Mycoderm is a combination of Benzoic acid, Salicylic acid, Menthol and starch.

Benzoic acid helps prevent infection caused by bacteria and fungi.
Salicylic acid helps the body shed rough or dead skin cells.
Benzoic acid and salicylic acid topical (for the skin) is a combination medicine used to treat skin irritation and inflammation caused by insect bites, fungal infections, or eczema. It works by changing the internal pH of microorganisms to an acidic state that is incompatible with their growth and survival.
