One Thing Niacinamide 10% 150ml

A high-concentration brightening toner powered by 10% Niacinamide — one of the most clinically proven ingredients in K-Beauty for pigmentation control, pore refinement, and skin tone evening. This lightweight, fast-absorbing formula works by blocking melanin transfer at the cellular level, making it an essential step in any brightening or melanin management ritual.

What It Does

• Melanin Transfer Blockade: 10% Niacinamide interrupts the transfer of melanin to skin cells, visibly reducing dark spots, hyperpigmentation, and uneven tone
• Pore Refinement: Regulates sebum production and minimizes the appearance of enlarged pores for a smoother, more refined complexion
• Barrier Strengthening: Reinforces the skin's natural moisture barrier to reduce sensitivity and improve overall skin resilience
• Hydration Boost: Lightweight toner texture delivers instant hydration while prepping skin for subsequent serums and moisturizers
• Spot Treatment Support: Apply with a cotton swab directly to dark spots for targeted brightening treatment

How To Use

After cleansing, apply to a cotton pad and sweep across the face, or pat directly onto skin with fingertips. For targeted spot treatment, apply with a cotton swab directly to areas of concern. Use morning and/or evening. Follow with serum and moisturizer. Consistent use over 4–8 weeks delivers optimal brightening results.
