Is it permissible for a woman to use 100% natural fruit-extracted proteins to increase the size of her breasts and buttocks with the intention of pleasing her husband and bringing him pleasure?

There is no شرعًا (religiously) impediment for a woman to adorn herself for her husband with any permissible adornment, such as wearing beautiful clothes, gold, and applying henna. There is also no impediment to adorning herself with that which helps in the growth of body parts, as long as it is within the limits of شرع (religious law) and through شرعية (religiously permissible) means and purposes, such as pleasing the husband.
