Cos De BAHA Azelaic Acid 10% Serum (AZ)

Cos De BAHA Azelaic Acid 10% Serum is a lightweight, fast-absorbing aloe-based serum with a clear, slightly viscous texture and no discernible scent — a budget-friendly Korean skincare pick formulated for blemish-prone, redness-prone, and oily skin types.

Suitable for both AM & PM routines, this serum slots in after cleansing and toning, and layers seamlessly under moisturizer and sunscreen without pilling or heaviness.

The formula leads with Azelaic Acid at 10% — a multitasking acid that gently exfoliates, targets acne-causing bacteria, and helps fade post-blemish marks. Niacinamide (Vitamin B3) works alongside it to regulate oil production, strengthen the skin barrier, and even out skin tone. Panthenol (Vitamin B5) calms inflammation and replenishes the skin, while Sodium Hyaluronate delivers lightweight hydration deep into the skin’s surface. An aloe base rounds out the formula with added soothing support, and botanical extracts — including Green Tea, Elderflower, and Edelweiss — contribute antioxidant and skin-supporting benefits.

• Targets active breakouts and helps prevent future blemishes by reducing acne-causing bacteria and clearing clogged pores.
• Fades post-acne hyperpigmentation, dark spots, and uneven skin tone with consistent use over time.
• Calms visible redness and irritation, making it a strong option for those with rosacea or reactive skin.
• Hydrates and strengthens the skin barrier without adding greasiness, leaving skin feeling plump and balanced.

How to Use: After cleansing and toning, apply 1–2 drops of serum onto the face and gently massage until absorbed. Use morning, evening, or both, followed by moisturizer. If you have sensitive skin, start by mixing with another serum to build tolerance. Always apply SPF in the morning. Discontinue use if significant irritation occurs.
