Beauty of Joseon Green Tea Hyaluronic Acid Moisture Calming Serum

What is this product?

Beauty of Joseon's Green Tea Hyaluronic Acid Moisture Calming Serum (30ml) genuinely centers on what its name says: green tea water at 8.55 percent functions as a second base alongside plain water, and sodium hyaluronate is dosed at 1,500ppm. Niacinamide, coptis root and centella extracts back the calming half, though no brand-run test for this exact serum was found. No fragrance, no pH and no container form are disclosed for this SKU, and the ingredient statement itself was recovered from a retail listing rather than the brand's own detail page.

What makes it different?

Green tea water at 8.55 percent, disclosed and high enough to act as a functional second base rather than a trace botanical, is the structural fact that separates this from a serum where green tea is a name-only ingredient. A dosed 1,500ppm sodium hyaluronate backs the hydration half concretely. What is missing is any brand-run test connecting the calming claim to a measured result, and no brand-hosted product page for this exact SKU turned up across the six archived pages, so every fact here traces back to a matched retail listing rather than the brand's own words.
