Science
Mechanism of Action
This botanical extract operates through several mechanisms to benefit the skin. It exhibits potent antibacterial and antifungal properties, effectively combating microorganisms implicated in conditions like acne and other cutaneous infections. The extract also provides significant anti-inflammatory effects, helping to calm irritation associated with concerns such as acne, eczema, and dermatitis. Functioning as a powerful antioxidant, it protects the skin from oxidative stress caused by environmental aggressors, thereby aiding in the prevention of premature aging. Additionally, it contributes to oil balancing by regulating sebum production, which is particularly beneficial for oily and acne-prone skin types, and supports skin healing processes. It has also been shown to promote melanogenesis via the upregulation of TRP-1 protein expression.
