Niacinamide vs Vitamin C: Which The Ordinary Serum Is Right for You?

Niacinamide and Vitamin C are two of the most talked-about ingredients in The Ordinary's lineup, and both promise brighter, more even-looking skin. But they work in different ways, suit different concerns, and aren't always meant to be used together in the same step. Here's how to tell them apart and choose the right one for your skin.

What Niacinamide Does

Niacinamide (vitamin B3) is a gentle, multitasking ingredient that helps regulate oil production, refine the appearance of enlarged pores, and support a stronger skin barrier. The Ordinary's Niacinamide 10% + Zinc 1% is especially popular with oily, acne-prone, and congested skin types, since the added zinc helps balance excess sebum.

What Vitamin C Does

Vitamin C is an antioxidant that helps brighten dull skin, fade the look of dark spots, and support your skin's defence against environmental stressors like pollution and sun exposure. The Ordinary offers several Vitamin C formulas, from lightweight suspensions to more stable derivatives, so there's an option for both sensitive and more experienced skin.

Key Differences

• Best for oil control and pores: Niacinamide
• Best for brightening and dark spots: Vitamin C
• Best for sensitive, reactive skin: Niacinamide (generally gentler)
• Best time to use: Vitamin C works especially well in the morning, layered under sunscreen; Niacinamide is flexible enough for morning or night.

Can You Use Both?

Yes, but timing matters. Some Vitamin C formulas can be less stable when combined directly with Niacinamide in the same application. The simplest way to avoid any issues is to use Vitamin C in your morning routine and Niacinamide at night, or to apply them a few minutes apart so each product has time to absorb.

Which One Should You Start With?

If you're dealing with oiliness, breakouts, or visible pores, start with Niacinamide. If your main concern is dullness, uneven tone, or early signs of sun damage, Vitamin C is the better first step. Either way, introduce just one new active at a time so you can see how your skin responds before adding the next.
