Niacinamide is the amide form of vitamin B3 and arguably the most evidence-backed active in mainstream skin care, with decades of published research behind it. It earned its place in our post-run formula the boring way: by working, gently, in study after study.
The Science of Niacinamide
Reviews in the Journal of Cosmetic Dermatology document niacinamide's ability to support the skin barrier, including stimulating the skin's own synthesis of ceramides and other barrier lipids, and to improve hydration by reducing water loss[1]. Controlled clinical work has further shown improvements in the look of redness, blotchiness, and skin texture with regular topical use[2].
Map that onto a runner's skin after a long effort, dehydrated, friction-stressed, visibly flushed at the waistband and bra line, and the fit is obvious. Niacinamide calms the look of that irritation while reinforcing the same barrier the ceramides in the formula are rebuilding. It is water-soluble, stable, and famously well tolerated, which also makes it one of the safest actives to use daily.

Inside the Aura System
Niacinamide is the calm in Aura Recovery, formulated at a meaningful concentration alongside ceramides, panthenol, and centella for the post-run window. Prevention before the run belongs to Aura Full and Aura Ultra.
For the Long Distance Runner
One study finding matters most to distance athletes: niacinamide stimulates skin's own ceramide production. A high-mileage week is a running argument between barrier depletion and barrier rebuild, and an ingredient that tips skin toward producing its own repair material earns its concentration honestly. Pairing it with an elite anti-chafe balm for long distance runners on the front end makes the two halves of the system meet in the middle: fewer insults during the run, faster restoration after it.
The gentleness is the other half of the case. Post-run skin does not need aggressive actives; it needs proven, tolerant chemistry, and few ingredients carry more proof.
Frequently Asked Questions
What does niacinamide do for skin?
It strengthens the skin barrier, supports hydration, and visibly calms redness and uneven texture, findings replicated across decades of clinical research at everyday concentrations.
Is niacinamide good after running?
Yes. Post-run skin is dehydrated and friction-stressed, which is exactly the state barrier-supportive, redness-calming ingredients address. Applied within the hour after finishing, it works alongside ceramides during skin's most receptive window.
Can I use niacinamide every day?
Niacinamide is among the best-tolerated actives in skin care and is routinely used daily. Aura Recovery doubles as an everyday hydration cream on rest days for that reason.
