Canderm powder contains a combination of antifungal medicine, clotrimazole, and a skin protectant, zinc oxide. People use it to treat and prevent fungal skin infections like ringworm, Athlete’s foot, jock itch and pityriasis Versicolor (a fungal infection that causes small patches of discoloured spots on the skin). Canderm powder is also used to absorb excess moisture or perspiration in areas of skin folds to reduce the risk of fungal infection and friction rashes.
