## What The Sources Report

- Human skin aging, marked by wrinkles, reduced elasticity, and dryness, is a major global public health and esthetic concern. [Sanjaya Gisela Meydilin (2026); evidence level 1]
- This shift reflects accumulating evidence that dietary antioxidants derived from plants can benefit both systemic and cutaneous health. [Sanjaya Gisela Meydilin (2026); evidence level 1]
- However, despite its effectiveness, HRT is associated with several drawbacks, which include increased risk of cardiovascular disease, breast cancer, and thromboembolic events. [Luan Haodi (2025); evidence level 1]
- Consequently, there is growing interest in exploring non-hormonal treatment options, such as the use of plant-based isoflavones, particularly those derived from soy, which may provide symptom relief without the associated risks of traditional HRT. [Luan Haodi (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 soy isoflavones skin elasticity 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.
