At last January we would have started round the same time. 5'10" and ~150 lbs.
I dunno, I don't see much change in the mirror but I find I get gendered appropriately when I'm wearing a hoodie, hair in a pony tail and pants. In other words, when I'm dressed like I used to dress all the time.
As has been said, laser and brow shaping help. Skin care too! I have a cleanser, an eye moisturizer and a face moisturizer as part of my nightly routine. Been helping with some of the lines on my face too! And I'm 35, with a past life as a grouchy boy. I need help on the lines front!
In all honesty though, I think the #1 best thing I can do to feminize myself is smile. Boobs help too. Love em'. Still have a lot of air in a B cup bra but these girls are mine! MINE! MINE! MINE!
Slow and steady is how it goes. I just hope she's enjoying her life as much as I!
