Description

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.

    While the COS DE BAHA Niacinamide Serum is effective, it did not fully meet my expectations.

  15. Tasnuba M. –

    I recently tried the COS DE BAHA Niacinamide 20% + Zinc 4% Serum and I must say, it exceeded my expectations. As a fan of K-Beauty products, this serum has become a staple in my skincare routine. Not only does it effectively target my skin concerns, but it also leaves my face feeling smooth and refreshed. If you’re looking for a high-quality face serum, look no further than this amazing product from COS DE BAHA.

    I recently discovered this amazing K-Beauty face serum and it has completely transformed my skin! The serum is lightweight and absorbs quickly, leaving my skin feeling smooth and hydrated. The combination of niacinamide and zinc has helped to reduce redness and control oil production. I have noticed a significant improvement in my skin’s texture and overall appearance since incorporating this serum into my skincare routine. I highly recommend this serum to anyone looking to achieve a healthy, glowing complexion!

    I recently tried the COS DE BAHA Niacinamide 20% + Zinc 4% Serum and I am blown away by the results! As a fan of K-Beauty products, this serum is now a staple in my skincare routine. Not only does it feel lightweight on my skin, but it has also helped to reduce my acne and brighten my complexion. After using it for a few weeks, I can confidently say that this serum is a game-changer for anyone looking to improve their skin. I highly recommend giving it a try!

    এই COS DE BAHA Niacinamide 20% + Zinc 4% Serum টি আমার চেহারায় আমার জন্য একটি অসাধারণ K-Beauty ফেস সিরাম হিসেবে কাজ করে। এটি আমার ত্বকের অবস্থা সুধারে সাহায্য করে এবং ত্বকের তাল নির্মাণ কমাতে সাহায্য করে। এই সিরামটি আমার চেহারাকে উজ্জ্বল এবং স্বস্তি করে এবং আমি এর ব্যবহারে অত্যন্ত সন্তুষ্ট।
