Both azelaic acid and niacinamide are effective ingredients for treating hyperpigmentation, but they work in different ways.
Azelaic Acid
- How it works: Azelaic acid is a dicarboxylic acid that inhibits tyrosinase, an enzyme responsible for melanin production. It also has anti-inflammatory properties, which can help reduce redness and irritation associated with hyperpigmentation.
- Benefits:
- Reduces the appearance of dark spots and uneven skin tone.
- Can be used on sensitive skin.
- May improve acne and reduce breakouts.
Niacinamide
- How it works: Niacinamide, a form of vitamin B3, helps regulate melanin production and reduce inflammation. It also strengthens the skin barrier, making it more resistant to damage and hyperpigmentation.
- Benefits:
- Improves skin tone and texture.
- Reduces redness and inflammation.
- May help with acne and other skin concerns.
Which One is Better?
The best ingredient for you depends on your specific skin concerns and preferences.
- Azelaic acid is generally more effective for treating severe hyperpigmentation and inflammatory acne.
- Niacinamide is a good choice for mild hyperpigmentation and sensitive skin.
It's important to note that both ingredients can be used together for a synergistic effect. However, it's best to consult with a dermatologist to determine the best treatment plan for your individual needs.
