Niacinamide vs Azelaic Acid – Redness & Tone
Overview
Niacinamide and Azelaic Acid are two dermatologist-approved ingredients that work to calm redness, refine pores, and brighten tone. 🌿 While Niacinamide (Vitamin B3) strengthens your skin’s barrier, balances oil, and soothes sensitivity, Azelaic Acid gently exfoliates, targets acne bacteria, and fades post-acne marks — together, they form a powerful duo for even, radiant skin.
When to Choose
- 💧 Redness, oil, or enlarged pores? → Use Niacinamide (2–5%) daily.
- 🌙 Post-blemish marks or uneven tone? → Use Azelaic Acid (10–15%) at night.
- ✨ Combination skin? → Niacinamide in the morning, Azelaic Acid at night.
Layering & Compatibility
These two are synergistic — they enhance each other’s soothing and brightening effects. Begin with one for two weeks, then layer both once your skin adjusts. Always patch test before full application to prevent irritation.
🔬 Mechanism of Action
- Niacinamide: Strengthens the lipid barrier, reduces water loss, controls sebum, and decreases melanin transfer — leaving skin calm and even-toned.
- Azelaic Acid: Gently exfoliates, kills acne-causing bacteria, reduces keratin buildup, and inhibits tyrosinase, a key enzyme in pigmentation formation.
