Science

Mechanism of Action

This extract's efficacy is attributed to its rich composition of active compounds. It contains powerful antioxidants such as Vitamin C and flavonoids, including hesperidoside and naringoside, which neutralize free radicals to combat premature aging and enhance skin radiance. Terpenes like linalool and limonene contribute to its characteristic fragrance and offer anti-inflammatory benefits, helping to calm redness and irritation. Esters, sesquiterpenols, and sesquiterpenes further support its soothing actions. Additionally, it exhibits antimicrobial properties against certain bacteria like *Staphylococcus aureus*, may reduce melanin formation through anti-tyrosinase activity, and can regulate sebum production for oil control on the scalp.
