PURITO’s New Actives: Azelaic & Kojic Acid vs TXA & Retinal
Posted by Skinsider Team on 5th Feb 2026
Why actives matter in modern K-Beauty skincare
In Korean skincare, active ingredients are used strategically - not aggressively. Instead of over-exfoliating or overwhelming the skin, K-beauty focuses on combining proven actives with barrier-supporting ingredients to deliver results while maintaining skin comfort.
With the launch of these two new PURITO serums, the brand offers targeted solutions for uneven tone, blemishes, pigmentation and early signs of ageing - using carefully balanced concentrations of azelaic acid, kojic acid, tranexamic acid (TXA) and retinal.
Let’s break down what each serum does, who it’s best for, and how to use it correctly.
