May treat dry skin
Eucalyptus can help dry skin by boosting its ceramide concentration. Ceramides are a kind of fatty acid found in your skin that is responsible for its barrier and moisture retention. Ceramide levels are often lower in those who have dry skin, dandruff, or skin illnesses such as dermatitis and psoriasis. Topical eucalyptus leaf extract has been shown to increase ceramide formation, hydration retention, and skin barrier protection. It includes macrocarpa A, a chemical that appears to increase ceramide synthesis.
A scalp lotion comprising eucalyptus leaf extract and synthetic ceramide dramatically reduced scalp redness, itching, dryness, and scaliness in 34-person research. As a result, the eucalyptus leaf extract is used in many hair and skin care products.
