I have another question that concerns the type of collagen that keeps our skin tight and youthful. What relations do estrogen and testosterone have in keeping this type of collagen high or low in our body? Does more testosterone mean less collagen and does more estrogen mean more collagen? I am just confused by things I am seeing online and would like to know what the real deal is. Even on the wiki about hrt for mtfs it says that a reduction in collagen happens as a result which doesnt make sense to me at all. I thought estrogen is supposed to support collagen growth in the skin, so with the wiki saying that collagen is reduced, does that mean that testosterone just makes more? Therefore going mtf would mean less collagen? I am confused someone please clear up the false info thanks lol
