Cos De BAHA A5 Azelaic Acid 5% Serum 30 ml

The Cos De BAHA A5 Azelaic Acid 5% Serum is a gentle, beginner-friendly azelaic acid serum for skin working on the look of redness, uneven tone, and post-blemish marks — common concerns for sensitive and acne-prone skin in Bangladesh. At an approachable 5% concentration, this Azelaic Acid 5% Serum offers the multitasking benefits of azelaic acid in a milder form than higher-strength options, making it easier to tolerate for reactive skin.

Why azelaic acid at 5%

Azelaic acid is one of skincare's quiet multitaskers, valued for supporting a clearer, more even-looking complexion and for its reputation as a gentler active that helps with the appearance of redness, marks, and bumpy texture. The 5% concentration in the Cos De BAHA A5 Azelaic Acid 5% Serum is deliberately approachable — strong enough to work on tone and clarity, gentle enough for sensitive, reactive, or redness-prone skin that finds higher-percentage actives too much.

Who it suits

This azelaic acid serum is a good fit for sensitive, acne-prone, and redness-prone skin working on the look of uneven tone, post-blemish marks, and diffuse redness. Because azelaic acid is well tolerated, it is a friendly choice for those new to actives, and it pairs comfortably with niacinamide. Patch test first if your skin is highly reactive.

How to use it

Apply a thin layer of the Cos De BAHA A5 Azelaic Acid 5% Serum to clean skin, once or twice a day, before your moisturiser. Start slowly and see how your skin responds, building up as tolerated. Daily sunscreen helps protect your progress on tone and marks, which is especially important under Bangladesh's strong UV.

What to expect

Working on tone, redness, and post-blemish marks is a gradual process that rewards weeks of consistency. Used steadily alongside sun protection, the Cos De BAHA A5 Azelaic Acid 5% Serum is a gentle, affordable way to work toward clearer, calmer, more even-looking skin without the irritation of stronger actives.
