The Science of Castor Oil

Most women have tried castor oil. Few understand why it actually works.
That answer changes everything you know about how to use it.

What Makes Castor Oil Different

One of the best kept secrets in skincare is how little of what you apply actually makes it through your skin. Your skin has a threshold, a size limit for molecules, and most of what you put on stays right on the surface.

And that includes most oils. Argan, rosehip, coconut. They soften your skin and lock in moisture, but they don't go much further.

Castor oil is different. Not just in how much gets absorbed, but in how it behaves once it hits your skin.

Here's why.

Fatty acids are the building blocks of oils, the individual molecules that make up what you put on your skin, and most are straight chains. When those straight chains meet your skin, they line up, stack on top of each other, and stay flat on the surface.¹

Nearly 90% of castor oil is one fatty acid called ricinoleic acid,¹ and ricinoleic acid has a secret. A kink in its chain.

That kink means it can't line up and stack like the others, so instead of stopping at the surface it moves more fluidly within the skin barrier, into the layers where circulation and fluid buildup begin to shape what you see on the surface.²

Once ricinoleic acid gets past that threshold, it works with a receptor in your body called EP3, one of your body's own regulators of blood flow and fluid movement.³ Your body does the rest.

And circulation is where all castor oil rituals begin.

LYMPHATIC SYSTEM 

Face, neck and chest

Your face sits on top of more than 300 lymph nodes and vessels,⁴ their job is to drain fluid, clear waste, and keep definition in your face. But they have no pump. They move only when blood circulation does.

Age, hormones, and daily stress slow that down and when it does, lymph stagnates, fluid builds, and skin loses support. That's where puffiness and fine lines settle in.

Castor oil supports your natural blood circulation in the tissue beneath the skin for visibly less puffiness, softer looking fine lines, and a healthy plump glow.

DIGESTION AND LIVER 

Navel and Abdomen

Your liver and digestive system work in a loop, the liver processes hormones and waste and digestion moves it out. When blood circulation and lymphatic flow slow down, that loop lags.

Waste lingers, hormones hang around, and you feel it as bloat, heaviness, and fullness you can't shake.

Castor oil supports blood circulation and lymphatic flow beneath the skin so your body can keep that loop moving for less bloat, reduced heaviness, and supported digestive comfort.

NERVOUS SYSTEM 

Pulse points, chest and belly

You're exhausted but your body won't slow down. That's your nervous system stuck in its activated state, still responding to a day that's already over.

Your vagus nerve is your body's built-in pathway from stressed to calm,⁵ running from your brain through your neck, chest, and belly. Pulse points, the belly button, and the chest are where it runs closest to the surface and where it's most accessible. Chronic stress, hormonal shifts, and age all reduce how well that pathway works, making the shift harder to reach.⁶˒⁷

Castor oil supports blood circulation in those areas, helping your body find its way back to calm.

Hormone Balance

Full Body

Your lymphatic system, your liver, digestion, and your nervous system all play a role in how your hormones are processed, cleared, and regulated. When one slows down, you feel it. When all three slow down, it shows up everywhere.

The Trifecta supports all three. Same castor oil base, each botanical directed at a different system.

The Ultimate Carrier Oil 

Ricinoleic acid gives castor oil another superpower. It's not only able to make its way through your skin, it takes whatever is mixed with it along for the ride. Meet the botanicals we blend with it, each one chosen for intentional, targeted support. 

Boswellia Carterii

Frankincense carterii works with castor oil to reach beneath the surface, where puffiness begins. It supports circulation, eases tension, and visibly de-puffs so skin looks more rested.

Boswellia serrata

Frankincense serrata is one of the most studied botanicals for visible skin renewal, supporting cell turnover, softening fine lines, and helping skin look clearer and more even.

Lavandula angustifolia

Lavender eases that wired feeling, supports deeper sleep, and helps your body find its way back to calm. One of the few botanicals with a documented effect on cortisol.⁸
