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.
Nearly 90% of castor oil is one fatty acid called ricinoleic acid,¹ and ricinoleic acid has a secret. A kink in its chain, with a tiny hook at the bend that almost no other plant oil has.
That hook changes how castor oil behaves in your skin barrier, and it helps carry other ingredients through.¹
Once it’s past that threshold, ricinoleic acid starts to calm swelling. Your body signals swelling and soreness with a messenger called substance P, and in research, ricinoleic acid brought it down.² Consistency is what made it work.
And that’s why castor oil is a ritual.
