The Claim
Commercial rice-based cosmetics contain lower concentrations of calcium, magnesium, iron, zinc, and manganese than rice water prepared by optimal cold-soaking methods.
What the research says
Roughly balanced
Support and challenge are close. The picture may shift as more studies come in.
These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.
Rice water made by soaking rice in cold water has more calcium, magnesium, iron, zinc, and manganese than store-bought rice-based skincare products.
See the scientific wording
Commercial rice-based cosmetics contain lower concentrations of essential minerals (calcium, magnesium, iron, zinc, manganese) than rice water prepared by optimal cold-soaking methods, suggesting homemade rice water may be a more nutrient-rich alternative for topical use.
When rice is soaked in cold water, minerals like calcium, magnesium, iron, zinc, and manganese dissolve out of the grain and into the water. Commercial products remove these minerals during processing to stabilize the formula or extend shelf life, leaving behind less of these nutrients than what naturally comes out of rice during soaking.
What the research says
1 studyScientists found that soaking rice in cold water at home pulls out more good minerals like calcium and zinc than what’s found in store-bought rice skincare products, so homemade rice water might be better for your skin and hair.
