Cos De BAHA Azelaic Acid 15% + MSM 1% (AZ15) Serum 30ml

Cos De BAHA Azelaic Acid 15% + MSM 1% (AZ15) Serum is a lightweight, fast-absorbing, non-comedogenic treatment serum from South Korea, clinically positioned as a high-strength solution for acne-prone, hyperpigmentation-prone, and sensitive skin types.

Suitable for both AM & PM use. Apply after cleansing and toning, before moisturizer. Follow with SPF during the day. Start with once daily and increase frequency as tolerated.

The hero active is Azelaic Acid at 15% — a potent concentration that targets acne-causing bacteria, reduces inflammation, and fades post-blemish dark spots. MSM (Methylsulfonylmethane) at 1% enhances ingredient absorption while calming irritation and supporting skin elasticity. Centella Asiatica Extract and Madecassoside reinforce the barrier and soothe redness. Ceramide NP locks in moisture and restores barrier integrity, while Sodium Hyaluronate and Hydrolyzed Hyaluronic Acid deliver layered, deep hydration. Panthenol and Allantoin round out the formula with added calming and skin-softening support.

• Targets active breakouts and prevents new blemishes by reducing acne-causing bacteria and excess sebum activity.
• Visibly fades post-acne marks, hyperpigmentation, and uneven skin tone with consistent use over time.
• Calms redness, inflammation, and sensitivity without the photosensitivity risk associated with AHA exfoliants.
• Hydrates and fortifies the skin barrier so active-strength treatment doesn’t come at the cost of comfort or resilience.

How to Use: Dispense 2–3 drops onto fingertips and smooth evenly over cleansed, dry skin, avoiding the eye and lip area. Gently pat until fully absorbed, then follow with a moisturizer. In the morning, always finish with a broad-spectrum sunscreen. Free from synthetic fragrances, parabens, artificial colorants, and harsh alcohols.
