{"type":"firestarter.listing","listing":{"id":"lst_2vNkk7cs","product_name":"Immersion™","category":"serum","description":"About This Formula\n\nWater alone does not hydrate the skin. This is one of the most important and most consistently overlooked distinctions in skin health — and it changes everything about how dehydration is understood and addressed.\nFor water to reach the skin's cells and remain there, it needs conductors — humectants that draw moisture toward the outer skin layers, and the mineral and amino acid environment that determines whether water reaches the cells that need it or passes through without restoring them. Drinking more water helps. But for the skin specifically, topical humectant delivery — applied to damp skin so the humectants have surface moisture to draw inward — is the most direct cellular hydration intervention available.\nImmersion was formulated as that intervention. Not a moisturizer. Not an oil. A concentrated humectant and peptide serum that addresses the water dimension of skin health — the cellular dehydration that no lipid-rich cream resolves because it is a water condition, not a lipid one. Lightweight, fast-absorbing, and formulated without the risk of congestion.\nWith regular use, the skin is steadily replenished with what it needs to maintain a consistently hydrated state — one of the six skin states Klur recognizes as foundational to optimal skin health.\nEsthetician developed. Made without parabens, fragrance, phthalates, or dyes. Sustainably manufactured in the United States.\n\nThe Formulation\n\nImmersion is built around a layered humectant system — Beta-Glucan, Sodium Hyaluronate, Hydrolyzed Sodium Hyaluronate, Sodium PCA, and plant-based Cassia Angustifolia polysaccharide — each drawing and binding moisture at different depths of the skin's outer layers simultaneously. Sodium PCA is a direct component of the skin's own Natural Moisturizing Factor — the amino acid-derived humectant system the skin produces internally and that daily cleansing consistently extracts. Immersion returns what the routine takes.\nThree signal peptides — Acetyl Hexapept","images":["https://cdn.shopify.com/s/files/1/2234/0215/products/Klur_IM-OnGray.jpg?v=1545274460"],"price":70,"currency":"USD","in_stock":true,"inventory_qty":9999,"dynamic_pricing":false,"listed_at":"2026-06-18T20:44:49.827Z"},"share_url":"https://firestarter.network/l/lst_2vNkk7cs","purchase":{"summary":"Live product listing on the Firestarter agent commerce network.
