Cos De BAHA Azelaic Acid 10% Serum is a skincare product that contains 10% Azelaic Acid as the active ingredient. Azelaic Acid is a naturally occurring substance found in grains such as barley, wheat, and rye. It is used in skincare to address various skin concerns such as acne, rosacea, hyperpigmentation, and uneven skin tone. The serum may improve skin texture and brighten the complexion.

• Acne treatment: Azelaic Acid has been shown to be effective in reducing the appearance of acne by unclogging pores and reducing inflammation.
• Brightening: Azelaic Acid has a brightening effect on the skin, reducing the appearance of hyperpigmentation, dark spots, and uneven skin tone.
• Anti-inflammatory: Azelaic Acid has anti-inflammatory properties, making it suitable for those with rosacea and sensitive skin.
• Antimicrobial: Azelaic Acid has antimicrobial properties, making it effective in killing the bacteria that cause acne.
• Improving skin texture: Azelaic Acid can improve skin texture by increasing skin cell turnover and smoothing rough skin.

Key ingredient:

• Carrier agents: These help to deliver the active ingredient to the skin and improve its absorption.
• Humectants: These help to hydrate the skin and keep it moisturized.
• Preservatives: These help to prevent the growth of bacteria and extend the shelf life of the product.
• Stabilizers: These help to maintain the stability and integrity of the product.
