The best advice I got for dealing with adult acne

I moved to New York when I was 25 and within two weeks of touching down at JFK airport, I had the first signs of adult acne.
I wasn’t sure if it was the stress of moving country — having to find a new job and apartment, organising a social security number and a bank account, all while trying to navigate a new city and a rather chaotic transport system — or if it was the increased levels of hormones in the food I was eating that had caused this flare up, but it couldn’t have happened at a more inopportune time.
