Vitamin C charges up the skin; it gives an immediate glow. Niacinamide also helps in brightness but doesn't seem to have a direct effect like Vit C; Niacinamide works slowly to show the impact.
Niacinamide balances sebum production and makes it less clogging the pores. Vitamin C doesn't change sebum composition but prevents oxidation of sebum. Oxidation of sebum can clog pores. Also, Niacinamide is an antioxidant and can prevent sebum oxidation.

Both Vitamin C and Niacinamide will work towards reducing dark spots, but fading away existing ones takes 6months to 12 months for Indian Skin Types with regular use of vitamins, exfoliating acids and sunscreen.
Niacinamide can prevent water loss from the skin. Vitamin C doesn't do much to decrease dryness. Dryness is challenging to handle, most rich creams block pores and cause acne. Niacinamide works beautifully by balancing sebum by making it less pore-clogging and also dryness reduced.
As you can see, Vitamin C plays a significant role in Radiance, Dark spots and wrinkles whereas Niacinamide helps in Acne, Dryness and Dark spots. So choose the product according to skin issues.
