>After 4 months, do you see any changes at all?
Hardly. You'll more likely notice emotional and libido changes during that time. If your skin's in bad shape it might clear up and but most of the actual physical changes of HRT do not even start to occur until 6 months.
It's just photo lighting and angles
looking good OP
there are a few subtle changes in your face so far. you will really notice the difference in your pre pics compared to the ones you will take in the 6-12 month area.
but so far so good you look like you passed even before hrt.
hope everything keeps going well for you
