Cos De BAHA Azelaic Acid (AZ) 10% Serum 30ml

Azelaic acid is one of skincare's quiet multitaskers, and the Cos De BAHA Azelaic Acid 10% Serum makes it accessible without a fuss. At a sensible 10% concentration, it targets the look of uneven tone, post-blemish marks, and the diffuse redness that often comes with congested, reactive skin — all in a no-frills serum that does its job and stays affordable.

Why people reach for azelaic acid

It is valued for supporting a clearer, more even-looking complexion, with a reputation for being gentler than many actives — which makes it a useful option for skin that finds strong acids or vitamin C too much. With steady use it helps soften the look of marks left behind by breakouts and brings a calmer, more uniform appearance to the surface.

Working it in

Apply a thin layer to clean skin once or twice a day, before moisturiser. As with any active, start slowly and see how your skin responds, and patch test first if you are sensitive. Daily sunscreen helps protect your progress on tone, especially under Bangladesh's strong sun. It layers well in a simple routine and pairs comfortably with niacinamide.
