CASTANEA CRENATA FLOWER EXTRACT.

Valuable CAS - / ANTIMICROBIAL, ANTIOXIDANT, SKIN CONDITIONING

A high-precision botanical extract derived from the Japanese Chestnut flower, engineered to reset the skin’s internal recycling mechanisms. It functions as a potent 'longevity' active that targets cellular senescence to maintain tissue structural integrity.

Autophagy Inducer Antioxidant Pore Refiner Anti-Senescence Agent

Science

Operates as a natural autophagy activator by inhibiting EP300 acetyltransferase and stimulating the AMPK pathway. This triggers mitophagy—the clearance of damaged mitochondria—and utilizes bioactive polyamines like spermidine to restore cellular homeostasis and neutralize oxidative stress.

Key findings

  1. 01 In vitro analysis demonstrates an 80% increase in LC3II autophagic flux and a 32.78% reduction in senescence-associated β-galactosidase activity at concentrations of 50-100 μg/mL.
  2. 02 Human clinical trials of topical formulations indicate significant reductions in sebum production and visible pore diameter.
  3. 03 In vivo data suggests a 25-60% improvement in tissue functional markers and an 18% increase in structural weight through mitochondrial protection.

Because this extract is bio-active at extremely low concentrations (as low as 0.005%), many brands include it at 'label-only' levels below the threshold of efficacy to claim anti-aging benefits without providing the necessary concentration for autophagic activation.


The Formula

Solubility
Water
Optimal pH 4 – 6.5
0 7 14

Stability

Highly stable in aqueous systems but sensitive to photo-oxidation. Phenolic acids may degrade and cause color shifts if exposed to UV light or temperatures exceeding standard room conditions.

Synergies

  • Niacinamide
  • Hyaluronic Acid
  • Spermidine

Conflicts

  • Strong oxidizing agents
  • Alkaline environments (pH > 8.0)

Safety

CIR Status
Not reviewed
Pregnancy
Safe
Sensitization risk Low

While generally recognized as safe, individuals with known chestnut or tree nut allergies should perform a patch test due to potential cross-reactivity with botanical polyamines.
