You may use Kevon Lotion (Ketoconazole) with AF-400 Tablet (Fluconazole) for a fungal infection, but only under medical supervision. Please consult your doctor first, as using oral and topical antifungals together in a sensitive area requires proper dosing and monitoring for potential side effects.

You may apply an over-the-counter antifungal cream, lotion, or shampoo containing clotrimazole, ketoconazole, or selenium sulphide as directed. Keep the affected area clean and dry, avoid excessive sweating, and wear loose clothing to reduce moisture. If the patches do not improve, spread, or recur frequently, please see a doctor for stronger oral or topical antifungal treatment.

A growing black mark on the chest should be examined promptly by a doctor or dermatologist, as it may indicate a serious skin condition such as melanoma (a type of skin cancer). Please do not attempt to treat it yourself or use over-the-counter creams until it has been properly diagnosed.
