Its been a while since I've looked at numbers, but in general, transmen tend to look younger than they are and transwomen tend to look their age. I don't think that took into account any makeup, and the surgery techniques were different. Our skin changes as we get older, loses elasticity, gets age spots etc., but from the hormone side of things, I would think that female hormones would soften transwomen's skin, thereby making them look younger.
