Plain water cannot remove dirt and sweat completely from the face. Soap or body cleanser is too harsh for kids' face. Cool kids facial cleansing gel is a perfect choice for kids. Top skin layer function acts as skin barrier, protect skin from environment damage, bacteria and skin hydration. As plain water couldn’t removes unwanted dirt, soil and bacteria from skin so that cleanser can made better condition but it  will also weakening skin barrier because surfactants in cleanser cause significant skin irritation, interact strongly with skin proteins and alter lipid barrier function cause skin damage, dry, irritate, itches and bacteria will easily invasive to the body.  Another factor that can aggravate surfactant induced dryness and irritation is the pH of the cleanser. High pH can increase top skin layers swelling and alter lipid rigidity. Thereby cleansers with mild surfactants(minimize surfactants damage to skin and replenishing the skin lipids lost or deliver beneficial agents such as skin lipids and humectants under wash conditions) and neutral or acidic pH, close to normal top skin pH 5.5 potentially less damaging to the skin.
