Evidence Map

What The Sources Report

• Combination Topical Antioxidant Protocol Enhances Laser‐Induced Improvement in Facial Pigmentation and Photoaging: A Prospective, Split‐Face Trial [Boo J (2026); evidence level 4]
• Nutraceuticals represent promising strategies for preventing, delaying and addressing premature aging of the skin, especially as women advance in years (particularly after 30 years of age, when estrogen levels begin to decline, and remarkably after menopause when estrogen production ceases from the ovaries). [Arbex P (2026); evidence level 4]
• This review is part of a larger project, and we present this companion review, which provides a detailed examination of the literature beyond polyphenols and/or phytoestrogens for estrogen-deficient skin. [Arbex P (2026); evidence level 4]

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

For vitamin c skin hydration randomized trial, the current source set is useful for orientation, but it is not yet broad enough for strong claims. Use cautious language and keep conclusions close to the cited sources.

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.
