Science
Mechanism of Action
The ingredient operates by enhancing skin hydration through its humectant and emollient properties, contributing to a healthier skin barrier. Mechanistically, insights from studies on Caragana sinica suggest it provides antioxidant protection by impeding oxygen-promoted reactions, thereby safeguarding the skin from external aggressors. It is believed to support skin repair and reduce signs of aging by stimulating keratinocyte proliferation and migration, augmenting collagen type I and IV synthesis, and upregulating hyaluronic acid and hyaluronic acid synthase-2 levels. Furthermore, its potential anti-inflammatory action, demonstrated by a reduction in pro-inflammatory cytokines such as TNF-α, interferon-γ, IL-6, and MCP-1, may help alleviate irritation and ameliorate skin lesions. The extract also shows promise in inhibiting tyrosinase activity and suppressing melanin production, indicating a mechanism for achieving skin brightening and a more even tone.

Safety Profile
This ingredient is listed in the European Commission's CosIng database, permitting its use in cosmetic formulations within the EU. However, a specific safety assessment by the Cosmetic Ingredient Review (CIR) Expert Panel or the Scientific Committee on Consumer Safety (SCCS) for this exact fermented ingredient has not been published. While Caragana species are found in FDA listings and general 'Yeast-Derived Ingredients' have undergone CIR review, these evaluations do not directly apply to the specific safety profile of this ferment extract filtrate.
