This anti-aging essence delivered with the antioxidant power of Single Extract Formula™ and created using the patented Full Body Extraction™ promotes prebiotics to pre-tox, preventing further signs of skin aging. Vintage Tea Leaf™, containing green tea's precious substance Catechin, provides improvement in the appearance of skin clarity, texture and elasticity. It carefully utilizes green tea cultivated from the Dolsongi Green Tea Garden; the first of the three green tea gardens that AMOREPACIFIC owns and operates on Jeju Island off the South Coast of Korea. The green tea leaves are handpicked and naturally fermented in optimal conditions for 50 days. These fermented leaves are then transferred by tea masters and placed into "onggi's", traditional Korean earthware band buried in the earth, to age naturally for another 50 days. After 100 days of waiting and a 24-hours slow extraction process, AMOREPACIFIC's Vintage Single Extract Essence is perfected.
