    Product Description

    Ergothioneine (ethylthionine) is a naturally occurring amino acid derivative that is primarily synthesized by certain fungi and bacteria. It is a potent antioxidant that protects cells from oxidative stress. Due to its unique biological properties, ergothioneine has gradually gained attention in the cosmetics industry, especially in skin care products.
    Discover the power of Aogebio® Ergothioneine (EGT), the "longevity vitamin" scientifically proven to combat oxidative stress, reverse signs of aging, and enhance skin vitality. Recognized by leading skincare brands like La Mer and Estée Lauder, Ergothioneine is a rare, naturally occurring antioxidant that outperforms traditional actives like vitamin C and glutathione in protecting skin at the cellular level.
