Niacinamide, also known as Vitamin B3 and Nicotinamide, has many skincare benefits. Firstly, it regulates sebum production in the skin, which in turn reduces blemishes and visible pore size. It also reduces facial redness by improving microcirculation, which means moving the blood inside the capillaries away from the face to reduce visible redness. It also has the ability to strengthen the natural lipid barrier of the skin by encouraging ceramide production (the building blocks which seal our skin cells together), which in turn increases the hydration within the epidermis. Lastly, niacinamide works to help reduce hyperpigmentation by blocking melanin from being deposited on the skin cells.
