• I like using long international layovers to get aesthetic treatments at med spas.
• Many of my treatments have cost less abroad than they would've at home in San Francisco.
• Be sure to do your research and know the possible side effects of treatments before you book them.

As a travel writer, I'm privileged to take many trips...
