Comparison to Natural Biological Processes

The human body possesses its own systems for managing “toxins” and maintaining foot health. The skin naturally sheds dead cells through a process called desquamation, while the liver and kidneys handle internal detoxification. A baking soda soak does not “draw toxins” out of the body through the skin, as the skin is a protective barrier rather than an excretory organ for metabolic waste. Compared to the body’s natural pH regulation, a baking soda soak is an external intervention that temporarily alters the skin’s surface environment rather than assisting with internal biological cleansing.
