The Black Tea Boosting Serum enhances skin elasticity with fermented black tea (kombucha), peptide, and adenosine, providing healthy energy and vitality to rejuvenate skin that has lost its strength. This serum is formulated with EWG graded green and safe ingredients, certified as zero-irritation, and contains Coptis Japonica to soothe the skin. Macadamia seed oil improves wrinkles and dry skin, while seaberry awakens the skin’s inner vitality and niacinamide brightens the complexion. It is recommended to use this serum in conjunction with Pyunkang Yul Enriched Cream and Deep Infusion Toner for a more moisturizing effect. The key ingredients include kombucha, fermented for 7 to 8 weeks, rich in polyphenol and catechin, to help keep skin firm and plump. The elastic, highly enriched formula replenishes the skin with nutrients, absorbing refreshingly without stickiness. To use, take an appropriate amount and gently massage onto areas of the skin that need care.
