I don't recommend or like homecare IPL units. First, they are much less powerful than physician office machines, which makes people overuse them and burn themselves, quite often. Second, they come with no training, which means people often use them incorrectly resulting in issues and severe damage. And finally, their instructions are certainly lacking, or you wouldn't be asking this question! IPL is not recommended for pregnant women. While there is absolutely no evidence to show it does any damage to you or the fetus, we don't test machines on pregnant women because of the mere possibility of harm. So it's best to not use a homecare IPL while you are pregnant.
