Is Castor Oil Good for Skin?

Castor oil has a long history of traditional use for dry, rough or sensitive skin, thanks to its naturally high fatty acid content. Its rich, emollient texture helps soften and hydrate. Some studies suggest castor oil may support skin hydration by helping maintain the skin’s natural barrier, although more research is needed.
