Evening primrose oil is derived from the seeds of Oenothera biennis and is rich in gamma-linolenic acid (GLA) and linoleic acid, fatty acids that support skin barrier function and may help reduce inflammation. It is used topically as a moisturizing and conditioning ingredient and is sometimes studied for atopic dermatitis and dry skin.

Acneiform breakouts or clogged pores | Rare | Possible in those prone to comedones due to the oil's emollient nature. |
