What does niacinamide do for skin?
Niacinamide is associated in published research with barrier support and with the appearance of pores, redness and uneven tone. MIRU frames it by what is visible, not as a treatment or cure.
Can I use niacinamide every day?
Niacinamide is generally well tolerated and is commonly used daily, in the morning or evening. As with any active, introduce it on its own first and see how your skin responds.
Does niacinamide suit sensitive skin?
It is typically considered low-irritation and is often chosen for sensitive, oily, combination and dry skin. If your skin is reactive, patch-test first and add one new product at a time.
