🔬 How It Actually Works
The true acid form of Vitamin B3 (distinct from Niacinamide). It acts as an aggressive vasodilator, causing a temporary but massive rush of blood, oxygen, and nutrients to the skin.
💖 Why your skin loves it
Provides an intense "flush" that oxygenates tissue and heavily stimulates collagen.
💡 Pro Tip
It will cause your face to turn bright red and warm for 20 minutes (the "niacin flush"). Do not use if you have Rosacea.
⚖️ Myth vs. Fact
The Myth
