Is Ricinus Communis (Castor) Seed Oil a Good Ingredient?
Good, because it's a rich, occlusive emollient that softens skin and helps reduce transepidermal water loss, with a long track record and good stability that justify the rating. Some users, especially those who are acne-prone, may find it heavy or pore-congesting despite its generally low comedogenic rating, which is enough to keep it from Great.
