Should I Remove Layers That Form After Applying Silverex Ointment On My Burn Before Reapplying?

Hi, i had hot tar fall on my hand, I instantly peeled it away, my skin was also peeled away with that, for 4 days it was covered with bandage, now doctor said to remove dressing and start applying SILVEREX Ointment, but after 2 days of use, it s creating layers upon layer after use, should I remove it before next application, if yes, what is the approach?
