Is it permissible to inject the face with plasma for the purpose of radiance and adornment for the husband, not for treating wrinkles, due to facial pallor resulting from pregnancy and childbirth, knowing that one wears the niqab?

Cosmetic injections for the purpose of seeking beauty and increasing attractiveness are impermissible. However, they are permissible if intended to remove a defect or harm, with the aim of restoring the matter to its usual state. If the pallor of the complexion and the emaciation of the face due to weight loss and repeated pregnancies have exceeded the normal limit, then there is no objection to these injections to remove this defect.
