How long after laser is it safe to become pregnant?

There is no wait time required after laser for you to try to get pregnant. Also, there should not be any risk of laser treatments affecting your chances for getting pregnant. It is difficult to predict how pregnancy hormones will effect your skin. If you remain concerned, I recommend following up with your OB/GYN about your intended treatments. For sun damage, I recommend a combination of lasers with microneedling/prp. See an expert. Best, Dr. Emer

There is no time range after laser when you can be pregnant. There is no side effect of lasers towards the ovarian function. Pregnancy hormones can affect the skin though. 

Thanks for your question!  You would be fine getting laser treatment before you become pregnant, and there are no strict guidelines or waiting periods if you become pregnant shortly after a laser treatment.  Laser treatment on the face should not affect your hormones or anything to do with pregnancy, but you would not want to take any chances during pregnancy, or while nursing, in case your hormones are unsettled.
Best of luck!
