Science
Mechanism of Action
It functions by suppressing pro-inflammatory signaling molecules such as TNF-α and various interleukins (IL-4, IL-6, IL-8) while inhibiting the NF-κB pathway. Furthermore, it accelerates physical barrier recovery by stimulating keratinocyte migration through the activation of Rho GTPases and stabilizing essential mRNA markers for wound healing.

Dusting Analysis
While birch extract is often featured in marketing for 'birch water' products, it is frequently used at negligible levels (<0.1%) for label claims. Meaningful barrier repair and antioxidant benefits typically require higher inclusion rates, ideally above 1-2%.
