no i think it's the androgen hormones like testosterone. i've been drinking a lot of soymilk which i mix with some tumeric and my skin's looking great overall. if you see women with huge natural breasts, they will usually have clear skin unless they have some unhealthy habits like smoking, bad diet ad such. i'm guessing these women have high-estrogen levels. i did read here that some studies have shown a high soy intake may cause mental impairment and an elevated risk for alzheimer's disease. so i'm bit more worried about it now though i still drink a lot of soymilk.
