Mechanism of Action
This extract functions as a skin conditioning agent, humectant, antimicrobial, antioxidant, and skin protectant. Its rich profile of polyphenolic compounds, including carnosic acid and rosmarinic acid, provides robust antioxidant and anti-inflammatory benefits. It actively suppresses microbial growth and replication, mitigates oxidative stress to prevent cellular damage, and forms a protective film on the skin's surface.
