It could be. I read all about Estrogen Dominance in men (there's a difference between the sexes), and i seem to share some traits indicating that i may have one. Either way, Estrogen is the best hormone when it comes to skin and hair, no doubt, but too much or too little of it can absolutely cause issues and i still believe Estrogen can cause acne if it isn't in balance with other hormones (i once read that there is a "good" Estrogen, and a "bad" Estrogen, but i have no idea on the matter). Sebum is a good thing to have, keeps the skin young and helps delay wrinkles. However, too much of it causes acne, and too little causes dry skin as you already know. By the way, i know you are educated on alot of AAs including bica, and i was wondering if Bica could upregulate my ARs permanently ?? I already know Bica upregulates them, but if its only a temporary phenomenon then its all good, however, if Bica is going to increase my T levels 2 fold AND increase my ARs sensitivity permanently, then i would rather opt for CPA and maybe microdosing on some E2 for good skin complexion. I don't want to screw with my ARs more than my genes already did.
