Korean prices for skincare - was I given a fair price?

I was recently in Korea on business from abroad. and because I had very little time I consulted with a few dermatology clinics to address some skin issues I had.  I didn’t have much basis to negotiate as I didn’t know the going prices of things there, my feeling is I was overcharged because I was a foreigner. My question is, was I given a fair price?  Here is what I got done: Laser toning: Revlite laser and  Ventige laser (both full face) to address melanocytes and blood vessels (overall tone of skin). Fraxel Etwo on acne scars on the face (not whole face just cheeks where scars were). Lastly, rejuran injections to make skin look healthier.  I paid a total of 1,900,000 won.  Can you tell me if I was overcharged and if so what the rate should have been.  Also, if you know of any other clinics that do the same procedures for cheaper can you let me know. Thanks
