NiacinamideFor Skin Barrier Support
A versatile ingredient that strengthens the skin barrier, reduces inflammation, and improves redness in rosacea-prone skin. Particularly effective at lower concentrations (2-5%) for sensitive skin.
Key Benefits
Barrier Strengthening
Increases ceramide production and improves skin's natural moisture retention.
Reduces Redness
Anti-inflammatory properties help calm rosacea-related redness and flushing.
Improves Hydration
Enhances skin's ability to retain moisture, reducing dryness and tightness.
Well-Tolerated
Generally suitable for sensitive skin, especially at lower concentrations.
How It Works
Niacinamide (Vitamin B3) works through multiple pathways to improve skin health. It's particularly beneficial for rosacea-prone skin due to its ability to strengthen the compromised skin barrier and reduce inflammation.
Primary Actions:
- Barrier Repair: Increases ceramide, free fatty acid, and cholesterol production
- Anti-inflammatory: Inhibits inflammatory cytokines and reduces redness
- Antioxidant: Protects against environmental damage and oxidative stress
- Sebum Regulation: Helps normalize oil production without over-drying
Usage Guidelines
Recommended Approach
- Start with low concentration (2-5%)
- Can be used once or twice daily
- Works well in serums, moisturizers, or toners
- Compatible with most other skincare ingredients
Concentration Considerations
- 2-5%: Ideal for rosacea-prone skin, well-tolerated
- 10%: May be tolerated by some, but higher risk of irritation
- Lower concentrations often provide benefits without irritation
Frequently Asked Questions
What concentration of niacinamide is best for rosacea?
Lower concentrations (2-5%) are generally best for rosacea-prone skin. These provide barrier benefits without the irritation risk that higher concentrations (10%+) may pose.
Can I use niacinamide with azelaic acid?
Yes, many people use them together successfully. Niacinamide can help strengthen the skin barrier, potentially reducing irritation from azelaic acid.
How long until I see results with niacinamide?
Barrier improvements may be noticeable within 2-4 weeks, while anti-inflammatory effects and redness reduction typically take 4-8 weeks of consistent use.
Can niacinamide cause flushing?
While rare, some people may experience flushing from high concentrations (10%+). This is less common with lower concentrations suitable for rosacea.
