It is safe to undergo an IPL laser procedure after pregnancy but there is one issue to think about. It is not uncommon for women to experience an increase in brown pigmentation during pregnancy. This is related to hormonal changes during the pregnancy and is called melasma. Unlike brown spots that are caused by sun exposure, which are easily treated with IPL, the result of IPL on melasma is less reliable. Approximately 30% of melasma patients will find improvement with IPL, 30% will see no change, and 30% of melasma patients will have worsening of their pigmenation with IPL treatment. For this reason, we counsel caution in using IPL immediately after pregnancy
