What is niacinamide?

My research led me to The Ordinary's Niacinamide 10% + Zinc 1% serum, a targeted serum that helps reduce the appearance of skin blemishes and congestion. As its name suggests, niacinamide, also known as Vitamin B3, is the serum’s star ingredient.

A powerful ingredient that reduces inflammation and improves the skin’s barrier function, it helps diminish the look of redness and blemishes, leaving skin looking smooth and healthy.

Who should use niacinamide?

According to Deciem, this lightweight serum is suitable for use on all skin types, though they do note that it is not a treatment for acne.

It can be used as part of your morning and evening skincare routine, but if you're unsure about how a new ingredient will affect your skin, you should always try a patch test on your wrist before applying anything to your face.
