For my first chin session, the aesthetician stayed and there were no issues. The second (on the new system), she left and it was more painful. At one point I was going to call the front desk to end it but an alarm went off. I thought she’d return but she didn’t for another five minutes. The pain eased and when she returned, she said the machine stopped with 92 seconds to complete freeze (with 6:28 on clock)? I’m wondering will it still work and should they have stayed?
