Sources examining whether deliberate bodily modification for aesthetic purposes is permitted under Jewish law. The sources address foundational prohibitions against self-injury, exceptions for healing, and the halakhic distinction between medical and non-medical bodily interventions.

What the sources say
The central halachic tension surrounding elective cosmetic surgery runs through the Talmudic debate recorded in Bava Kamma 91b, where the Gemara notes a tannaitic dispute over whether a person is permitted to injure himself — with one view holding that it is not permitted and another holding that it is — establishing the foundational question of whether surgical alteration of one's own body falls under the prohibition of self-injury.
The Rambam rules decisively on one side of that dispute, stating explicitly in Mishneh Torah, Laws of Injury 5:1–2 that it is forbidden for a person to injure either himself or another, which becomes the baseline halachic concern any permissive ruling on cosmetic surgery must address.
Tzitz Eliezer 11:41 is not available in text for Mekoros to read, but our research indicates that he addresses a major responsum directly weighing concerns of self-injury and needless bodily alteration against benefits such as beautification, self-esteem, and social and psychological need in that source, making it the key authority for this question.
Tzitz Eliezer 12:43 is not available in text for Mekoros to read, but our research indicates that he addresses the conditions under which elective procedures may be permitted in this companion responsum.

ויקרא י״ט:כ״ח
Leviticus 19:28
The verse forbids gashing the flesh and tattooing, which later authorities discuss when considering deliberate bodily harm and whether cosmetic cutting is comparable or distinguishable.
וְשֶׂ֣רֶט לָנֶ֗פֶשׁ לֹ֤א תִתְּנוּ֙ בִּבְשַׂרְכֶ֔ם וּכְתֹ֣בֶת קַֽעֲקַ֔ע לֹ֥א תִתְּנ֖וּ בָּכֶ֑ם אֲנִ֖י יְהֹוָֽה׃
You shall not make gashes in your flesh for the dead, or incise any marks on yourselves: I am GOD.
כתובות ע״ז ב
Ketubot 77b
In a case of a man afflicted with boils, even if his wife declares willingness to remain with him under the supervision of witnesses without secluding herself with him, the halakha does not permit her to do so, because the boils consume his flesh.
וַהֲרֵי מוּכֵּה שְׁחִין, דְּאַף עַל גַּב דַּאֲמָרָהּ ״הָוְיָנָא בַּהֲדֵיהּ״ — לָא שָׁבְקִינַן לַהּ. חוּץ מִמּוּכֵּה שְׁחִין, מִפְּנֵי שֶׁמְּמִקָּתוֹ וְקָתָנֵי!
As we learned in the mishna: Apart from a situation where her husband is afflicted with boils, because it consumes his flesh. The Gemara answers: Even so, there is a difference between these cases, as there, with regard to a man with boils, if she says: I am willing to live with him under the supervision of witnesses; that is, I will not seclude myself with him but I will nevertheless remain his wife, we leave her alone.
בבא קמא צ״א ב — ד"ה וְקָתָנֵי
Bava Kamma 91b:1
The Gemara discusses self-injury, especially the prohibition of wounding oneself, and related interpretations used in later halakhic analysis. It is foundational background for the permissibility of elective body modification.
וְקָתָנֵי: הַחוֹבֵל בְּעַצְמוֹ, אַף עַל פִּי שֶׁאֵינוֹ רַשַּׁאי – פָּטוּר! הָכִי קָאָמַר לֵיהּ: לָא מִבַּעְיָא בּוֹשֶׁת, דְּאָדָם רַשַּׁאי לְבַיֵּישׁ אֶת עַצְמוֹ; אֶלָּא אֲפִילּוּ חֲבָלָה, דְּאֵין אָדָם רַשַּׁאי לְחַבֵּל בְּעַצְמוֹ – אֲחֵרִים שֶׁחָבְלוּ בּוֹ, חַיָּיבִין. אֶלָּא תַּנָּאֵי הִיא; דְּאִיכָּא לְמַאן דְּאָמַר: אֵין אָדָם רַשַּׁאי לְחַבֵּל בְּעַצְמוֹ, וְאִיכָּא מַאן דְּאָמַר: אָדָם רַשַּׁאי לְחַבֵּל בְּעַצְמוֹ.
and it teaches: With regard to one who injures himself, although it is not permitted for him to do so, he is nevertheless exempt from any sort of penalty, indicating that the prohibition is in effect even with regard to humiliation. The Gemara answers: This is what Rabbi Akiva said to the man: It is not necessary to say with regard to humiliation, where it is permitted for a person to humiliate himself, that someone else who humiliated him is liable. But even with regard to injury, where it is not permitted for a person to injure himself, others who injured him are liable. Rather, it must be that this is a dispute between tanna’im, as there is a tanna who says that it is not permitted for a person to injure himself, and there is a tanna who says that it is permitted for a person to injure himself.
שבת ס״ז א — ד"ה אַבָּיֵי וְרָבָא דְּאָמְרִי תַּרְוַיְיהוּ
Shabbat 67a:14
The sugya on doctoring and non-medical practices of the amoraim includes discussion relevant to bodily interventions and the line between healing and prohibited acts. It forms a background sugya for later responsa on surgery.
אַבָּיֵי וְרָבָא דְּאָמְרִי תַּרְוַיְיהוּ: כׇּל דָּבָר שֶׁיֵּשׁ בּוֹ מִשּׁוּם רְפוּאָה אֵין בּוֹ מִשּׁוּם דַּרְכֵי הָאֱמוֹרִי.
With regard to the halakha in the mishna, the Gemara cites Abaye and Rava, who both said: Anything that contains an element of healing and seems to be effective does not contain an element of the prohibition against following the ways of the Amorite. There is no cause for suspicion of one who engages in their practice, gentile or Jew.
משנה תורה, הלכות חובל ומזיק ה׳:א׳-ב׳
Mishneh Torah, One Who Injures a Person or Property 5:1-2
Rambam lays out the laws of bodily injury and the obligation to compensate for injuries. This is relevant background for evaluating whether one may deliberately wound or alter one's body for cosmetic purposes.
אָסוּר לְאָדָם לַחֲבל בֵּין בְּעַצְמוֹ בֵּין בַּחֲבֵרוֹ. וְלֹא הַחוֹבֵל בִּלְבַד אֶלָּא כָּל הַמַּכֶּה אָדָם כָּשֵׁר מִיִּשְׂרָאֵל בֵּין קָטָן בֵּין גָּדוֹל בֵּין אִישׁ בֵּין אִשָּׁה דֶּרֶךְ נִצָּיוֹן הֲרֵי זֶה עוֹבֵר בְּלֹא תַּעֲשֶׂה שֶׁנֶּאֱמַר (דברים כה ג) "לֹא יֹסִיף" (דברים כה ג) "לְהַכֹּתוֹ". אִם הִזְהִירָה תּוֹרָה מִלְּהוֹסִיף בְּהַכָּאַת הַחוֹטֵא קַל וָחֹמֶר לְמַכֶּה אֶת הַצַּדִּיק:
It is forbidden for a person to injure anyone, neither his own self nor another person. Not only a person who causes an injury, but anyone who strikes in strife an upright Jewish person, whether a minor or an adult, whether a man or a woman, violates a negative commandment, as Deuteronomy 25:3 states: "Do not continue... to flog him." One may conclude that if the Torah adjures us against adding to the blows due a sinner, surely this prohibition applies with regard to striking a righteous person.
