Rosemary Essential Oil: The Multi-Functional Skincare Secret of Natural Plants

Rosemary essential oil is extracted from the fresh stems and leaves of the rosemary plant, which belongs to the Lamiaceae family. Thanks to its antibacterial, antioxidant, and circulation-promoting properties, it has become a ‘jack-of-all-trades’ in the cosmetics ingredient industry. Extracted using steam distillation, rosemary essential oil retains active components such as 1,8-cineole (40%-55%), camphor, and rosmarinic acid, which confer its powerful skincare efficacy and aromatic therapeutic value.

Core efficacy analysis

1. Scalp health management: 1,8-cineole inhibits Malassezia fungi by 89%. Adding 1%-2% rosemary essential oil to shampoo formulations can effectively reduce dandruff production while stimulating blood circulation in hair follicles. Clinical data shows that continuous use for three months increases hair density by 27%;

2. Antioxidant Protection Shield: The rosemary acid it contains has twice the free radical scavenging capacity of vitamin E. When added to serums (at a 0.5% concentration), it can protect against oxidative damage caused by UV rays and pollution, with skin radiance improving by 32%;
