This short-chain poly-γ-glutamic acid (γ-PGA) goes beyond conventional skin hydration. It penetrates the skin barrier to deliver long-lasting hydration, strengthen the skin’s structure and keep the skin in good condition.
Unlike conventional humectants, AQUARICH®-OLIGO combines exceptional water-binding capacity with deep epidermal and dermal activity. It reduces transepidermal water loss, enhances elasticity and firmness and visibly improves wrinkles, pore visibility and overall skin texture.
Sustainably produced via bio-fermentation of Bacillus subtilis var. chungkookjang, AQUARICH®-OLIGO reflects our commitment to science and environmental responsibility. Its prebiotic effect supports beneficial skin microbiota and its ability to inhibit hyaluronidase helps maintain hyaluronic acid levels for plump, youthful skin.
Clinical studies have shown that AQUARICH®-OLIGO effectively hydrates the skin and strengthens the skin barrier. It reduces cellular senescence in the epidermal layers and enhances dermal resilience. For many skin parameters, it outperforms hyaluronic acid.
Complementary in-vitro studies confirm its barrier-strengthening properties by increasing components of the Natural Moisturizing Factor (NMF) and the cornified envelope. It promotes the synthesis of hyaluronic acid and collagen in the dermis while inhibiting hyaluronidase activity. Additionally, AQUARICH®-OLIGO provides protection against the harmful effects of UV radiation.
