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

Hyperpigmentation and uneven skin tone are common concerns in Bangladesh, where intense UV exposure and pollution can trigger persistent dark spots and redness. The Cos De Baha Azelaic Acid 10% Serum (AZ) is a targeted treatment designed to address these issues by calming inflammation and brightening the complexion. Unlike many aggressive brightening agents, this serum focuses on gentle correction, making it a reliable option for those who need to manage redness or post-acne marks without compromising their skin barrier.

What is Cos De Baha Azelaic Acid 10% Serum?

Cos De Baha Azelaic Acid 10% Serum is a concentrated treatment that uses a 10% concentration of azelaic acid to help even out skin tone and soothe redness. It works by regulating melanin production and providing antibacterial support, making it an effective choice for managing the appearance of hyperpigmentation and congestion.

The active ingredient, Azelaic Acid, is a dicarboxylic acid that helps exfoliate the skin surface at a cellular level. It is particularly effective at targeting the enzymes responsible for dark spots, helping to fade the look of acne scars and sun damage over time. To balance this potency, the formula includes Glycerin, a humectant that draws moisture into the skin to prevent the dryness often associated with acid treatments. The addition of a skin-soothing copolymer ensures the texture remains smooth and comfortable, even on reactive skin types.

Who it suits

• Skin prone to post-inflammatory hyperpigmentation (the dark marks left behind after a breakout)
• Those dealing with persistent redness or facial flushing
• Oily or combination skin looking to manage congestion and uneven texture
• Anyone seeking a gentler alternative to high-strength retinoids or vitamin C for brightening

While formulated to be gentle, those with extremely sensitive skin should patch test first. If you are using other strong actives like Tretinoin or high-percentage AHAs, introduce this serum slowly to avoid irritation.

How to apply

1. Start with a clean, dry face after your morning or evening cleanse
2. Apply 2–3 drops of the Cos De Baha Azelaic Acid 10% Serum to your face and neck
3. Gently pat the product into the skin rather than rubbing to ensure even distribution
4. Wait 1–2 minutes for the serum to absorb fully before moving to the next step
5. If using in the morning, you must follow with a broad-spectrum sunscreen; azelaic acid helps even skin tone, but UV exposure will undo your progress

What to expect

When you buy azelaic acid serum Bangladesh price comparisons often focus on concentration, but consistency is what actually delivers results. You may feel a slight, temporary tingling sensation upon application—this is common with acid-based serums. Do not expect an overnight transformation; skin-brightening-actives require patience. You will likely notice a more calm, even-toned complexion after 4 to 12 weeks of regular use. Because the humidity in Dhaka can make skin feel heavy, this lightweight-feeling serum is a practical addition to a routine that needs to feel breathable.
