## What The Sources Report

- Accordingly, peri-procedural strategies aimed at reducing inflammation and restoring the epidermal barrier are emphasized in clinical practice; however, standardized, evidence-based post-procedural protocols remain limited. [Boo Jihee (2026); evidence level 4]
- The use of adjuvant topical cosmeceuticals has increased to improve laser outcomes and reduce procedure-related complications. [Boo Jihee (2026); evidence level 4]
- Collagen, along with antioxidants such as curcumin and glutathione, have gained increased utilization/awareness in recent years, providing dermal health benefits especially in women who experience declining or loss of estrogen with aging. [Arbex Priscila (2026); evidence level 4]
- The evidence of oral collagen as a nutraceutical is robust for improving several aspects of dermal health. [Arbex Priscila (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 elasticity 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.
