A wildly popular additive in Japanese skincare, isoflavone soy extract works especially well with aging female skin, specifically for premenopausal and menopausal women. Along with being a powerful antioxidant, isoflavone soy extract has phytoestrogens that work with the skins natural hormone balance to retain youthful cellular regeneration that is lost in the aging process. This restoring ingredient also improves tone and texture and combats environmental exposure. Soy-based extracts are an amazing addition to any aging care skincare regimen, but please patch test or avoid if you do have any type of soy allergy.
Isoflavone soy extract can also be taken in supplement form, but please consult your doctor before taking it.
