What is "shaving foam"?

Shaving foam is a product used for shaving that creates a rich, foamy lather when applied to the skin. It helps to soften the hair, moisturize the skin, and provide a smooth surface for the razor to glide over, resulting in a close and comfortable shave. The foam also helps to protect the skin from irritation and razor burn, leaving it feeling refreshed and moisturized after shaving.
