CORNUS WALTERI LEAF EXTRACT.

Valuable CAS - / SKIN CONDITIONING

A sophisticated botanical bioactive derived from Walter's Dogwood, specifically utilized for its high concentration of anti-inflammatory and barrier-strengthening compounds. It serves as a multi-pathway defender against environmental stressors, bridging the gap between traditional herbal wisdom and modern precision skincare.

Antioxidant Anti-inflammatory Skin-Conditioning Agent Barrier Repair UVB-Protection Support

Science

This extract modulates the skin's inflammatory response by suppressing the phosphorylation of NF-κB and reducing the production of nitric oxide and pro-inflammatory chemokines such as TARC and MDC. It simultaneously reinforces the physical skin barrier by upregulating filaggrin expression and provides a photoprotective effect by neutralizing oxidative stress induced by UVB radiation.

Key findings

  1. 01 Demonstrated significant reduction in AD-related chemokines (eotaxin-3, TARC, MDC) and upregulation of filaggrin mRNA in human keratinocyte (HaCaT) cell lines.
  2. 02 Isolated compounds like lupeol and betulinic acid showed significant inhibition of eotaxin-3 levels at concentrations up to 10 µM.
  3. 03 Proven protective effects against UVB-induced photoaging in human reconstituted skin models.

Transparency

Commonly dusted

Due to its complex extraction process and status as a 'botanical extract,' this ingredient is frequently included at negligible concentrations (below 0.1%) to satisfy marketing claims without providing functional anti-inflammatory or barrier-repair benefits.
