Potassium permanganate is a skin disinfectant and cleansing agent. 
 
Indication: To treat mild pompholyx, dermatitis, eczema and fungal infections of the feet.

Infected eczema. If you have eczema with blisters, potassium permanganate can help to dry them out. Use or create a dilution of 1 part in 10,000 (1 part potassium permanganate to 10 parts water) . Add it to a basin or bath tub and soak the affected part of your body.
 
Open and blistering wounds / superficial wound. Potassium permanganate is used as a wet dressing for wounds on your skin’s surface that are blistered or oozing pus. Apply a dilution of 1 part in 10,000 (1 part potassium permanganate to 10 parts water) to a bandage and apply it over your wound. Change the bandage two to three times a day.
 
Athlete’s foot and impetigo. Potassium permanganate can help to treat both bacterial and fungal skin infections such as athlete’s foot and impetigo. For severe infections, soak your foot in a 1 part in 10,000 dilution (1 part potassium permanganate to 10 parts water) of potassium permanganate every eight hours.
