What is "ROSMARINUS OFFICINALIS LEAF OIL" and what does it do?

Role: EMOLLIENT

Family: Rosemary essential oil

Comedogenic index: 0

Rosmarinus officinalis is a dense, bushy perennial shrub in the Lamiaceae family.

Although rosemary oil is appreciated for its fragrance, it contains volatile compounds, including camphor, which can be irritating to the skin. These substances, while giving the oil its characteristic aroma, can cause sensitivity reactions when applied to the skin.

Precautions for use
Do not use during pregnancy or breastfeeding, or on children under 6 or people with sensitive skin.

Rosemary essential oil is highly prized for skin care, particularly for combination and oily skin. It is recognized for its astringent and purifying properties, helping to regulate sebum secretion and purify the epidermis. Thanks to its action, skin imperfections are reduced and pores tightened.

Native to Provence in France, this shrub can reach a height of 2 meters at maturity. It is also nicknamed "Rose Marine", due to its preference for maritime environments. The origin of its name, rosemary, is Latin and means "dew of the sea". Historically, in ancient Greece, it was used as a remedy for digestive ailments, as well as to improve memory and concentration. In ancient Egypt, its use seems to have been more religious, as evidenced by the presence of rosemary sprigs in tombs. In the Middle Ages, distillation of this plant produced a perfumed extract.

Production of camphor rosemary essential oil
Camphor rosemary essential oil is produced by hydrodistillation of the plant's flowering branches. The process involves heating a mixture of water and twigs to vaporize the volatile components, which are then collected after condensation. This technique produces two extracts: the hydrolat and the essential oil, with a yield of less than 5%.
The essential oil obtained is a clear, mobile liquid, pale yellow to yellowish-green in color, with a fresh, rustic, slightly camphorated fragrance. It contains mainly ketones (around 30% of camphor), monoterpenes (around 17% of alpha-pinene, 9 to 20% of camphene), monoterpenols and sesquiterpenes.
