System Verdict
This is a hydration-and-soothing essence, not a real repair serum powerhouse. The efficacy score is solid because the formula is built around a very high snail filtrate base plus multiple proven humectants and calming helpers like betaine, sodium hyaluronate, allantoin, and panthenol, but it does not contain a true high-evidence corrective active at treatment strength, so its benefits are mainly moisturization, slip, and mild soothing rather than dramatic skin remodeling.
