Ingredient review
Citrus Keraji Fruit Oil
INCI: CITRUS KERAJI FRUIT OIL
A fragrant citrus oil that adds a fresh scent and mild antioxidant benefits, but may cause irritation in sensitive skin.
In plain English
Citrus Keraji Fruit Oil is a natural oil pressed from the peel of a rare Japanese mandarin called Keraji. It smells bright and citrusy, and it contains natural antioxidants that can help protect the skin from environmental stress. However, like many citrus oils, it contains compounds that can make skin more sensitive to sunlight, so it's best used in products that are rinsed off or that include proper sun protection.
