What did R’ Moshe Feinstein zt”l have to say about cosmetic surgery? Is there any halachic problem with it and if so, what is it?
R’ Moshe Zt”l in CH:M 2-66 was dealing with the question, is it considered wounding oneself to undergo cosmetic surgery. He says that it isn’t considered injuring oneself because it’s part of a positive process, therefore he permits a woman to have plastic surgery. He does not discuss whether it is permitted for men. The issue would be lo tilbash. Please see the following links, where this was discussed. https://dinonline.org/2017/05/01/nosejob-for-men/
