Does Isoflavones Skin Hydration Randomized Trial work?

The current Migaku evidence database contains 2 reusable source documents for Isoflavones Skin Hydration Randomized Trial. This answer focuses on strength of evidence and what the studies can or cannot prove. - In exploratory regression analysis limited to S-equol producers, higher urinary S-equol levels were significantly associated with improved under-eye wrinkle parameters and transepidermal water loss (TEWL) at D42. [Vijayakumar V (2025); evidence level 2] - Multivariable model adjusting for age, soy intake, phototype and their interactions confirmed that older women experienced greater improvements in undereye wrinkles and barrier function in response to increased S-equol levels. [Vijayakumar V (2025); evidence level 2] - Conclusion Soy isoflavone supplementation increased urinary S-equol concentrations and was associated with improvements in under-eye wrinkle appearance, skin hydration, and barrier function-particularly among older postmenopausal women identified as S-equol producers. [Vijayakumar V (2025); evidence level 2] - Background/objectives Soy isoflavones may benefit skin health in postmenopausal women, potentially via S-equol, a gut-derived metabolite with enhanced estrogenic and antioxidant activity. [Vijayakumar V (2025); evidence level 2] - As a result, isoflavones may promote cell proliferation [], act as antioxidants [], and exert anti-inflammatory and anti-cancer properties [,]. [Rizzo Julianne (2023); evidence level 2] Evidence levels are sorting aids, not final clinical grades. Level 1 usually indicates systematic-review style evidence, level 2 indicates randomized trials or public-health guidance, and lower levels need more cautious wording. This page is educational.
