Here's something most people don't realize about essential oils: they don't just sit on the surface of your skin.
When you apply an essential oil to your skin — properly diluted, the way I always do — it doesn't stay on top. It enters. The compounds in essential oils are small enough and fat-soluble enough to cross the stratum corneum, the outermost layer of your skin, and make their way into the deeper layers. From there, some of those compounds enter the microcirculation and move into the bloodstream. That's not a side effect. That's intentional delivery.
What this means for your skin.
When an essential oil reaches the dermis, it's arriving with its full therapeutic chemistry intact. It's not filtered through digestion, it's not metabolized by the liver first, it's not broken down before it gets where it needs to go. It arrives through the skin directly, at the site where you need it — and then a portion of it continues into systemic circulation, which means it can have deeper effects on inflammation, nervous system regulation, and cellular function beyond just the application site.
This is why topical application of essential oils can influence things like cortisol levels, immune response, and lymphatic activity — because the compounds actually get into the body and do something once they're there. They're not just aromatic. They're pharmacologically active when they need to be.
The science behind it.
The rate at which an essential oil compound penetrates skin depends on several things — molecular size, lipophilicity, the condition of the skin barrier, and the vehicle it's delivered in. Essential oils are lipophilic by nature, which means they integrate well with the lipids in your skin cells. This is actually why they work so well in skin formulations — they're not fighting the skin's natural structure, they're working with it.
This is also why I formulate the way I do. The oils I choose for a product aren't just selected for their scent or their aromatherapeutic effect — they're selected for their ability to penetrate, deliver, and integrate with skin tissue. The dilution, the carrier, the combination of oils — all of it is designed around optimizing that delivery.
The bottom line.
Essential oils are not surface treatments. They are active compounds that your skin welcomes, absorbs, and distributes — and that's exactly what makes them remarkable as a tool in skincare. When I use them in the treatment room or in our formulations, I'm not just creating a nice smell. I'm delivering something that actually gets into your skin and does something once it's there.
That's worth knowing, especially if you've been told that natural skincare is just about feeling good rather than actually working.
