Niacinamide (vitamin B3) has become one of the most popular active ingredients in skincare, and unlike many trendy ingredients, it has substantial research backing its benefits. It is remarkably well-tolerated, compatible with nearly every other skincare ingredient, and addresses multiple skin concerns simultaneously.
What It Does
Strengthens the skin barrier by boosting ceramide production. Reduces pore appearance by regulating oil production. Fades dark spots and evens skin tone by inhibiting melanin transfer. Reduces redness and inflammation. Improves skin texture and smoothness. May reduce fine lines by supporting collagen production.
Effective Concentrations
Research shows benefits at concentrations of 2-5%. Higher concentrations (10%+) are available but may cause irritation in sensitive skin without proportionally better results. A 5% niacinamide serum is the sweet spot for most people.
How to Use It
Apply after cleansing, before moisturizer. Works well both morning and evening. Can be layered with hyaluronic acid, retinol, vitamin C, and SPF without conflicts. One of the most versatile actives you can add to any routine.
Pairing with Other Ingredients
Niacinamide + retinol: niacinamide mitigates retinol irritation while both address aging concerns. Niacinamide + vitamin C: despite old myths, modern formulations work well together. Niacinamide + hyaluronic acid: hydration plus barrier support. Niacinamide + salicylic acid: oil control plus pore clearing for acne.
Who Should Use It
Virtually everyone. Oily skin benefits from oil regulation. Dry skin benefits from barrier support. Aging skin benefits from texture improvement and collagen support. Acne-prone skin benefits from anti-inflammatory and oil-regulating effects. Sensitive skin tolerates it well at moderate concentrations.
