Visible dark spots and stubborn pigmentation are targeted by the K-SECRET SEOUL 1988 Glow Serum: Niacinamide 15% + Yuja. This high-strength formula uses a potent 15% concentration of Niacinamide to balance oil production and even out skin tone, while Yuja fruit oil and Vitamin C provide a natural brightening boost. By blending Glutathione and Tranexamic Acid, the serum works to fade the look of old blemishes and redness for a clearer, more uniform complexion. The lightweight texture sinks in quickly to provide moisture through Squalane and Shea Butter without any greasy residue. It offers a practical way to brighten a dull face and smooth out rough texture using a mix of traditional extracts and modern brightening agents. Why You Will Love It: High-Strength Niacinamide: Contains 15% Vitamin B3 to help refine pores and significantly improve the appearance of uneven skin tone. Potent Brightening Complex: Blends Glutathione and Tranexamic Acid to target pigmentation and fade the look of dark spots.
