The Klued 5% Niacinamide Serum has become one of my favorite serums! It’s super lightweight, absorbs quickly, and gives my skin that healthy, natural glow. I love how it helps even out my skin tone and keeps my skin smooth and hydrated throughout the day. What makes it even better is how perfectly it pairs with the Klued 5% Mandelic Acid Clarifying Toner — they work so well together! The toner gently exfoliates, while this serum brightens and calms the skin right after. Using them as a duo gives me that fresh, glass-skin finish.
