It is not advisable to use Cosmelite while treating an active fungal infection. Cosmelite contains ingredients like hydroquinone, tretinoin, and a mild corticosteroid, which can irritate the skin and suppress local immunity, potentially worsening the fungal infection. You should pause Cosmelite use until the infection has fully cleared. Continue applying Fungicros as directed by your doctor, and once the fungal infection resolves, your dermatologist can guide you on when and how to safely restart Cosmelite to avoid irritation or recurrence.
