Cold-pressed castor oil is a thick, pale-yellow plant oil derived from the seeds of Ricinus communis. Its standout constituent is ricinoleic acid, a hydroxyl fatty acid that makes up the majority of castor oil's fatty acid profile and is studied for its ability to support skin hydration and soothe surface-level inflammation. The cold-pressing method preserves these fatty acids without the degradation that heat extraction can cause, making it a reasonable choice when ingredient integrity matters.
This is a versatile single-ingredient oil. It suits people looking for a straightforward, unfussy topical for dry or rough skin - elbows, heels, cuticles - as well as those who use it as part of a hair and scalp routine. It is occlusively heavy, which means it seals moisture in well but is best used in targeted applications or diluted for larger surface areas rather than worn alone on the face by those prone to congestion.
KIKI HEALTH produces a range of single-ingredient nutritional and topical products. Their cold-pressed castor oil is unrefined, keeping the fatty acid profile as close to the native seed composition as possible. For those who prefer a minimal-ingredient approach - one ingredient, clearly sourced - this fits that brief without complication.
