# Astaxanthin Skin Meta-analysis: What the Evidence Says

## Quick Answer

Astaxanthin Skin Meta-analysis has 2 source documents in the current Migaku evidence database. The strongest available sources in this first pass are systematic review, so conclusions should be framed as evidence-aware guidance rather than medical advice.

## Key Takeaways

- This page is generated only from sources stored in the Migaku evidence knowledge base.
- Current evidence mix: 2 systematic review.
- Claims should be interpreted with the source type, study design, population, and publication date in mind.
- This article is educational and does not replace care from a qualified clinician.

## What The Sources Report

- Astaxanthin derived fromhas attracted considerable attention due to its potent antioxidant capacity; however, evidence regarding its effects on exercise performance and recovery remains inconsistent. [Wei Yan (2026); evidence level 1]
- By integrating available evidence, this study sought to evaluate the dual effects of algae supplementation on exercise performance and recovery, identify intervention characteristics associated with greater efficacy, and provide more targeted evidence for sports nutrition practice, and guide the design of future high-quality RCTs. [Wei Yan (2026); evidence level 1]
- Extended exposure to solar UV radiation has been associated with a range of negative impacts on the skin, including the development of wrinkles, dryness, hyperpigmentation, thinning of the topmost layer of the skin, heightened fragility, and noticeable changes in the elastic fibers of the underlying skin layer. [Yang Qifeng (2025); evidence level 1]
- Moreover, UV radiation is extensively acknowledged as a prevalent environmental carcinogen, and excessive exposure is closely associated with the development of skin cancer. [Yang Qifeng (2025); evidence level 1]

## 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 astaxanthin skin 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.
