FAQs

What is Niacinamide?

Niacinamide, also known as vitamin B3, is a water-soluble vitamin that is present in many of the foods we eat such as eggs, cereals, green vegetables, and milk. It’s also naturally produced by the body and used in vital functions such as digestion. When applied topically it also has numerous benefits to the skin.

Niacinamide Skin Benefits

Niacinamide, known for its calming and anti-inflammatory properties, is considered safe and suitable for all skin types. This versatile ingredient is especially beneficial for those with oily, acne-prone, or eczema-affected skin. In the following sections, we delve into the myriad benefits niacinamide offers and explore its positive effects on the skin.

Reducing inflammation

Niacinamide has an anti-inflammatory action on the skin which makes it very beneficial for skin concerns that are caused by inflammation such as acne, excess oil, and eczema.

Minimises pores

Niacinamide is clinically proven to help reduce ageing signs and this includes minimising the appearance of pores. As it also helps to reduce and control sebum production, you should also see an improvement in congestion.

Strengthening the skin barrier

Niacinamide helps the skin to produce essential lipids which are essential for keeping the skin barrier strong. This also helps the skin to retain moisture and improve its overall texture.

Regulating oil production

Skincare formulated for oily and acne-prone skin often contains exfoliating ingredients that dry the skin out. The skin responds to this by producing more oil to compensate and the cycle continues. Niacinamide can help with this by repairing the skin barrier and helping it to produce essential lipids needed to regulate oil production. As such, niacinamide can be very beneficial in reducing and calming breakouts and oil-related skin concerns.

Improving texture

Due to the way niacinamide improves the skin barrier, increases lipids and important proteins such as keratin, it can be very effective at improving overall skin texture.

Brightening the skin

Niacinamide helps to reduce dark spots and provide protection against oxidative stress – both factors that help to brighten the complexion and improve radiance.


Niacinamide is a powerful ingredient that can improve skin’s health and appearance.
