Is natural skincare safe for sensitive skin? Here's what I learned

Updated: Jul 19

For many years, I trusted the word "natural."


I trusted it on ingredient labels, in wellness spaces, in communities full of people who cared about what they put on their skin. I assumed that if something came from a plant, it was at least safe for someone like me — someone with eczema-prone, reactive skin who had tried everything and was desperate for relief.


I was wrong. And learning that changed how I formulate Rooted+Wilder products.


Here's the short version, if you need it: many plant-derived ingredients, including linalool (found in lavender and bergamot) and other fragrance compounds from popular botanicals, are among the most common contact allergens in skincare. "Natural" and "safe for sensitive skin" are two different questions. That took me years, 80 chemicals taped to my back, and one accidental experiment to fully understand.

The Problem With "Natural"


The word "natural" has no regulated definition in the skincare industry. It doesn't mean fragrance-free. It doesn't mean allergen-free. It doesn't mean it's been tested for sensitive skin.


It means the ingredient originated from a natural source. That's all. Even that definition can vary from person to person.


And here's the thing about natural sources: they're full of bioactive compounds that the human immune system sometimes identifies as threats. Pollen is natural. Poison ivy is natural. And linalool, a fragrance compound found in lavender, bergamot, and hundreds of other beloved botanicals, is one of the most common contact allergens in skincare.


What I Found on My Own Back


After years of trying elimination diets, supplement protocols, and a parade of "gentle, natural" skincare products, I finally sat in an allergist's office with 80 different everyday chemicals taped to my back.


This is called a contact allergy patch test, and most people don't know it exists. It's different from the standard allergy testing you might have done for environmental allergens. Patch testing specifically identifies contact dermatitis (which is just a technical way of saying reactions caused by direct skin contact with certain chemicals, not airborne or food triggers).


48 hours later, I had two reactions: isopropyl myristate and oxidized linalool.


Isopropyl myristate is a synthetic emollient used widely in moisturizers, sunscreens, and makeup primers. It gives products a smooth, silky texture. It can also clog pores and trigger immune responses in some people.


Linalool was the more surprising one. It's naturally occurring. It's in lavender oil, bergamot oil, coriander, basil, thyme, and dozens of other plants, and exposure to air oxidizes it. It has a beautiful scent. And it had been quietly inflaming my skin for years, in products I was using because I thought they were safe.


The Accidental Experiment


Around the same time I was piecing this together, something else happened that confirmed it.


I have trichotillomania (which is just a big word that means I pull out my hair). At a certain point I'd pulled enough hair that I decided to shave my head and wait for it to grow back in evenly. For about a year, I used no shampoo, no conditioner, no hair products at all.


Without planning to, I'd removed an entire category of products from my routine, including all the botanical-heavy, naturally-scented hair care I'd been using.


About six months later, I noticed my skin wasn't as itchy and rashy as it used to be.


I hadn't added anything new. I'd just removed something I didn't realize was a problem.

Natural Ingredients That Commonly Trigger Reactions


This is the list I wish someone had handed me. These are all plant-derived or naturally occurring, and all of them are known contact allergens that show up regularly on patch test results:


  • Cinnamaldehyde (naturally occurring in cinnamon oil and some spice-forward botanicals)

  • Citrus aurantifolia (lime) peel powder

  • Citrus aurantium dulcis (orange) peel oil

  • Citrus extract (all)

  • Citrus limon (lemon) peel powder

  • Citral (naturally occurring in citrus and lemongrass)

  • Citronellol (naturally occurring in rose oil, geranium oil)

  • Coumarin (naturally occurring in tonka bean, sweet clover)

  • Eugenol (naturally occurring in clove, cinnamon, basil)

  • Farnesol (naturally occurring in linden blossom, chamomile, rose)

  • Fragrance/parfum (includes both synthetic and botanical fragrance compounds)

  • Geraniol (naturally occurring in rose oil, palmarosa, geranium)

  • Isoeugenol (naturally occurring in ylang ylang, clove)

  • Lanolin (naturally occurring in sheep's wool)

  • Linalool (naturally occurring in lavender, bergamot, coriander, basil, and many essential oils)

  • Limonene (naturally occurring in citrus oils)

  • Myroxylon balsamum / Balsam of Tolu (natural tree resin)

  • Myroxylon pereirae / Balsam of Peru (natural tree resin)

  • Oak Moss Absolute (natural lichen extract)

  • Propolis (natural bee product)


None of this means plants are bad, or that everyone will react to these. Most people don't. But if your skin tends to be reactive and you haven't looked at these specific ingredients, it's worth starting there.


What This Means for Sensitive Skin


If you've been struggling with reactive skin despite switching to "clean" or "natural" products, here's something to consider.


First, fragrance is still fragrance, even when it comes from a plant. Essential oils, botanical extracts, and natural aromatic compounds can all trigger contact reactions in sensitized skin. Phrases like "Made with essential oils" and "Made with botanicals" are not safety claims.


And because oxidation happens invisibly, on its own timeline, there's no way to eyeball whether the ingredient in your product has already turned. For skin that's already reactive, that's exactly why avoiding it altogether is the safer call. You can't manage a change you can't see.


It's not just me saying this. In 2023, the EU updated its cosmetic labeling rules to treat ingredients that oxidize into allergens (linalool being the obvious one) the same as the allergens themselves.


Also, contact allergy patch testing exists, and most people have never heard of it. If you've tried everything and your skin keeps reacting, ask your dermatologist about it. It can give you answers that elimination diets and label-reading can't.


And finally, what you remove can matter just as much as what you add. I didn't figure that out through research. I figured it out by accident, with a shaved head, six months later.


Why Rooted+Wilder Is Now Formulated Without Essential Oils


This is personal for me. I love plants. I believe in botanical medicine. I use herbs in my own practice and my own kitchen. I've also offered products with skin-benefitting essential oils, and customers loved them.


But I've let my inventory of essential oils run out, and all products I formulate going forward will be without essential oils. My core customer, those with sensitive, dry, or reactive skin, is exactly the population most likely to have undetected contact sensitivities. And because I know, from my own back, that "natural" and "safe for reactive skin" are two different things.


Every product in the Rooted+Wilder line is crafted to support the skin barrier. That's not a marketing claim. It's a formulation philosophy born from a lot of trial, error, and 80 chemicals on my back.


There's a formulation reason, too. Remember how linalool oxidizes into those more-reactive hydroperoxides once air gets to it? That clock doesn't start when the bottle lands on your shelf. It starts way earlier. An essential oil can oxidize in the supplier's warehouse, in transit, or in my lab before it ever goes into a batch. So "I only use fresh oils" isn't the clean guarantee it sounds like. By the time I could smell or test that something had turned, it'd already be in the jar. And I'd rather just not play that game with our skin.


If any of this sounds familiar — the years of trying, the products that were supposed to be gentle, the reactions you couldn't explain — I'd love to hear where you are with it. Leave a comment, or reach out directly. You're probably not as alone in this as you feel.



Frequently Asked Questions

Contact allergy patch testing (sometimes just called patch testing) is a dermatology procedure that identifies skin reactions caused by direct contact with specific chemicals. A dermatologist (or allergist) tapes small amounts of common allergens to your back — usually 80 or more substances — and checks the results at 48 and 72 hours. It's different from standard blood allergy testing, which looks for airborne or food triggers. Patch testing specifically identifies contact dermatitis, meaning reactions caused by things your skin is directly touching. If your skin keeps reacting to products you've already switched to "gentle" versions of, it's worth asking your dermatologist about it.

Linalool is a naturally occurring fragrance compound found in lavender, bergamot, basil, and a lot of other plants. Fresh, it's actually a weak allergen. But here's the part that surprised me: linalool reacts with air over time and becomes something called hydroperoxides (which is just the oxidized version of it), and those are far more likely to trigger a reaction than the fresh molecule.


That's why a product that felt fine the day you opened it can start bothering you months later, half-used in the back of a cabinet. So it's not really that lavender is out to get you. It's that "natural" ingredients change once air gets to them, and nobody puts that on the label. If your skin is reactive, it's worth checking your ingredient list, and noticing how old your open products are.

Yes. Several of the most common contact allergens are plant-derived, including linalool, limonene, cinnamaldehyde, balsam of Peru, and fragrance compounds from essential oils. The "natural" label has no regulated definition in the U.S. skincare industry, so it doesn't guarantee a product is fragrance-free, allergen-free, or tested for sensitive skin. A product being natural just means the ingredients originated from natural sources. That's not the same as safe for all skin types.

Contact dermatitis is a localized skin reaction triggered by direct contact with a specific substance, like a fragrance compound in a moisturizer. It's identified through patch testing. A standard allergy (the kind tested with blood tests or skin-prick tests) is a systemic immune response to things like pollen, pet dander, or food. You can have both, either, or neither. Many people with eczema or chronically reactive skin have contact sensitivities that show up on patch testing but wouldn't show up on a standard allergy panel, which is part of why they can be hard to catch.

If your skin tends to react, the ingredients most worth checking on labels are linalool, limonene, cinnamaldehyde, balsam of Peru, fragrance or parfum (in any form, synthetic or botanical), tea tree oil, and lavender oil. If you've already switched to "cleaner" products and your skin is still reacting, a dermatology patch test can give you actual answers rather than more guesswork.
