If you simply castrate yourself, your face will not feminize, although the hair growth will be worse. Estradiol is not just a blocker, it acts on the estradiol receptors and feminizes you. Unfortunately, I do not have photos of my face before estradiol (I have 2.5 months), but after 5 months I saw noticeable changes in my face. The fat tissue on the face is redistributed, the eyes become more open, and your appearance is more harmless and childish. I like androgyny, so I do not mind such changes.
