Science & Benefits

Castanea Crenata (Chestnut) Shell Extract is exceptionally rich in ellagic acid and condensed tannins. In skincare, it serves as a dual-action active: the tannins act as a mild, non-stinging astringent that temporarily constricts the pore opening, while its polysaccharides function as humectants. For acne-prone individuals, it is highly effective at refining skin texture and reducing the visual appearance of 'stretched' pores without the drying effect of alcohol. It is entirely non-comedogenic and provides significant antioxidant protection, preventing the sebum oxidation that leads to blackheads.
