Cos De BAHA Azelaic Acid 10 Serum (AZ) (30ml) is a potent corrective serum featuring 10% Azelaic Acid combined with Niacinamide, Panthenol, and Hyaluronic Acid. This multi-tasking serum targets acne, rosacea-induced redness, and hyperpigmentation while simultaneously soothing inflammation. Formulated with an Aloe Vera base instead of water, it provides a calming yet effective solution for resurfacing the skin and clearing out clogged pores for a more uniform complexion.
The Multi-Tasking "Hero" Ingredient
Azelaic Acid is a naturally occurring acid that is gentler than many AHAs or BHAs but incredibly effective. It acts as a gentle exfoliant that stays deep within the pores to kill acne-causing bacteria and reduce inflammation. For those who struggle with "red spots" left behind after a breakout (PIE), this 10% concentration is the ideal strength to fade discoloration without causing the irritation often associated with stronger actives.
Key Features & Benefits:
Redness & Rosacea Relief: Specifically targets the underlying inflammation that causes facial flushing and sensitivity.
Acne & Clog Fighter: Helps to normalize the shedding of skin cells within the pores, preventing the formation of blackheads and whiteheads.
Brightening Synergy: Works alongside Niacinamide to inhibit melanin production, helping to fade dark spots and even out skin tone.
Aloe Vera Base: Unlike many serums that use purified water, this uses Aloe barbadensis leaf extract to provide immediate hydration and cooling upon application.
Texture Smoothing: Gradually refines the skin's surface, making it an excellent prep step for achieving a "poreless" finish with your Maybelline Fit Me Foundation.
Skin Type: Ideal for Acne-prone, Rosacea-prone, Oily, and Sensitive skin.
Safety: Paraben-free, Colorant-free, Alcohol-free, and Fragrance-free.
How to Use for a Clear, Calmed Complexion:
Prep: Cleanse your face and apply a hydrating toner. Ensure your skin is completely dry before applying Azelaic Acid to minimize any potential tingling sensation.
Apply: Dispense 1–2 drops and spread evenly across the face, focusing on areas with redness or breakouts.
Layer: Once absorbed, follow with a soothing moisturizer like the iUNIK Centella Calming Gel Cream to seal in the actives.
Routine Tip: It can be used both morning and night. However, if you are also using the Anua Niacinamide 10% + TXA 4% Serum, consider using one in the morning and the other at night to avoid overwhelming the skin.
Sun Protection: Azelaic Acid doesn't make skin as sensitive to the sun as Retinol, but you should still always finish your morning routine with the SKIN1004 Hyalu-Cica Sun Serum to protect your progress.
⚠️ A Peer Note on Sensation: It is very common to feel a slight "itchy" or tingling sensation for the first few minutes after application during the first week of use. This is normal for Azelaic Acid! If it persists, you can "buffer" the serum by mixing a drop into your moisturizer.
