CERASUS YOUKOU FLOWER POWDER.

Valuable CAS - / SKIN CONDITIONING

A refined botanical powder derived from the Japanese Youkou Sakura, known for its high concentration of rejuvenating polyphenols. This precision ingredient targets the structural integrity of the dermal matrix while providing potent defense against oxidative stress.

Antioxidant Skin Conditioning Anti-aging Brightening

Science

This ingredient operates through a triple-action pathway: it neutralizes free radicals via flavonoid-rich antioxidant activity, prevents the enzymatic breakdown of collagen and elastin by inhibiting MMP-2 and elastase, and utilizes phyto-compounds to modulate melanogenesis for improved skin clarity.

Key findings

  1. 01 In vitro trials confirmed that concentrations as low as 0.1% provide antioxidant protection comparable to 0.1% Catechin.
  2. 02 Studies at 0.5% concentration demonstrated significant inhibition of elastase, protecting the skin's structural proteins from degradation.
  3. 03 Clinical assays at 0.25% to 0.5% showed effective suppression of melanin production in B16 melanoma cells.
