Cos De BAHA 10% Niacinamide Booster Serum with 1% Zinc 30ml (N) is a lightweight Korean skincare serum designed to control oil, minimize pores, and fade dark spots in hot, humid climates like Bangladesh. This N Serum delivers 10% Niacinamide and 1% Zinc PCA to regulate sebum, strengthen the skin barrier, and calm post-acne marks caused by sweat and pollution. It is perfect for oily, combination, and acne-prone skin that faces daily dust and urban grime in Dhaka. The formula includes soothing Aloe, hydrating Sodium Hyaluronate, and antioxidant botanical extracts to protect and repair sensitive skin. Made in South Korea and 100% authentic, it helps Bangladeshi users achieve clearer, brighter, and more even-toned skin without greasiness.
After cleansing your face, pat skin dry and apply 1 to 2 drops of the serum onto your face and neck.
Gently pat until fully absorbed, then follow with your regular moisturizer and sunscreen in the morning or night cream in the evening.
Use twice daily, morning and evening, and always patch test first if you have very sensitive skin.
