System Verdict
A solid, sensible niacinamide serum that actually earns its keep. The efficacy score is driven by a meaningful 5% niacinamide position near the top of the list, supported by hydrators and soothing ingredients like sodium hyaluronate, hydrolyzed hyaluronic acid, oat extract, and propanediol; the score is held back from the top end because the rest of the formula is mostly support infrastructure rather than additional high-evidence treatment actives, and the bifida ferment lysate contributes more marketing than dependable standalone clinical benefit.
