I want to have the halo treatment done before I get pregnant (after my first baby I developed lots of hyperpigmentation/melasma). My appointment is booked for 2 days after my next ovulation date, which means I could technically be pregnant at the time of my appointment. If I am pregnant at the time of my appointment: could this harm the baby in any way? And should I be concerned about hormonal changes to my skin and their affect on the treatment results if I am pregnant while receiving treatment?
