Water-in-Oil Cream with Urea

Urea is naturally found in the skin and serves as its natural moisturizer. When skin cells become hard and dry, it exposes and unloads their water binding sites, allowing these cells to retain and absorb moisture. This mechanism is called hydrotropic solubilization and has been proven effective through independent clinical trials. Urea applied in skin alone does not feel good for most people, but with this recipe, it is coupled with other potent nutrients like polyglyceryl oleate, grapeseed oil, and polyglucose to deliver optimum moisture. Feel its silky smoothness when you apply this lotion!
