Skin supplement review reports favorable findings for some products and uncertainty for others
Some supplements favored measured skin photoaging outcomes over placebo, while others did not show statistically significant benefits. The abstract leaves the size and visible importance of the changes unclear.
Based on the published abstract. The full paper may contain additional methods, results and limitations.
The 30-second takeaway
The review reported favorable skin photoaging outcomes for collagen, flavanols and other polyphenols compared with placebo, including skin elasticity or other measured changes. Hyaluronic acid, lycopene and carotenoids did not show statistically significant benefits; this does not establish an absence of effect. Some other supplements had insufficient evidence. The abstract does not quantify improvements or establish their visible importance.
Some findings were inconsistent or supported by sparse research. The abstract supplies no numerical effects or detailed safety results, limiting assessment of improvement size and the scope of the favorable safety summary.
Interpreting the measured changes
The review considered supplements taken by mouth. It reports favorable placebo comparisons for collagen, flavanols and other polyphenols, including changes in skin elasticity. The abstract does not provide numerical estimates showing how large those changes were.
Evidence and safety have limits
The authors describe inconsistent results and sparse research for some supplements. They report safety during the study periods, but the abstract provides no detailed adverse-event results or evidence addressing use beyond those periods.
