## What The Sources Report

- Background Nutrition is a modifiable factor in skin ageing, but its effects remain inconsistently quantified. [Ng JY (2025); evidence level 1]
- This meta-analysis assessed human studies from the Web of Science on dietary intake and skin ageing, using pooled standardised mean differences (pSMD). [Ng JY (2025); evidence level 1]
- Current challenges include a lack of standardization in extraction methods, a limited mechanistic understanding of bioactive interactions, and insufficient clinical evidence to substantiate health claims. [Jiang Xiaojing (2026); evidence level 3]
- Although this concentration is notably lower than the 30-35% typically found in tropical oils such as palm or coconut oil, PA remains integral to the unique therapeutic efficacy of SBSO. [Jiang Xiaojing (2026); evidence level 3]

## How To Read This Evidence

Evidence level 1 generally reflects systematic reviews or meta-analyses. Level 2 includes randomized trials, guidelines, or public-health guidance. Level 3 usually reflects observational or narrative-review evidence. Level 4 is weaker or early-stage evidence. The level is a sorting aid, not a final quality grade.

## Practical Interpretation

There is at least one systematic-review style source in the current set, so it deserves more weight than single-study evidence. For sea buckthorn skin hydration meta-analysis, the next editorial step is to add more targeted sources and separate strong findings from early or indirect evidence.

## Limits Of This First Pass

This is a small-batch MVP article. It uses the first ingested sources for this topic and should be expanded with more targeted searches, license review, and human editorial checks before being treated as a definitive review.
