System Verdict
This is a very solid hydrating toner, not a miracle treatment. The efficacy score lands at 4.0 because the formula is genuinely well-built for hydration and soothing—glycerin-like humectancy from butylene glycol and betaine, barrier support from panthenol and sodium hyaluronate, plus calming agents like centella, licorice, beta-glucan, and copper tripeptide-1. But it is still a toner: most of the potentially interesting actives are likely present at modest levels, there is no strong acid system or high-dose treatment active, and the vitamin C derivative / peptide are unlikely to behave like a dedicated serum-level treatment here.
