Hi!
V.v.sorry, I did not see your msg till now and don't know if it is too late for you.

Unfortunately, you cannot book appts earlier with Dr. Shobana but you can call a day before going to check that she is not out of town at the time. Also, a month may be too little time to get the full treatment as I think each session needs a 6 wk gap....but you can certainly ask the dermatologist abt this after explaining your problem.
Someone else on this site had also recommended the following place in another post; I am reproducing what was written over there...
