Dietary studies report different changes in wrinkles, hydration and other skin measures
A pooled review found favorable results for several dietary components, but the outcomes differed. The abstract does not identify a single best option or show how noticeable the changes were.
Based on the published abstract. The full paper may contain additional methods, results and limitations.
The 30-second takeaway
The review found favorable pooled results for collagen, lipids and fatty acids, and polyphenols on wrinkles and hydration. Other results concerned redness, pigmentation, elasticity and water loss through the skin. The abstract does not establish which option would work best for an individual, or how noticeable any change would be.
This abstract-based summary lacks comparator details, study durations and participant characteristics. The review drew on Web of Science and English-language articles, limiting the scope of the evidence it captured.
Different measures answer different questions
The outcomes included wrinkles, hydration, redness, pigment spots, elasticity and water loss through the skin. A favorable result on one measure does not establish improvement on the others, so the findings should stay tied to each measured endpoint.
What pooled scores leave unclear
The review used standardized mean differences to combine results. These are not percentage improvements and do not directly show what someone would see or feel. The authors also identified evidence gaps for carotenoids and vitamins.
