A vegan fermented extract from Jeju seabreezed Yuza (Citrus junos), developed through Lactobacillus rhamnosus fermentation to enhance postbiotic activity. This ingredient offers multiple skin benefits such as barrier reinforcement, soothing, brightening, and anti-pollution protection.

L-PDRN FIRST™ is a vegan, world’s first Biome-PDRN. Extracted from Lactobacillus rhamnosus derived from Glycine soya, L-PDRN FIRST™ is a sustainable, microbial-derived alternative to salmon-based PDRN (Polydeoxyribonucleotide), produced through controlled microbial fermentation and purification.
L-PDRN FIRST™ uniquely activates two regeneration pathways: the classical FAK–AKT cascade and the additional p38/ERK pathway. It is 2–8× lighter at the molecular level, enabling deeper and faster skin penetration to support superior skin repair and next-level antioxidant defense.
