Nicotinamide
A form of Vitamin B3 that supports skin health by improving barrier function, reducing inflammation, and minimizing pores.
Also known as: Niacinamide • Vitamin B3
Overview
Nicotinamide, also known as niacinamide, is a form of Vitamin B3. It is a versatile ingredient that offers numerous benefits for the skin, whether applied topically or taken orally. It plays a crucial role in cellular energy production and repair. Nicotinamide helps to build proteins in the skin, including keratin, and locks in moisture to prevent environmental damage. It can reduce inflammation, which may help ease redness from eczema and acne. It also has been shown to reduce the appearance of pore size and regulate oil production.
Key Benefits

It increases the production of ceramides, resulting in a stronger, healthier skin barrier and better hydration.

It can help to regulate sebum production and improve skin elasticity, which can make pores appear smaller.
