Hi Supergirl,
There is definitely a purpose and result from doing HRT, and it goes way beyond your face. That said, you will see some changes in your appearance. As others have mentioned, it doesn't change bone structure, or do much for decreasing facial hair, but it will give you softer skin, and increase subcutaneous fat. Body hair will be decreased, as will skin oil. Your actual body odor will change. And that's just what it does for you physically. Emotionally and psychically, the changes can be profound.
But yes, your doctor is clueless.
With kindness,
Terri
