Hello, Welcome to healthcare magic. Cosmelite cream contains a steroid which should not be used for more than 6 weeks as this could lead to side effects. Generally, doctors will taper the medicine and alternately suggest a non steroid containing lightening agent. You could stop the cream and instead use a cream containing kojic acid, arbutin, liquorice and niacinamide at bedtime. This will prevent the spots from coming back. But more importantly, use a broad spectrum sunscreen every 4 hours to prevent the recurrence of spots. But using cosmelite for long term is not advised. Hope this helps you. Take care.
