Antiseptic solution to hold off infections.
An antiseptic is a substance used to slow or halt the growth of microbes around living tissue in order to prevent infection. Antiseptics differ from antibiotics in that the latter is used to kill bacteria located inside the body, while the former is applied to surface wounds. Common antiseptics range from alcohol, hydrogen peroxide, iodine, and even sodium bicarbonate. Antiseptics should not be used for prolonged periods of time, or in incorrect dosages. Using too little antiseptic may entice microbes into developing a resistance to the chemicals, while using too much may cause harm to living cells in the vicinity.
