Citrus aurantium amara
When used in skincare, petitgrain oil prevents over-production of sebum and also tones the skin. It's particularly beneficial for troubled skin and scalps.
Petitgrain oil is a pale yellow to clear liquid with a fresh, woody aroma. Its sweet smell is said to have an uplifting effect on the mind and it's often used interchangeably with orange blossom and neroli to calm the mind.
