Soy Lotion and Silkier Legs

In the April issue of Self Magazine In the beauty question & Answer section I came across the following:
Question- I use a moisturizer that contains soy to slow hair growth on my legs. Am I getting a dose of feminizing hormones through my skin?
Answer - You're right that soy has phytoestrogens, plant compounds that can act like the human hormone estrogen. When eaten, as in tofu, the amount your body absorbs can be significant, but "When soy is applied to your skin, the amount of phytoestrogens absorbed is minuscule and unlikely to have any systemic effects," says Jeffrey Benabio, M.D., a dermatologist in San Diego. Interestingly, the ogttoestrogens aren't what is taming hair growth: Soy also contains proteins called soybean trypsin inhibitors and Bowman-Birk protease inhibitors, which block specific enzymes in the skin that are responsible for hair pigmentation and growth. So you can be silkier safely.
