Soy Isoflavones Skin Hydration Randomized TrialThe aim of this study is to expand upon existing evidence of the benefits of soy isoflavones in postmenopausal women with Fitzpatrick skin types I–IV, by examining the effects of a 12-week supplementation period on parameters of skin health and determining whether these effects are S-equol dependent.2Vijayakumar Vineetha (2025)S-equol status modulates skin response to soy isoflavones in postmenopausal women: results from a randomized placebo-controlled pilot trial
Soy Isoflavones Skin Hydration Randomized TrialThese analyses were performed in R v4.3.3, using thefunction for backward stepwise variable selection to remove unnecessary predictors, using AIC criteria ().-values of the linear regressions were corrected following Benjamini-Hochberg procedure to reduce the risk of type I errors.2Vijayakumar Vineetha (2025)S-equol status modulates skin response to soy isoflavones in postmenopausal women: results from a randomized placebo-controlled pilot trial

Soy Isoflavones Skin Hydration Randomized TrialThis study aims to investigate how oral supplementation of a soy protein isolate with added isoflavones (SPII) affects components of photoaging such as facial wrinkles and dyspigmentation, and skin biophysical measures such as skin hydration and sebum excretion in postmenopausal women.2Rizzo J (2023)Soy Protein Containing Isoflavones Improves Facial Signs of Photoaging and Skin Hydration in Postmenopausal Women: Results of a Prospective Randomized Double-Blind Controlled Trial.
