What it is
Effects: Cleanses, sterilizes, and disinfects the skin. Prevents body odor, sweat odor, and acne. . Persimmon tannins combat the cause of body odor: The odor of body odor is caused by a compound called "nonenal," which is produced when fatty acids in sebum oxidize or bacteria on the skin decompose. Persimmon tannin, the active ingredient in Dad's Soap, has the unique ability to bind with odor-causing compounds and convert them into other substances. This effect is believed to be effective in targeting odor-causing substances and breaking down and eliminating the odor at its source. It also contains moisturizing ingredients, making it ideal for daily skin care. . Relieves back acne: Dad's Soap's active ingredient, isopropyl methylphenol, has antibacterial properties. It kills acne bacteria and the Malassezia fungus that causes back acne, keeping your skin clean. Despite its cute name, this reliable soap contains ingredients that get the job done. . Carelessness is also a big enemy for the middle generation: Middle-aged oily odor, which appears in people in their 30s and 40s and peaks in people in their 50s, is caused by a compound called "diacetyl." It occurs when lactic acid in sweat is broken down by staphylococcus bacteria. Pay particular attention to the area around the back of the head and the back of the neck. Just because you're young doesn't mean carelessness is your biggest enemy. Dad's soap can also be useful as a preventative measure.
