Scientific Information on Skin Moisture

Human Effect Matrix

The Human Effect Matrix looks at human studies (it excludes animal and in vitro studies) to tell you what supplements affect skin moisture
Grade Level of Evidence
Robust research conducted with repeated double-blind clinical trials
Multiple studies where at least two are double-blind and placebo controlled
Single double-blind study or multiple cohort studies
Uncontrolled or observational studies only
Level of Evidence
? The amount of high quality evidence. The mo re evidence, the more we can trust the results.
Outcome Magnitude of effect
? The direction and size of the supplement's impact on each outcome. Some supplements can have an increasing effect, others have a decreasing effect, and others have no effect.
Consistency of research results
? Scientific research does not always agree. HIGH or VERY HIGH means that most of the scientific research agrees.
grade-c Coconut Oil Notable Very High See 2 studies
Appears to be comparable to mineral oil, the active control
grade-c Astaxanthin - - See study
grade-c Cocoa Extract - Very High See all 3 studies
Oral supplementation of cocoa flavanols does not appear to significantly influence skin hydration when compared to placebo.
grade-d Ginkgo biloba Notable - See study
The lone study assessing the effects of topical application of 0.3% ginkgo flavonoids in a cream noted a 28% increase in skin moisture content over 28 days, a highly relevant increase.
grade-d Moringa oleifera  
grade-d Rose Hip  
grade-d Salvia hispanica  
grade-d Saffron  

All comparative evidence is now gathered in our ​A-to-Z Supplement Reference.
