Shampoo burn on child's face

My 11 year old son applied shampoo thinking it was facial winter cream on his face. This has caused a chemical burn on his face so there's a dark mark.  At the school clinic the doctor applied Caladry.  It's now three days and the skin is peeling off naturally and slowly. He doesn't feel any pain.  Should we still see a dermatologist?

Burns to the face:
The face has a very rich blood supply which allows it to heal very well.  We in burn care will say that the face is a privileged area.   Caladryl is typically used for thing like poison ivy, etc.  Typically for faces you can apply bacitracin or a triple antibiotic ointment.  You want to stay limited to clear agents.   The skin will initially be somewhat hyperpigmented as there is increased blood flow in the area and this improves with time as the wounds continue to heal.
