Assalamu alaykum, my question is, is it permissible for a Muslim woman to make plastic surgery to be more beautiful for her husband? Jazak Allahu khairan for your answer.

The principle is that it is legally prohibited to conduct plastic surgery with the purpose of changing one's appearance without a medical necessity. However, it becomes lawful [halal] if it is medically decided by the physician that the procedure will achieve either physical or psychological benefit especially one which affects the stability of life in general and of marital life in particular; or to remove either a congenital defect or one that occurs later in life. However, this must be done according to what is medically determined in order not to harm you.
