I was previously unfamiliar with phytoestrogens (or so I thought) until I did a bit of research. From what I found, there doesn't seem to be much proof that phytoestrogens (such as soy bean seed extract) work in cosmetic form. The one potentially reputable source I found suggests that it may be useful for post-menopausal women. Well, I don't know if you've seen a photo of me, but I am certainly not in that demographic. VENeffect does not mention post-menopausal women on their website at all, which makes the premise of their products misleading. 

To be honest, the only reason I will continue to review these is because I can give you an ingredient breakdown and an overall idea of what the smell, texture and absorption is like.
