Can evening primrose oil reduce sebum secretion?

Generally, whether evening primrose oil can reduce sebum secretion depends on the method of use and individual skin conditions. The detailed analysis is as follows:

If the skin exhibits mild oiliness caused by slight damage to the skin barrier or imbalanced water-oil levels leading to abnormal sebum production, taking evening primrose oil orally or applying lightweight skincare products containing evening primrose oil locally—combined with gentle cleansing and proper moisturizing—may assist in reducing sebum secretion. This approach helps regulate skin condition and correct water-oil imbalance, potentially leading to more stable sebum production over time.

However, if the skin is severely oily and the excessive sebum is primarily due to genetic factors, hormonal imbalances, or a high-sugar diet, using evening primrose oil alone is usually insufficient to effectively control sebum production. In such cases, the regulatory effect of evening primrose oil cannot address the underlying causes of oiliness. Moreover, if the skincare product used has a heavy texture, it might increase the burden on the skin and even worsen oil secretion, failing to achieve the desired reduction in sebum.

Prior to using evening primrose oil, individuals should confirm they have no history of allergies and follow recommended dosages when taking it orally to avoid gastrointestinal discomfort from overuse. For topical application, perform a patch test behind the ear first to prevent allergic reactions such as redness or itching. If there is no improvement in sebum secretion after prolonged use, or if skin irritation occurs, discontinue use and consult a healthcare professional. Additionally, reducing sebum secretion requires a comprehensive approach including a healthy diet and regular sleep patterns; it should not rely solely on evening primrose oil.
