🧪 INTRO – When Science Meets Skincare
Herbal-infused oils have become one of my favorite ways to connect with plants—slowly, intentionally, and with a touch of science. I still remember the first time I made my own herbal infused oil. It was summer, everything smelled like sun-warmed rosemary, and I had absolutely no idea what I was doing. Spoiler alert: I forgot to dry the herbs properly, and the whole jar went funky in a week. But even then—there was something magical about watching those natural ingredients slowly transform in the sun.
Back in university, I spent hours in ecology labs, pressing leaves between paper, labeling wildflowers, and memorizing Latin names that felt like spells. I was fascinated by the way nature worked in quiet, invisible rhythms. In university, I pressed herbs into pages. Now, I press them into oils.
Today, herbal-infused oils are at the heart of my natural skincare rituals. They’re simple, soulful, and deeply connected to the seasons. There’s something incredibly grounding about making skincare with your own hands—feeling the texture of dried chamomile, pouring golden oils, and waiting patiently as the herbs and oils work their slow magic.
This post is part story, part science. I’ll walk you through what herbal oil infusion is, how my botanical background shaped how I work with plants, and how you can start your own ritual—no lab coat needed. 🌿
What Is Herbal Oil Infusion (and Why I Love It So Much)
If you’ve ever picked a flower and instinctively brought it to your nose, you already understand the heart of herbal oil infusion. It’s about capturing that fleeting moment—when scent, warmth, and plant energy meet—and preserving it inside an oil that your skin will absolutely adore.
An herb-infused oil is exactly what it sounds like: oil steeped with dried herbs to draw out their natural properties. Some people call it botanical maceration, and others just call it magic. But technically, there are a few different infusion methods, each with its own rhythm and charm.
One of my favorite approaches is the cold infusion method. It’s the slowest but also the most intuitive. I place dried herbs—like chamomile, calendula, or rosemary—into a clean glass jar, cover them completely with oil, seal them tight, and let the sun do the rest. I leave it in direct sunlight, shake it gently every day, and wait at least 3 weeks (sometimes longer, depending on the season or—let’s be honest—my attention span). The result? A golden, herb-rich oil that smells like late summer.
If I’m in a hurry or working with tougher herbs, I use the double boiler method. That means gently warming the herbs and oil over low heat—just enough to encourage the extraction without cooking anything. It’s hands-on, cozy, and ideal when you’re craving a more immediate batch of skin-loving goodness.
No matter which method you choose—sun-warmed patience or gentle heat—herbal oil infusion is one of the simplest and most powerful ways to incorporate the wisdom of herbs and oils into your skincare. It’s where tradition meets intuition, and skincare becomes something deeper than routine. It becomes a ritual.
How My Botanical Background Changed the Way I Infuse Herbs
Studying ecology didn’t just teach me about plant systems and Latin names—it taught me how to observe. To notice subtle signs. To understand that a plant’s vitality starts long before we harvest it. And that’s exactly what shifted the way I approach herb-infused oils.
I don’t just toss herbs into a jar and hope for the best anymore. I start with the plant itself—where it grows, how it feels, when it’s at its peak. For example, I always harvest St. John’s Wort on a dry, sunny day around midsummer, when its yellow flowers almost seem to glow. That’s when its herbal properties are strongest, and the resulting oil turns the most beautiful deep red.
If you’re curious about working with this plant, I wrote an entire post on how to make St. John’s Wort oil from the fresh herb — it’s a summer ritual I look forward to every year.
On the other hand, I like to pick lavender flowers early in the morning, just as the sun hits the petals but before the volatile oils start to fade. Small things like this—timing, weather, energy—make a big difference in the quality of the final infusion.
Over time, I’ve learned that how you infuse herbs matters just as much as what you infuse. The method you choose will shape the oil’s potency, feel, and shelf life.
🌞 Cold Infusion Method
My favorite technique is cold infusion. I fill a clean jar with gently dried herbs, pour in a nourishing carrier oil, and let the sun slowly draw out the plant’s essence over three weeks. There’s something beautiful about watching the oil change color in a sunlit window—it’s like the plant is still alive in there, just quieter. This method is especially gentle and perfect for delicate herbs like chamomile or rose.
🔥 Double Boiler Method
When I want to speed things up, I use the double boiler method. It’s simple: Place the herbs and oil in a heat-safe container, warm it gently over low heat, and stir occasionally—just enough to encourage extraction—never to fry or force. This method works beautifully with tougher botanicals like roots or thicker leaves, and it’s great when you need your herb-infused oil a little sooner.
Each plant has its own rhythm and its own relationship with oil. St. John’s Wort, with its fiery red pigment. Lavender, soft, and floral, ready to calm. Yarrow, deep, and slightly wild. You learn by listening. By observing. By trying. And above all, by honoring the slow work of nature—with clean tools, steady hands, and a heart tuned to the seasons.
🌼 My Seasonal Herbal Oil Infusion Ritual
Working with the seasons keeps me grounded. Every few months, I pause, look at what’s growing around me, and ask: What does my skin need now? The answer almost always begins with the plants.
Over the years, I’ve found my favorite herbs to infuse and shift gently with the rhythm of nature. And honestly, that’s the beauty of it—no two years are exactly the same.
🌱 Spring: Awakening the Skin
After a long winter, I reach for gentle, mineral-rich herbs that help revive dull skin. Plantain leaf is one of my spring staples—soothing, repairing, and often overlooked. I usually pair it with violet flowers, which bring moisture and softness, especially to dry, wind-chapped cheeks.
Both go into a jar in a sunny window for a few weeks, slowly releasing their goodness into oil as everything outside blooms.
☀️ Summer: Solar-Powered Magic
This is my favorite season for infusions. The sun is strong, the herbs are vibrant, and the energy is all about abundance.
St. John’s Wort, as I I walk through the full process of how to make St. John’s Wort oil from fresh flowers—from foraging to infusion, is a midsummer ritual for me. I also love working with chamomile, especially when I want something calming and golden.
Because the sun is so powerful, summer is ideal for making heat-infused oils naturally—just by placing a jar outside, letting that solar warmth do its thing. It feels like the plant and the sun are co-creating something magical.
🍂 Autumn: Repair and Reset
In early autumn, I start gathering calendula and rosemary—two herbs that prepare the skin for colder months ahead. Calendula brings gentle repair and softness, while rosemary boosts circulation and gives the oil a grounding scent.
If the days are still warm enough, I’ll do a sun infusion. If not, I turn to a gentle heat-infused oil using the double boiler method—especially if I’m blending tougher herbs or roots.
❄️ Winter: Slowness and Stored Sunshine
In winter, I mostly rely on dried blends from earlier in the year. Think lavender, rose, and yarrow—herbs that remind me of warmer days. This is the season for introspective formulas: oils that comfort, protect, and restore.
Sometimes, I’ll make small batches from dried herbs in the pantry, adding a few warming spices like cinnamon or clove. Even in the quiet, cold months, herbal oil infusion feels like a way to keep the light going.
Each season brings its own invitation. Some herbs arrive quietly, others burst into bloom. But they all offer something—a scent, a sensation, a softness—that’s worth bottling. 🌿
🧺 Tips for Readers Who Want to Try Herbal Oil Infusion
So, you’re ready to start your own herbal oil infusions? Amazing. Before you reach for the jar and the flowers, here are a few things I’ve learned—sometimes the easy way, sometimes… not so much.
🌼 Start With Quality Herbs (and Intention)
The infusion process starts long before the oil touches your skin. What matters most is the quality of your materials.
- Use herbs that are vibrant, aromatic, and well-dried.
- Flowers should be dry to the touch but not brittle. If you want to go a step further, lightly mist them with alcohol—just enough to soften the plant’s cell walls. This technique, often called an alcohol intermediary, helps unlock and extract deeper herbal properties once the herbs meet the oil.
- Chop or crush the herbs gently—using a mortar and pestle if you have one. This exposes more surface area and helps draw out the good stuff.
🌿 Choose the Right Oil (And the Right Jar)
Use high-quality, cold-pressed carrier oils suited to your skin’s needs—like jojoba, sweet almond, or olive oil. And always work with herbs in a clean, dry glass jar. Hygiene is key here. You’re creating something delicate and powerful, so treat it like you would food for your skin (because, honestly, that’s what it is).
Not sure which oil to choose for your next infusion? I put together a full botanical oil guide for skincare that breaks down the benefits of jojoba, grapeseed, avocado oil, and more—so you can match the oil to your skin and your herbs.
Pour the oil over your herbs until they’re fully submerged. If any part of the plant is exposed to air, it can cause oxidation—or worse, mold.
🌞 Let the Infusion Process Do Its Thing
Whether you’re sun-infusing over 3 weeks or gently warming over a double boiler, check the oil daily in the beginning. The herbs may absorb some of the oil, so it’s important to top up if needed. This ensures the plant material stays safely covered.
🫙 When It’s Ready, Strain Carefully
Once your oil has finished infusing, it’s time to strain the herbs. I use an unbleached coffee filter or a very fine muslin cloth to catch any herb sediment. Take your time with this part—it’s oddly satisfying to watch the golden oil flow through.
🌑 Store With Care and Label With Love
Transfer your infused oil into a dark, clean brown glass bottle. This helps protect it from light and extends its shelf life. Oh—and label everything. I mean it. I’ve forgotten what was what more times than I’d like to admit. Write down:
- What herb did you use
- What oil did you infuse in
- The date you made it
Future you will thank you.
🌼 Bonus tip: Add a few drops of vitamin E oil to your infusion. It is a natural antioxidant and can help prevent your oil from going rancid or working with more delicate oils.
⚠️ Know When to Let Go
As much as we’d love every infusion to turn out perfectly, sometimes things just… go off. Literally.
If your oil starts to smell sour, musty, or just off, it may have started to go rancid or grow mold. That’s a clear sign it’s time to let it go. Rancid oils can irritate the skin, and mold means bacteria have joined the party—and that’s a party your skin definitely didn’t RSVP to.
This can happen if the herbs weren’t fully dried if too much moisture got into the jar, or if the container wasn’t sterile. Another reason I love the alcohol intermediary method is that it adds an extra layer of protection—helping to prevent spoilage while pulling out even more goodness from the herbs.
Bottom line? If your infusion smells bad, looks strange, or makes your skin feel itchy or warm in a weird way—don’t use it. Trust your senses. Skin irritations are never worth it.
✨ Skincare Is Slow Science with Soul – my herbal infused oils
Making herbal oil infusions isn’t just about glowing skin—it’s about creating something with presence, patience, and purpose. It’s the kind of process that slows you down in the best possible way. You touch the plants, you smell the oil, you pay attention to subtle shifts. And somewhere in that ritual, something softens—on your skin and inside you.
And here’s the beautiful part: this isn’t just folk wisdom anymore. A 2024 study published in Plants (Basel) confirmed that when organic herbs are gently macerated in oils—especially infused olive oil—they release a wide range of beneficial compounds with antioxidant and anti-inflammatory properties that directly support skin health (source).
So yes, this is slow skincare—but it’s also backed by science.
And how do you use your infusions? That’s entirely up to you. Some become massage oils for tired legs. Others find their way into nourishing lip balms or nightly cleansing rituals. With the right glass bottles, a good label, and a little personal preference, your oil becomes a story—a collaboration between you and the plant.
So take your time. Press flowers into jars. Watch oils turn golden. Let your skincare be more than just a routine. Let it be a relationship.
