, decorative minerals, petroleum-derived ingredients like mineral oils and paraffin, we generally exclude because an ingredient that cannot be justified by what it does for skin does not belong in the formula. Natural or not.
It is also worth noting that our standard moves in both directions. Where we use skin-identical peptides and certain lab-derived actives that COSMOS and EcoCert largely restrict, we make a deliberate choice based on our own formulation values. These ingredients are not natural in origin, but they are structurally identical to what skin produces naturally, well-researched, and selected for a specific skin function. We apply our own criteria, rather than deferring in either direction to what certification bodies permit or restrict.
Our standard is based on our formulation values. Not on what a certification body defines as acceptable.
About ingredients
There is also an important argument for skin-identical ingredients when formulating for sensitive skin. Natural compounds carry their full botanical complexity, including compounds that can trigger reactions in susceptible individuals. Peanuts are natural. Citrus is natural. Latex is natural. All are common allergens. A skin-identical molecule, by contrast, is structurally defined — recognised by the skin rather than likely to provoke a response. We cannot anticipate every personal sensitivity, but choosing structurally defined ingredients where they exist may help reduces that risk.
Non-toxic skincare is not a regulated term, but in practice it describes formulations built around ingredients that are clean, purposeful, and designed to minimise exposure to compounds associated with potential long-term concerns.
At RootsGuard, non-toxic skincare means:
- No synthetic compounds added without a clear skin purpose
- No synthetic fragrance or undisclosed compounds
- Ingredients are selected to minimise potential long-term exposure concerns
- Ingredients are selected with consideration for skin barrier and microbiome compatibility
Formulas are built using plant-derived actives and skin-identical ingredients that the skin recognises and is compatible with — with an eye not only on immediate cleanliness, but on long-term skin health.
