K-Secret Glow Serum: Niacinamide 15% + Yuja 30ml

K-Secret’s Glow Serum: Niacinamide 15% + Yuja is a brightening face serum designed to help reduce the look of dark spots and create a more radiant, even-toned complexion. With 15% niacinamide at its heart, it targets unevenness for a “clarity + radiance” look, while the yuja (Korean citrus) adds a fresh, vitamin-rich feel.

What makes it stand out is the combination of high-strength niacinamide with a thoughtfully built formula that supports everyday glow. The serum is described as having a lightweight, fast-absorbing, non-greasy texture, plus a moisture-conscious approach to help prevent moisture loss. It’s also positioned as a post-breakout mark and hyperpigmentation-friendly step when used consistently.

Key ingredients and technology notes include yuja (Citrus Junos Fruit Oil), panthenol and glutathione for hydration support, squalane for comfort, and Agar Gum Capsules to help lock in moisture. You can apply it after cleansing and toning, then gently pat in for better absorption.
