When you stop using soap on your body your body will eventually buildup oils and dirt as well as germs that are not washed away with just water.
Eventually that oil, dirt, germs etc will cause skin irritation and skin breakdown.
It's okay to go without soap for a few days unless you're really dirty but you should use soap mostly when showering or bathing to stay clean and to get rid of germs.
Without the use of soap the skin would become oily or dry and become infected with fungus or yeast and then bacteria.
The dirt on the skin could then cause warty growths.
When using soap on your body when bathing or showering you should also ensure the soap is rinsed off.
Leftover soap and hair products can create skin irritation and blocked pores.
You could also be inadvertently causing acne if you're not rinsing the soap off well enough when bathing or showering.
This mistake is one of the most frequent bathing and showering mistakes.
If you struggle with breakouts on your back, it may be from your hair products or soap.
If you're looking for something eco friendly and sustainably made to cleanse dirt from your body, basic bar soap is best.
If you need skin hydration, serious exfoliation, or acne treatment during your shower, a body wash or shower gel might be the better choice.
Water alone can not effectively remove dirt, oils, and sweat, while soap and shower gel can help eliminate odor-causing bacteria.
Hair care can also be affected, as water-only showers may not effectively clean or remove built-up oils and residues, leaving hair feeling greasy, heavy, or unclean.
