Derived from the common basil plant, Ocimum Basilicum Leaf Extract is a multi-functional botanical ingredient recognized for its potent antioxidant, anti-inflammatory, and antimicrobial properties. It actively protects the skin from environmental stressors while addressing concerns like redness, blemishes, and premature aging, promoting a balanced and resilient complexion.

Science

Ocimum Basilicum Leaf Extract exerts its effects through a rich profile of bioactive compounds, including flavonoids, phenolic acids (such as rosmarinic, ferulic, and caffeic acids), and terpenes. These compounds neutralize reactive oxygen species (ROS) and reactive nitrogen species (RNS), mitigating oxidative stress and safeguarding cellular integrity. Its anti-inflammatory action involves modulating key pathways like NF-κB, MAPK, and COX-LOX, thereby reducing pro-inflammatory cytokines and associated redness and swelling. Furthermore, its antimicrobial capabilities disrupt microbial cell membranes and inhibit biofilm formation, effectively targeting acne-causing bacteria like Propionibacterium acnes. Beyond these primary actions, the extract also contributes to skin hydration, helps regulate sebum production, and assists in refining pores.

Serum formulations containing Ocimum Basilicum Leaf Extract maintain good physical stability within a slightly acidic pH range (approximately 4.66 to 4.98). Optimal pH for broader stability is not comprehensively defined, but stability within this narrow acidic range has been observed.


Safety

CIR Status
Not reviewed
Sensitization risk Low

Ocimum Basilicum Leaf Extract is generally recognized as safe for topical cosmetic use. It is important to differentiate this extract from Ocimum basilicum essential oil, which contains volatile compounds like linalool and eugenol known for their sensitizing potential. While the extract contains some tannins that can have a constricting effect on surface cells, its overall irritancy profile is low, and a 3% concentration in microemulsion has been shown to be well-tolerated. Individuals with sensitivities to botanical ingredients should conduct a patch test prior to widespread application.
