Niacinamide has many benefits when applied topically, as shown in studies of products containing a concentration of 4 to 5 percent. It helps to:
Brighten skin: Some studies have shown niacinamide to be a brightening aid that’s beneficial for hyperpigmentation.
Minimize appearance of pores: Clinically, niacinamide has been evidenced to minimize the appearance of pores and uneven skin after eight weeks.
Reduce visible signs of aging: Evidence indicates that niacinamide helps minimize fine lines, wrinkles, and sallowness, and improves skin’s elasticity.
Control breakouts: A powerful anti-inflammatory ingredient, niacinamide can calm swelling and redness caused by acne and help control oil production.
Boost skin barrier function: Niacinamide increases ceramide and free fatty acid levels in the outermost layer of our skin, reducing trans-epidermal water loss. (It keeps water in our skin from evaporating.)
One of our favorite things about this vitamin is its versatility. It works well with most other ingredients and gets a boost when paired with other potent antioxidants. Niacinamide also pairs well with retinoids, retinol-alternatives, and acids.
