Systematic Review and Meta-Analysis on the Effects of Astaxanthin on Human Skin Ageing

Systematic Review With Meta-Analysis

2021 Aug 24

The study found astaxanthin significantly helped skin moisture and elasticity, but the wrinkle reduction result was not statistically significant (p=0.11).

Gold Standard Evidence Needed

According to GRADE and EBM methodology, here is what ideal scientific evidence would look like to definitively prove or disprove this specific claim, ordered from strongest to weakest evidence.
