COSRX Centella Water Alcohol-Free Toner

• Centella Asiatica Leaf Water (10%): Rich in active compounds like asiaticoside, madecassic acid, and asiatic acid. It acts as an anti-inflammatory agent that accelerates wound healing, stimulates collagen synthesis, and suppresses vascular redness.
• Panthenol (Pro-Vitamin B5): A highly effective humectant that penetrates into lower skin layers. Once inside, it converts to pantothenic acid to stabilize the lipid barrier, reduce trans-epidermal water loss (TEWL), and enhance cellular repair.
• Allantoin: A keratolytic compound that soothes irritation and promotes cell proliferation. It assists the skin in shedding dead cells, revealing a smoother surface while mitigating inflammation.
• Sodium Hyaluronate: The water-soluble salt form of Hyaluronic Acid. Its lower molecular weight allows it to easily penetrate the skin barrier, binding up to 1,000 times its weight in water to plumps cells and keep hydration locked in.

The Supporting Base

• Water & Butylene Glycol: Serve as the lightweight, non-greasy solvent vehicle. Butylene Glycol pulled double duty here as a slip-agent and a humectant to draw water into the upper stratum corneum.
• 1,2-Hexanediol & Ethyl Hexanediol: Preservative boosters and moisture-binding agents that ensure the sterile stability of the spray format without relying on drying alcohols or parabens.
• Betaine: An amino acid derivative that functions as an osmolyte, helping cells adapt to moisture fluctuations and maintaining structural osmotic balance.
