Azelaic Acid vs. Niacinamide: What's the Difference?
Edited by Aimie Carlson || By Janet White || Published on January 3, 2024
Azelaic acid is an organic compound used in skincare for its antibacterial and anti-inflammatory properties, while niacinamide is a form of vitamin B3 used for skin hydration and reducing redness.
Key Differences
Azelaic acid, a naturally occurring acid found in grains, is known for its antibacterial properties, making it effective in treating acne. Niacinamide, also known as nicotinamide, is a water-soluble vitamin that works to strengthen the skin barrier and improve skin texture.
In skincare, azelaic acid is used to reduce inflammation and hyperpigmentation, often recommended for rosacea and acne scars. Niacinamide is celebrated for its ability to retain moisture, reduce redness, and minimize the appearance of pores.
Azelaic acid functions by inhibiting the production of keratin, a protein which can block pores and lead to acne, and by reducing melanin production. Niacinamide works by increasing ceramide synthesis in the skin, enhancing its protective barrier and preventing water loss.
The effectiveness of azelaic acid is pronounced in treating mild to moderate acne and evening out skin tone. Niacinamide, being gentler, is suitable for sensitive skin, offering anti-aging benefits by reducing wrinkles and fine lines.
Azelaic acid can be used in higher concentrations for more intense treatments but may cause skin sensitivity. Niacinamide is typically well-tolerated in various concentrations, making it a versatile ingredient in many skincare products.
