What is the use or harmful effects of soap?

Soap is primarily used for cleaning and disinfecting surfaces, including skin, by breaking down oils and dirt, which helps prevent the spread of germs and infections. However, some soaps, especially those containing harsh chemicals or fragrances, can irritate the skin, disrupt the natural skin barrier, or contribute to environmental pollution. Additionally, overuse of antibacterial soaps may lead to antibiotic resistance. It's important to choose mild, biodegradable soaps to minimize harmful effects while maintaining hygiene.
