Mesotherapy involves the administration of various substances (drugs, vitamins, plant extracts, homeopathic agents ...) by multiple subcutaneous or intradermal injections, usually for cosmetic or slimming purposes, also to treat pain, venous insufficiency, androgenic alopecia and other ailments. There is no evidence on the effectiveness of this practice. Moreover, among the few existing publications in scientific journals, most of them talk about adverse effects, such as infections, skin allergies and others. At latest update no published data on their compatibility with breastfeeding were found. The risk for breastfeeding or the breastfed infant depends on the product which is injected under the skin, as it has been shown a systemic absorption and therefore the medication could be excreted through the breast milk.
