This little bottle of magic has a cult following within the skincare community. It is a water-thin serum containing 10% niacinamide, alongside panthentol (b5) and adenosine, which works to brighten the skin and is particularly effective when combined with niacinamide. It doesn't stop there though, the formula also packs in ascorbyl glucoside (stable vitamin c), allantoin (to soothe inflammation), hyaluronic acid and beta glucan to hydrate and phospholipids to support the skin barrier.
