Niacinamide
Good: Nice, not necessaryevidence: moderatePEER-REVIEWED 2014
A form of vitamin B3 that can help skin hold onto moisture and may take the edge off oiliness and redness. It's genuinely well tolerated, but the studies behind it are smaller and earlier-stage than the marketing suggests. If it's already in your moisturizer, great, enjoy. You don't need to buy it as a separate serum.
what the evidence says
Mechanism studies and small trials support oil-regulating and barrier effects; reviews describe the clinical evidence as preliminary.
