The reality of your question is that while we all know this can be safely done while pregnant, we all would recommend that you wait until after pregnancy to have IPL treatments, unless there is a medical reason to have it done, which there is not here. There is no formal studies that ever have been done on pregnant women with IPLs and although we have all probably treated pregnant people with these devices, the best bet is to wait.We also would not recommend using a topical medicine with hydroquinone either – again, these studies have not been done. Having said that, there are several cosmeceuticals that can be used during pregnancy that can have an effect on pigment – one of these is Neocutis’ Perle. This product has several actives in it that can affect the pigment pathway and because it only has actives in it, can be used at any time. But stay away from lasers and light.
