After 12 weeks of rigorous testing, here’s an in-depth analysis of this Korean skincare phenomenon that’s earned over 90,000 Amazon ratings.

Formula & Science Breakdown
This hypoallergenic essence revolutionizes hydration through bio-innovative technology. Its core ingredient, 96.3% Snail Secretion Filtrate, is ethically harvested in a stress-free environment for the snails. This potent filtrate is naturally rich in glycoproteins that boost collagen, allantoin for accelerated healing, and hyaluronic acid analogs that are deeply hydrating. The clear, slightly viscous gel spreads like liquid silk and absorbs fully in seconds with zero residue, making it ideal for all skin types.
