How Niacinamide Treats Acne & Fades PIH
Niacinamide (Vitamin B3) is a multi-tasking active ingredient that works through two distinct biological pathways:
- Sebum Regulation: Reduces facial sebum excretion rate (SER) by up to 30%, shrinking enlarged pore appearance and preventing comedone formation.
- Melanosome Transfer Inhibition: Blocks the physical transfer of pigment-filled melanosomes from deep melanocytes into superficial skin cells by up to 68%.

Expert FAQ: Niacinamide
Is 5% or 10% Niacinamide better for acne and dark spots?
5% Niacinamide is the dermatologist-recommended sweet spot. Clinical studies show 5% achieves maximum melanosome transfer blocking (up to 68%) and sebum reduction with near-zero risk of irritation. 10% Niacinamide can cause redness or micro-flares in sensitive Indian skin.
How does Niacinamide fade dark spots?
Unlike tyrosinase inhibitors that stop melanin creation, Niacinamide blocks the transfer of melanosomes (pigment packages) from melanocytes into surrounding keratinocyte skin cells.
Can I use Niacinamide every day in my morning routine?
Yes! Niacinamide is non-photosensitizing and strengthens the skin barrier. It is ideal for daily AM and PM application under sunscreen.
