12, Castor oil induces laxation and uterus contraction via ricinoleic acid activating prostaglandin EP3 receptors. Pharmacology. 2012.
Note: castor oil is ~90% ricinoleic acid, a hydroxylated fatty acid that behaves very differently from the fatty acids skin evolved to work with. Ricinoleic acid activates prostaglandin receptors (EP3). prostaglandin signaling is a classic inflammation pathway. If someone’s follicles are acne-prone, anything that increases local irritation/inflammatory signaling can tip them into inflamed bumps.
