My son runs a business at home utilizing 3D printers. He washes his hands and the printer bed plates constantly throughout the day. Using regular soap made the skin on his hands, annd particularly his knuckles, dry, crack, and even bleed at times. I researched soap options, and bought a few tallow bars from Health y Sol as well as several others for him to try. He much preferred Health y Sol’s soaps, and thus we now buy in bulk and keep it throughout our home. He uses it in the shower as well as it helps his sensitive skin in general. His hands no longer have issues with becoming overly dry despite the same amount of washing.
