Niacinamide 20% + Zinc 4% Serum - 30ml
COS DE BAHA Niacinamide 20% + Zinc 4% Serum 30ml is a K-beauty face serum with both active percentages clearly stated in the title. It is built for buyers comparing targeted serums and wanting a stronger niacinamide-and-zinc option in a 30ml bottle.
Why It Stands Out
The standout detail is the clear formula positioning: 20% niacinamide plus 4% zinc. That makes the product easy to distinguish from lower-strength niacinamide serums, basic hydrating serums, or toners with no percentage stated.
Best For
Best for skincare users seeking a focused serum step for excess oil look, visible unevenness, and texture care within a layered routine.
How to Use
Apply a small amount after cleansing and toning, then follow with moisturizer. Introduce gradually if the routine already contains other strong actives.
Benefits
- Features confirmed 20% niacinamide and 4% zinc in the title.
- Helps support a more balanced-looking skincare routine.
- 30ml size is convenient for daily serum use.
- Layers before cream or sunscreen without replacing moisturizer.
Good to Know
The batch confirms the active percentages in the product name, but does not list the complete ingredient deck, pH, fragrance status, or skin-type claim.
