In my experience -

Things Estrogen itself does: Smooth skin Facial fat distribution (still up to you to shape eyebrows and exfoliate and such) Reverse balding that took place no more than one year before starting Give you the ability to cry and feel more emotions Improves blood pressure + cholesterol

Things fully nuked T + DHT does: Nukes body hair Nukes malebrained sex drive (random erections) Stops further male aging

Things neither do: Make boobs grow Change body shape at all Get rid of facial hair Make upper body any less wide Make you any shorter Just in general make anything smaller Change voice at all
