According to Dr Ritika Shanmugam, Founder and Chief Dermatologist, Director of Dr Ritika Shanmugam Skin Hair Aesthetics, “Both these ingredients can help improve skin health over time, but the choice largely depends on your skin type and concern.”

What does niacinamide do for your skin?

Niacinamide, a form of vitamin B3, supports the skin barrier and helps regulate oil production. Dr Shanmugam explains that it works by inhibiting melanin transfer and can help reduce the appearance of pores, acne and redness while calming inflammation.

Because of its barrier-supporting properties, niacinamide can be a useful option for sensitive and acne-prone skin. It can also be used during the day or at night.

What does vitamin C do?

Vitamin C is a powerful antioxidant that helps fight free radicals and works by inhibiting the tyrosinase enzyme involved in melanin production. It is commonly used to address pigmentation, uneven skin tone and dark spots.

The dermatologist also notes that vitamin C can support collagen formation, making it a popular ingredient in anti-ageing skincare. However, it can irritate sensitive skin, so it should be introduced cautiously. It is generally best used alongside sunscreen during the daytime.

Niacinamide vs Vitamin C: Comparison table

Niacinamide	Vitamin C
Supports the skin barrier	Provides antioxidant benefits
Helps control excess oil	Helps brighten the appearance of skin
Can improve the appearance of pores	Helps improve uneven-looking skin tone
Often suitable for sensitive skin	Can be more irritating for some people

Niacinamide or vitamin C: Which should you choose?

The answer depends on your skin's needs. If hydration, oil control, barrier support and reducing the appearance of pores are your priorities, niacinamide may be the better choice. If you're primarily looking for brightening, pigmentation care and anti-ageing benefits, vitamin C may be more suitable.

The two ingredients can also be used together. Niacinamide can support and calm the skin, while vitamin C targets uneven-looking skin tone and provides antioxidant benefits.

Lastly, Dr Shanmugam says, “Choosing between niacinamide and vitamin C comes down to your skin type, tolerance and specific concern, rather than which ingredient is universally better”.
