Hello dear melalite cream causes irritation. It is quiet common with it.
You should not have kept it applied for night. Actually initially it should be applied for 2 hours and then washed.
Any way nothing to worry. Stop applying the cream now. Use mometasone
cream once in night for 7 days. Apply and keep it over night.
You will get relief.
After 7 days you can start using melalite. Better take melalite xl.
