Ingredient review
Marjoram Leaf Oil
INCI: ORIGANUM MAJORANA LEAF OIL
Marjoram leaf oil adds a warm herbal scent and may offer mild soothing benefits, but it can be irritating for sensitive skin.
In plain English
Marjoram leaf oil is a natural essential oil pressed from the leaves of the sweet marjoram plant. In skincare, it is mainly used to give products a pleasant herbal fragrance. Some people find it calming on the skin, but because it is a concentrated oil, it can cause redness or stinging if used in high amounts or on sensitive skin. It is not a moisturizer or active treatment, so think of it as a scent booster with a possible gentle soothing side effect.

What it is
Marjoram leaf oil is a volatile essential oil extracted from the leaves of Origanum majorana, a herb in the mint family. It contains compounds like terpinene and sabinene that give it its characteristic scent.
