stratum corneum
The "bathtub ring" on the skin is primarily associated with the stratum corneum, the outermost layer of the epidermis. This layer consists of dead, flattened skin cells that can accumulate residue from water, soaps, and other substances, creating a visible ring. When skin is submerged in water, the stratum corneum can absorb moisture, leading to the formation of this ring upon drying.
The ring around the bathtub is caused by soap scum an dirt. The ring can be washed off using bathroom cleaner.
A bathtub ring forms from the residue left behind when water evaporates, leading to the concentration of soap scum, body oils, and minerals along the water line. These substances then combine to create a visible ring around the tub. Regular cleaning can help prevent the buildup of this residue.
