Alcohol is not effective in removing acne, which is clinically referred to as acne, a chronic inflammatory condition that commonly occurs in the sebaceous glands of hair follicles. There are many causes of acne, but the Acinetobacter bacillus tends to play a more important role in the clinic. Alcohol applied topically is generally not able to penetrate the skin and kill P. acnes bacteria. Vitamin A ointment, or benzoyl peroxide gel, is usually used for anti-inflammatory effects. For acne patients with obvious bacterial infections, the application of alcohol for external application, alcohol can not pass through the skin to play an effective bactericidal effect, this time the general application of erythromycin ointment and other drugs applied externally. However, if the patient’s local skin is obviously broken, and accompanied by bacterial infection, the application of alcohol or iodine povine for external application can play a certain bactericidal effect.
