FAQS
Can I use Vitamin C and Niacinamide together?

Earlier myths claimed they neutralize each other, but recent dermatological research confirms they’re safe and even more effective when combined. Vitamin C brightens and protects against free radicals, while Niacinamide calms, hydrates, and strengthens your skin barrier — giving you balanced, radiant skin.
Which is better for pigmentation — Vitamin C or Niacinamide?
Both help with pigmentation, but in different ways. Vitamin C targets existing dark spots by reducing melanin production, while Niacinamide helps prevent new spots by reducing inflammation and controlling excess oil. For stubborn pigmentation, layering both can deliver faster and more even results.
