Cos De BAHA Azelaic Acid 10% Serum – 30 ml Aloe-Based Lightweight Niacinamide & Panthenol for Blemish & Redness-Prone Skin

Cos De BAHA Premium Azelaic Acid 10% Serum is a lightweight, aloe-based facial serum formulated to help balance oily, blemish-prone and redness-prone skin while refining the look of pores and uneven tone.

This concentrated 30 ml serum combines 10% azelaic acid with supportive actives—niacinamide, panthenol and humectants—delivered in a fast-absorbing Korean-style formula. It’s built to layer under moisturizers and sunscreen in both morning and evening routines, offering targeted cosmetic benefits like a smoother-feeling texture and a more even appearance without a heavy finish.

How does this serum address blemish-prone and redness-prone skin?

The formula centers on azelaic acid at a 10% concentration, chosen for its compatibility with sensitive or reactive complexions when used appropriately. Niacinamide and panthenol help support skin comfort and the look of balanced oiliness, while aloe and humectants promote hydration so the formula feels gentle, not stripping.

• 10% azelaic acid in an aloe leaf extract base
• Niacinamide to help even skin tone visually
• Panthenol for hydration and skin feel
• Humectants like sodium hyaluronate, propanediol, propylene glycol

Can I layer it with other products in my routine?

Yes — the serum is designed to be lightweight and fast-absorbing, making it convenient to layer. Apply after cleansing and toning, then follow with a moisturizer and SPF in the morning. If using active treatments (retinoids, exfoliating acids), introduce the serum gradually and monitor tolerance.

• Apply to clean skin, pat in until absorbed
• Follow with moisturizer and sunscreen for daytime use
• Introduce gradually alongside other actives to assess compatibility
• Suitable for AM or PM layering

What texture and sensory experience should I expect?

The serum has a light, non-greasy texture based on aloe leaf extract and humectants for immediate slip and a hydrated finish. It absorbs quickly, leaving a smooth base that layers well under subsequent products without pilling or heavy residue.

• Aloe-based, fluid gel-like consistency
• Fast absorption with a non-oily finish
• Leaves skin feeling smooth and prepped for moisturizer
• Fragrance-minimal to reduce sensory irritation

Which botanical extracts are included and why are they here?

The formulation includes a selection of plant-derived extracts chosen for complementary cosmetic benefits and antioxidant support. These botanicals are incorporated to round out the sensory profile and provide additional soothing and natural-derived ingredients.

• Green tea (Camellia sinensis) extract for a calming antioxidant presence
• Bitter melon (Momordica charantia) and elderflower for plant-derived support
• Edelweiss extract for botanical complement to the formula
• Combined with humectants to maintain skin hydration

Who is this for: This serum suits people looking for a targeted, cosmetic-strength azelaic acid treatment in a lightweight, aloe-based vehicle — especially those with oily, blemish-prone or redness-prone complexions who prefer fast-absorbing, layerable products. It’s also a fit for anyone seeking a non-greasy daytime-friendly serum that pairs with moisturizers and sunscreens. If you use other potent actives, introduce the product gradually and patch-test to confirm personal tolerance.
