I've not noticed much change in the age I look as a result of T itself.

People say it makes you look older but I think that's just the effect of looking less neotonous - women tend to look more neotonous on the whole than men in the facial region. Less bony, bigger looking eyes etc.

Since I always looked young even when I was 35, I still do. The effect is being called "young man" or assumed to be in my twenties constantly, though I'll be 40 in 8 months. Not that I have a problem with that. Let them all think I'm horribly green and unwordly. Haha.
