I created RootsGuard to set a new standard one rooted in truth, not trends. In this article, I share exactly what that means.
The RootsGuard Clean Standard™ is our formulation standard the principles that guide how we select ingredients, what we avoid, and how we think about what goes into our products. It is not a marketing label. It is how we actually work.
If you want to understand what guides our ingredient choices and the thinking behind our formulas, this is the right place to start.
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.
Radically Pure means:
Every ingredient is selected for a clear purpose what it does for your skin, and why it belongs in the formula.
Both natural and lab-derived ingredients are held to the same standard: what it does, how clean it is, and whether it has any known risks or research data for skin reactions, hormone disruption, or long-term skin or heath damage.
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 fine can still interact in ways that are not good for skin. The whole picture matters.
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 has found a way to deliver something more reliably, we use that instead. Guided by the same question: is this good for skin, long term?
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.
These are the principles we apply when making formulation decisions not a fixed specification, but a standard we hold ourselves to.
Nature first. Science where it genuinely helps. Nothing in between.
| 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 |
| Natural origin requirement | Loosely applied or undefined | ≥95% natural origin required | Nature-first; lab-derived ingredients only when structurally identical to what skin already recognises |
| Excluded ingredients | Variable, brand-defined | Certification body list | A growing list of ingredients excluded regardless of regulatory approval or certification status |
| Synthetic fragrance | Often permitted or hidden as “parfum” | Restricted or excluded | No synthetic fragrance. Where fragrance is present, it is exclusively from natural botanical origin. Our Parfum declarations are COSMOS-certified natural origin blends. |
| Phenoxyethanol | Commonly used | Restricted, often permitted at low levels | Not permitted under our 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. Only natural-origin essential oils, evaluated individually for skin compatibility and used at concentrations consistent with safety data. |
| Peptides | Unregulated | Largely excluded | Selected for evidence-based function and skin compatibility |
| 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.
RootsGuard does not rely on marketing definitions of ‘clean.’ Our standard is written, publicly available, and goes beyond what most certifications require.
RootsGuard products are manufactured in laboratories that meet the safety and compliance requirements of EU Cosmetics Regulation 1223/2009, assessed by independent EU-qualified safety assessors before reaching 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: testing to evaluate formula integrity, pH stability, and microbiological performance across the product’s expected shelf life.
Dermatological compatibility: dermatological compatibility assessment is conducted on selected products as part of the safety evaluation process.
Microbiological testing: testing to confirm 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.
For selected hero products, we 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 on a product page, it reflects ingredient-level research or product usage study data not marketing language. Where study data exists for a specific product, it is referenced directly in that product’s description.
We do not use 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 known concerns for long-term skin health.
Synthetic fragrance / Parabens / Phenoxyethanol / SLS & SLES / Mineral oils / Silicones / Synthetic dyes / Titanium dioxide / Hydroquinone / Aluminum compounds / Talc / Carmine / PEG compounds / Formaldehyde-releasing preservatives / Mica (leave-on formulas) / Eugenol at high concentration / High-concentration plant enzymes
RootsGuard formulas are not built around trends or surface effects. They are built around our understanding of how skin works and what it actually needs from a product.
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.
Many 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 unnecessary, we may use ethanol at meaningful concentrations only for a specific functional purpose, such as supporting active ingredient penetration in targeted treatment products.
Synthetic fragrance that triggers low-level irritation over time.
Occlusive silicones that sit on top of the skin without contributing to its actual health. The product feels good. The skin pays for it later.
Moisture retention: we avoid ingredients known to 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 without unnecessarily disrupting the skin’s natural bacterial balance.
Sensitisation review: ingredients are reviewed for known sensitization risk. Those that raise concerns under our review are not used, regardless of whether they are approved or widely used elsewhere. However you should now that any essential oil can have allergens, and those are all disclosed on the product labels and on the products pages..
Active ingredient purpose: active ingredients are selected for a clear purpose what they are understood to do for the skin, based on available research. Not for marketing appeal.
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 what is permitted is not the same as what is safe, and that the absence of a warning does not mean the absence of a risk.
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.
Every ingredient is listed by its full INCI name in descending order of concentration. We aim to be transparent about what is in every formula. A brief guide:
Aqua / Water listed first when water is the primary ingredient; concentration is highest.
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 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 naturally derived and listed on every product label.
If you have a question about a specific ingredient, contact us and we will answer directly.
The RootsGuard blog is where I share what I continue to learn.
I am not a doctor, a dermatologist, or a medical consultant. 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. 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.
With unwavering commitment,
Diana
Founder, RootsGuard
The RootsGuard Clean Standard™ is a formulation system that defines which ingredients are used, which are excluded, and how every skincare formula is evaluated for long-term skin compatibility.
Unlike “clean beauty,” which has no legal definition, RootsGuard applies a, evidence-based standard that excludes over high-risk ingredients and prioritizes plant-derived actives.
Most clean beauty brands rely on marketing claims and loosely defined ingredient lists. RootsGuard uses a strict, documented formulation standard based on skin biology and clinical evidence.
RootsGuard differs by:
This makes RootsGuard a mechanism-based skincare system, not a trend-driven “clean” label.
Biomimetic ingredients are molecules designed to be structurally identical to substances naturally found in the skin.
Examples include ceramides, hyaluronic acid, and niacinamide (vitamin B). These ingredients work effectively because the skin recognizes their structure and can use them directly.
In RootsGuard formulations, biomimetic ingredients are only used when:
This ensures compatibility with the skin’s biology.
Phenoxyethanol and synthetic fragrance are commonly used in skincare but are associated with potential irritation, sensitization, and long-term exposure concerns.
Synthetic fragrance can contain undisclosed compounds under the label “parfum,” making it impossible to fully assess risk.
RootsGuard excludes both entirely and uses:
This reduces unnecessary exposure and supports long-term skin health.
RootsGuard excludes over 150 ingredients that do not meet its safety and compatibility standards.
These include:
The skin barrier controls hydration, protects against external stressors, and regulates the skin microbiome.
Many skincare products damage the barrier through:
When the barrier is compromised, the skin becomes more reactive, dehydrated, and prone to inflammation.
RootsGuard formulas are designed to support barrier function by maintaining pH balance, reducing TEWL (transepidermal water loss), and using lipid-compatible ingredients.
A skincare formula is safe long-term when it supports the skin without disrupting its natural functions.
Key factors include:
Yes. RootsGuard has a specific line of products (Solo Paola Line) designed to be compatible with sensitive and reactive skin, including rosacea-prone skin.
Formulas avoid:
Instead, they focus on:
However, individual sensitivity can vary, so patch testing is always recommended.
Skin naturally maintains a slightly acidic pH between 4.5 and 5.5.
Products outside this range can:
Most RootsGuard formulas are buffered within the optimal 4.5–5.5 pH range to maintain barrier integrity. Targeted active treatments (such as our BHA toner) are formulated at the pH required for active efficacy, with use guidance to support barrier protection during their application phase.
Radically Clean is how we describe our formulation standard — not a vibe or a brand positioning line. It means every ingredient is selected for a documented function, not for aesthetics, fragrance, or cost. It means both natural and synthetic ingredients are evaluated against the same criteria: safety profile, skin compatibility, non-toxisity, no unnecessary additives, evidence of efficacy, and absence of documented sensitisation, endocrine disruption, or barrier interference risk. It also means the formula as a whole is assessed — because individually safe ingredients can interact in ways that compromise barrier function.
COSMOS and EcoCert set a floor — a minimum standard for certified clean manufacturing. The RootsGuard Clean Standard™ starts where certification ends. We ban ingredients that COSMOS and EcoCert permit — including phenoxyethanol, certain high-risk essential oils, and PEG compounds. Where we use biomimetic actives, our standard goes further than COSMOS allows, because our standard is based on skin biology, not what certification bodies require. Every product is manufactured under GMP-certified conditions and assessed per EU Cosmetics Regulation 1223/2009, regardless of manufacturing location.
Our formulas are built on a natural foundation: botanical oils, plant extracts, plant-derived humectants, fermentation-sourced compounds, and phytochemicals chosen for their documented skin-supportive function. Where nature delivers what the skin needs, that is what we use.
In certain products, we also include biomimetic and skin-identical actives. These are molecules structurally identical to compounds the skin already produces or recognises, such as niacinamide (vitamin B3), vitamin C, ceramides, hyaluronic acid, and selected peptides. They are added only when they bring something nature cannot reliably deliver on its own: stability, targeted performance, or improved penetration of the botanical actives that surround them. Each one is selected for purpose, not for trend.
Crucially, every biomimetic ingredient we use is held to the same purity standard as the rest of the formula. They are clean, free from the synthetic compounds, petrochemical derivatives, and toxins that we exclude across our entire range. Skin-identical does not mean compromise. It means we use what works, only when it works, and only when it meets our standard.
The exact natural percentage of each formula is disclosed on the individual product page, so you can see precisely what is in the product you are choosing, formula by formula.
Biomimetic ingredients are molecules structurally identical to compounds the skin naturally produces or recognises, synthesised under controlled laboratory conditions. The skin’s response to a molecule is determined by its structure, not its source. Examples we use include: skin-identical ceramides (ceramide NP, AP, EOP); fermentation-derived hyaluronic acid; and peptides. We never use biomimetic ingredients as cost-saving substitutes for botanical actives. Every biomimetic choice is made on the basis of skin biology and effectives of the formula.
Where a natural alternative exists that meets our standard of purity, stability, and efficacy at the required concentration, we use it. Biomimetic peptides are used only when: the molecule is structurally identical to a skin-native compound; there is peer-reviewed evidence for the specific function claimed; no natural alternative delivers equivalent performance; and the ingredient has no documented sensitisation, endocrine disruption, or accumulation risk.
We exclude over 150 ingredients. Key exclusions include: synthetic fragrance and parfum; parabens (all variants); phenoxyethanol; sodium lauryl sulfate (SLS) and SLES; mineral oils and petrolatum; silicones (all variants including dimethicone and cyclopentasiloxane); synthetic dyes; titanium dioxide; hydroquinone; aluminum compounds; talc; carmine; PEG compounds; formaldehyde-releasing preservatives; and high-risk essential oils with documented sensitisation profiles. The full list is available on request.
RootsGuard does not use synthetic fragrance or masking agents. Where a Parfum declaration appears on our INCI labels, it refers exclusively to a COSMOS-certified natural origin fragrance blend composed of essential oils, plant aromatic extracts, and hydrosols. We never use synthetic aroma chemicals, phthalates, or undisclosed synthetic compounds. The individual fragrance allergens that EU regulations require us to declare separately (such as Linalool, Limonene, Citronellol, Geraniol, Citral) are naturally occurring components of these botanical fragrance materials.
We use only natural preservation systems — selected to control microbial contamination without disrupting the skin’s broader resident microbiome. All preservatives are explicitly listed by their INCI name on every product label. There are no hidden preservation compounds in any RootsGuard formula.
Barrier integrity is not a concern exclusive to sensitive skin — it is the prerequisite for every skin function. A functioning stratum corneum regulates water loss, controls penetration of external substances, and maintains the acid mantle that supports the skin microbiome. A compromised barrier reduces the efficacy of every active ingredient applied to it, accelerates visible ageing, and prevents the skin from maintaining its own equilibrium. This is why every RootsGuard formula — whether it targets anti-ageing, clarity, sensitivity, or hydration — is designed with barrier compatibility as a baseline requirement.
Yes — for our hero products, we conduct independent clinical efficacy studies on human volunteers under controlled conditions. We do not make efficacy claims that are unsupported by peer-reviewed ingredient data at the concentrations used, or by product-level clinical assessment. Where clinical data exists for a specific product, it is referenced directly in that product’s description.
Every ingredient is listed by its full INCI name in descending order of concentration — the highest-concentration ingredient is listed first. Aqua or Water is listed first when it is the primary base. Plant-derived actives are listed by their Latin botanical name (Rosa Canina Fruit Oil = rosehip oil; Centella Asiatica Extract = cica). Biomimetic actives are listed by INCI name and explained in the product description. Preservatives are explicitly listed — there are no hidden preservation compounds. If you are unsure what an INCI name refers to, search it in the EU CosIng database (ec.europa.eu/growth/tools-databases/cosing) for the full safety and function profile. If you have a specific question about any ingredient, contact us directly.
