PrinceofCats....many women both in adolescence and then later in life, during menopause, use the topical application of herbal creams that act as natural hormone stimulants/balancers to treat the effects of the hormone imbalance....hair growth, dark spots, etc....the application of these treatments goes right into the blood stream and, over time, affects the bodies reaction...so I'm not suprised that the use of soy in your moisturizer/lotion has an affect, as people before me have said....
My mother as a young girl used cortico-steroid creams topically to treat excema.....30 years later she is now seeing results of this and has to treat a hormone imbalance that started to be caused so many years ago....doctors assured her, as well as many others, there were no long-term effects from these creams...and sure enough....the sensitivity to hormone imbalance has even been passed straight down to me...
So yes, mjfan, I'd say its entirely possible...
