May Treat Dry Skin
Studies show that applying eucalyptus oil on your skin may improve dry skin by boosting its ceramide content. Ceramides are a type of fatty acid in the skin that plays a significant role in maintaining the barrier and retaining its moisture. People who have dry skin, dandruff, or skin disorders such as psoriasis and dermatitis may have low ceramide levels.
Studies show that topical eucalyptus leaf extract may help boost skin ceramide production, skin barrier protection, and water-holding capacity. It contains a compound known as macro carpal A, which appears to boost ceramide production. A study on 34 people using a scalp lotion containing eucalyptus leaf extract and synthetic ceramide showed that they experienced significant reduction in scalp redness, scaliness, dryness, and itchiness. This is why many skin and hair products contain eucalyptus leaf extract.
