Science

Mechanism of Action

This extract leverages bioactive compounds, including honokiol and magnolol, to deliver comprehensive skin benefits. It effectively combats 'inflamm-aging' by inhibiting the inflammatory factor NF-κB, which in turn reduces pro-inflammatory cytokine production (e.g., TNF-α, IL-8). The extract neutralizes free radicals, safeguarding skin cells from oxidative stress and premature aging. It exhibits antimicrobial activity against bacteria such as Staphylococcus aureus and Propionibacterium acnes, making it beneficial for acne-prone skin. Furthermore, it inhibits collagenase and elastase enzymes, promoting skin firmness and elasticity. Magnolia Sieboldii Flower Extract also addresses hyperpigmentation by inhibiting DOPA auto-oxidation and melanin formation, supports skin barrier integrity through increased tight junction expression, and may regulate sebum production.

Key findings

  1. 01 Studies on Magnolia biondii flower extract (a related species) demonstrated attenuation of UVB-induced skin damage, including significant decreases in erythema and melanin, improved skin barrier function (reduced transepidermal water loss), and increased skin ITA° (indicating brightening) following pre-treatment for 3 days and post-treatment for 5 days.
  2. 02 Research on Magnolia officinalis liquid extract (another related species) indicated a reduction in neck wrinkle depth by 12.73% (mean) and 17.44% (maximum), alongside improvements in mean roughness (Ra) by 12.73%, root mean square roughness (Rq) by 10.16%, and maximum depth of roughness (Rmax) by 10.81%. It also boosted skin elasticity by 3.76% and subtly brightened skin tone by 0.76%.
