About Cos De Baha Niacinamide 20% + Zinc 4% Serum

Cos De Baha Niacinamide 20% + Zinc 4% Serum 30ml is a no-frills, high-performance active serum built for visible results. While most niacinamide serums on the market sit between 5% and 10%, this formula pushes the concentration to 20% — delivering a significantly stronger dose of one of skincare's most clinically validated multitasking ingredients. Paired with 4% zinc PCA, it creates a targeted treatment for oily, congested, and pigmented skin that responds to high-strength actives.

Niacinamide at 20% works faster and more aggressively on dark spots, enlarged pores, and uneven skin tone than standard concentrations. It regulates sebum production at a sebaceous gland level, making it particularly effective for oily and combination skin types that struggle with shine, congestion, and post-acne marks in Bangladesh's humid and polluted environment. Zinc PCA reinforces this sebum control, adds antibacterial protection against acne-causing bacteria, and reduces surface inflammation that leads to persistent breakouts.

The formula is stripped back and straightforward — no fragrance, no unnecessary additives, just a water-based, lightweight serum that absorbs quickly, layers under any moisturizer, and gets to work without irritation. For anyone in Bangladesh looking for a high-strength active serum at an accessible price point, this is one of the most direct and effective options available.
