Is concealing physical flaws (such as black spots after makeup removal) and undergoing surgical operations (such as a gastric bypass that caused sagging and repulsion) before marriage without informing the husband considered deception?

"The woman ought not to have concealed the darkness of her skin with cream before the 'Shar'i (Islamic legal) viewing.' However, it is not obligatory to disclose such a flaw because it does not invalidate the marriage contract. Similarly, you are not obligated to be informed about the cosmetic surgery, as it does not affect enjoyment, although informing you would be preferable for reassurance. You should not divorce her for this reason; rather, be patient with her, especially if Allah has blessed you with children through her. You may marry another if you are able to be just."
