Cos De BAHA Vitamin C 15% Serum costs ৳1,290 in Bangladesh. It is in stock and ships cash on delivery nationwide from Shampoo BD. It was previously ৳1,550.
How do I know this serum is genuinely imported and not refilled locally?
A genuine Cos De BAHA bottle arrives with an unbroken factory seal at the neck, which cannot be resealed perfectly by hand once opened. The dropper tube inside sits flush against the bottle shoulder with no air gap, and the liquid appears uniformly clear with no separation or cloudiness. If the seal shows creasing, the cap feels loose, or the bottle looks tampered with, the serum has likely been opened and repackaged before reaching you.
What is the right way to apply this vitamin C serum to my face?
Place two to three drops on clean, completely dry skin each morning, then gently pat across your cheeks, forehead, and chin with your fingertips. Wait sixty seconds for the serum to absorb fully before layering your moisturiser or sunscreen on top. Using more than the recommended amount wastes product and does not improve results, so measure carefully with the dropper each time.
What should I expect when I use this product for the first time?
Most first-time users notice a slight tingling sensation on the skin during the first week, which is normal and fades as your skin adjusts. A single 30ml bottle lasts approximately two to three months when used daily by one person. Keep the bottle in a cool, dark cupboard at home and never leave it on a sunny windowsill, as vitamin C serums lose strength when exposed to heat and light.
