Niacinamide (Vitamin B3) Cream

In brief

Niacinamide (vitamin B3) is one of the most versatile and well-tolerated skincare ingredients.

👉 Benefits are gradual but consistent.

🟢 What it does (main evidence)

• Strengthens the skin barrier.
• Helps regulate sebum production.
• Reduces redness and inflammation.

🟡 What is unclear

🔴 What it does NOT do

• Does not remove deep wrinkles.

Concentrations & forms
