Cosrx Hydrium Moisture Power Enriched Cr is a moisturizing cream that contains key active ingredients such as Vitamin B5 (panthenol), sodium hyaluronate, and allantoin. Panthenol, a provitamin of B5, is known for its moisturizing and anti-inflammatory properties. When applied topically, panthenol is converted to pantothenic acid, which plays a crucial role in enhancing the skin barrier function and promoting wound healing. Sodium hyaluronate, a salt form of hyaluronic acid, is a potent humectant that can hold up to 1000 times its weight in water. This ingredient helps to hydrate the skin by drawing moisture from the environment and maintaining optimal hydration levels. In addition, allantoin is a soothing agent that helps to calm irritated skin and promote cell regeneration. The pH of COSRX Cosrx Hydrium Moisture Power Enriched Cr is optimized to be compatible with the skin's natural pH level, which is around 5.5. This ensures that the cream is gentle on the skin and minimizes the risk of irritation. The viscosity of the cream is designed to provide a luxurious and smooth texture that can be easily absorbed by the skin without leaving a greasy residue. This allows for optimal penetration of the active ingredients into the skin, maximizing their effectiveness.
