Dr.Althea 15% Niacinamide Purity Serum, 30ml Face Serum

Niacinamide has become one of the most searched-for ingredients in skincare, and serums built around a high concentration of it, like this 15% formula, are generally positioned toward customers who have already identified oil control and pore appearance as their main concerns rather than customers still exploring general hydration. The "purity" naming reflects a common trend in niacinamide serums of pairing the core ingredient with a shorter, more streamlined ingredient list.

Pairing niacinamide with zinc PCA is a well-established combination in oil-control serums, since zinc is often included alongside niacinamide specifically to help balance formulas that might otherwise feel drying at higher niacinamide concentrations. The inclusion of rice ferment filtrate and grape seed extract reflects a broader Korean skincare trend of layering in fermented and antioxidant-rich ingredients even within an actives-focused serum.

Within a routine, a niacinamide serum like this typically follows toner and precedes moisturizer, and is often chosen by customers who want to address oiliness or texture without moving to a stronger active like retinol or a higher-percentage acid. Because niacinamide is broadly compatible with most other skincare ingredients, it's also commonly layered alongside vitamin C or hydrating serums as part of a fuller routine, a flexibility that helps explain its popularity across skin types.
