What is niacinamide?

Niacinamide, also known as nicotinamide, is a form of vitamin B3. This is an essential nutrient for the function of the skin.

It naturally occurs in certain foods, such as meat, fish, milk, eggs, cereals, and green vegetables. A synthetic form of it can also be found in various skincare products, including moisturisers and serums.

Niacinamide benefits: What is niacinamide good for?

Niacinamide can offer many benefits for the skin. Here’s a breakdown of some of the main niacinamide benefits:

Has hydrating and soothing properties

Niacinamide can enhance the lipid barrier’s function in the skin to lock in moisture and keep skin hydrated. Keeping skin hydrated helps keep the skin looking smooth and can promote a healthy-looking complexion. It can even help in the management of dry skin conditions, such as eczema, by locking in skin-moisture.

This B3 vitamin also has soothing properties that can help reduce skin irritation and redness. This makes it suitable for soothing irritation caused by exfoliants like retinol and glycolic acid.

Improves the appearance of dark spots

Niacinamide can help brighten skin tone and lighten dark spots.

Reduces fine lines and wrinkles

Due to its antioxidant and hydrating properties, niacinamide can help protect the skin and aid in its recovery from stressors, such as sun damage. Therefore, its topical application could help to improve the appearance of fine lines and wrinkles.

Helps with oily, spot-prone skin

Excess sebum or oil can lead to blocked pores, breakouts and blemishes. Through its actions in the skin, niacinamide may help reduce the production of sebum, and can offer a way of helping manage oily, spot-prone skin for those with more sensitive skin.

Helps protect against premature ageing

Niacinamide can help to combat internal and external stressors that contribute to premature ageing of the skin. This includes the effects of the sun’s UV rays.

How long does niacinamide take to work?

Depending on the formulation of the skincare products used, it can take a few weeks before you start to see any significant results.
