In The Name of Allah, The Most Merciful, The Bestower of Mercy.

Imam Abdul Aziz Bin Baz, may Allah have mercy upon him, was asked: “The correspondence as follows was sent by our brother Ismaa’eel Al-Bashir Ali Sudani, working in Qatar. Our brother has three questions. In his first question, he asks about Islam’s ruling on cosmetic surgery?”

The response:

This matter requires (detail) clarification: If a surgical procedure does not alter anything that Allah has decreed to remain as it is (i.e. its natural state), then it is permissible. For instance, if the beautification neither involves tattooing on the face of a person nor the amputation of a body part, but rather, it is for a face-lift or body enhancement, or to reshape a deformity, such as a deformed hand, a leg, or reshaping a deformed nose, there is no harm in this; or teeth that have some defect, such as uneven lengths or misalignment, or removing dark spots on the lips, or something that can be removed to attain a fine appearance without opposing Allah’s command in anything of that, then there is no harm. The Prophet, peace and blessing of Allah be upon him, prohibited tattooing and hair extensions but did not forbid beautification.

Also, if there is a growth on the hand or foot, it is permissible to remove it if a doctor determines that the procedure poses no risk. Similarly, if there is a tumor on the face or hand that can be treated, there is no harm in that, or if there are dark spots on the body or face that can be treated. There is no harm in all this because it is beautification; it does not oppose Allah’s command. [Paraphrased]
