I'm glad it worked for you but I dare say they probably had a vested interest in prescribing that under their brand since as Amy Baron stated it, or a similar product, can likely be easily found at a fraction of the price. Buy hey, business exist to make a profit, right.
I can personally recommend this clinic if you have further need for dermatology services. Dr. Vachiraporn works at Chiang Mai Ram during the day. Going to the clinic eliminates hospital related charges, which at CM Ram add up quickly.
