Chiang Mai is a place of many ancient temples but it does not have the fountain of youth. What it does have, however, are several beauty centers that offer face lifting services. It's in this procedure combined with a healthy lifestyle that you can have that youthful beauty. There are also more none invasive procedures like thread lifting
if this is more your style. Either way, Chiang Mai may not have the fountain of youth but it does have a good alternative for it.
