When Iona first got the blemish, she was irritated, but not too concerned.
She assumed the pimple was the result of a few late nights or some junk food — nothing out of the ordinary.
"But [after a while] I realised that I consistently had this one really bad pimple, and then consistently had a couple of really bad pimples," Iona said.
The acne came as a surprise for Iona, who didn't have a history of acne.
"I never had any problems with acne growing up," she said.
