Niacinamide

Niacinamide (Vitamin B3) is a multitasking powerhouse in skincare. It strengthens the skin's barrier function, boosts ceramide production, and helps visibly minimize enlarged pores. It also works to regulate sebum (oil) production, making it excellent for oily skin, while its anti-inflammatory properties soothe redness and even out skin tone. It's a highly stable ingredient that plays well with others.
