Azelaic acid and niacinamide both help with oily, acne-prone, and pigmented skin but work differently and have unique benefits.

🩺 Mechanism of Action

• Azelaic acid works by killing acne-causing bacteria, reducing inflammation, and gently removing dead skin cells (keratolytic effect). It also inhibits melanin production, helping with pigmentation.
• Niacinamide (vitamin B3) reduces inflammation, regulates oil production, strengthens the skin barrier, and inhibits pigment transfer to lighten dark spots.

🩺 Effects on Oily and Acne-Prone Skin

• Azelaic acid directly targets acne bacteria and reduces blocked pores, making it effective for active acne and oily skin.
• Niacinamide helps by calming inflammation and controlling excess oil, improving acne-prone skin's overall appearance and texture.

🩺 Effects on Pigmentation

• Azelaic acid is effective for fading pigmentation by blocking melanin synthesis, often used for melasma and post-inflammatory hyperpigmentation.
• Niacinamide reduces pigmentation by preventing pigment transfer to skin cells, resulting in a gradual, even skin tone improvement.

🩺 Additional Benefits and Considerations

• Azelaic acid may cause mild irritation initially but suits sensitive and acne-prone skin well under guidance.
• Niacinamide is generally well-tolerated, also improves skin barrier function, and can reduce redness and sensitivity.
• Both can be combined or used according to tolerance, but consulting a dermatologist is recommended for personalized advice and optimal results.

Seeing a dermatologist can help decide which ingredient or combination suits your skin type best.
