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”.

FAQ for Niacinamide or Vitamin C

Yes, niacinamide and vitamin C can generally be used together in a skincare routine. They work differently, with niacinamide supporting the skin barrier and vitamin C providing antioxidant and brightening benefits. If you have sensitive skin, introduce one product at a time.

Both can help improve the appearance of pigmentation and uneven skin tone, but vitamin C is particularly valued for its brightening and antioxidant properties. Niacinamide can also help reduce the appearance of uneven pigmentation by supporting the skin barrier and regulating melanin transfer.

Niacinamide is generally suitable for daily use, either in the morning or evening. However, individual tolerance can vary, so it is best to follow the product's recommended usage and introduce it gradually if you are new to the ingredient.

Vitamin C is commonly used in the morning because of its antioxidant properties. It can be followed by moisturiser and broad-spectrum sunscreen. However, some formulations can also be used at night, depending on the product instructions.

Vitamin C is widely used in anti-ageing skincare because of its antioxidant properties and role in supporting collagen formation. Niacinamide can also support overall skin health and the skin barrier, so both can have a place in an anti-ageing routine.
