Is no needle mesotherapy harmful for pregnant woman?

The honest answer is we don't know. In the absence of studies of safety it is best to not perform Mesotherapy during pregnancy.  Almost all cosmetic procedure should be postponed until after delivery in pregnant women. Wishing you the best of health, 

Hi An Ju,Mesotherapy is general term for a treatment that employs application of pharmaceuticals or homeopathic medications into the subcutaneous fat. In general, there are medications that are safe for pregnant women so it follows that mesotherapy can be done on provided that the substance to be used is safe for pregnant women. But for safety reasons, cosmetic procedures are best done after childbirth or after breastfeeding. Congratulations for the baby!
