The high concentration of 92% snail secretion filtrate in the COSRX All In One Cream is formulated to facilitate skin regeneration. Snail mucin contains glycoproteins, hyaluronic acid, and glycolic acid, which are known for their moisturizing, exfoliating, and cell-renewal properties. In scenarios of minor skin irritation or dryness, this formulation aims to replenish lost moisture and support the skin's natural barrier function, potentially reducing redness and improving texture. Clinical studies on snail mucin derivatives often show improved hydration levels and a reduction in the appearance of superficial scars or post-acne marks within 4-6 weeks of consistent use.

The COSRX Advanced Snail Peptide Eye Cream utilizes a formulation with 72% snail secretion filtrate combined with peptides. Snail mucin provides hydration and supports collagen production, while peptides are short chains of amino acids that signal skin cells to perform specific functions, such as boosting collagen and elastin. This dual action aims to address signs of aging like fine lines and wrinkles by improving skin elasticity and firmness. The humectant properties of snail mucin also help plump the delicate under-eye skin, which can visually diminish the appearance of dark circles and crepiness.

With 10,000ppm (1%) of snail secretion filtrate, the COSRX Advanced Snail Mucin Gel Cleanser is designed for gentle yet effective cleansing. Unlike harsh surfactants that can strip natural oils, this cleanser aims to maintain the integrity of the skin barrier. The mucin component provides a layer of hydration during the cleansing process, helping to prevent the post-wash feeling of tightness often associated with over-stripping. This formulation is particularly beneficial for individuals with dry or sensitive skin types who require a cleanser that removes impurities without depleting key moisture.

The Advanced Snail 96 Mucin Power Essence's primary claim of maximizing skin elasticity is attributed to its high concentration of snail secretion filtrate, which is rich in hyaluronic acid and mucopolysaccharides. These components are potent humectants, drawing moisture from the environment into the skin. Increased hydration leads to plumper, more supple skin, which in turn enhances its visible elasticity. Furthermore, snail mucin is believed to stimulate fibroblast activity, promoting the synthesis of collagen and elastin, the proteins that provide skin with its structural support and resilience against deformation. The lightweight, fast-absorbing nature ensures these benefits are delivered efficiently.
